INTRODUCTION
Under certain conditions, natural selection will
favor animals that use resources prudently, so that ecological
prudence can be developed as an instinctive trait of some animal
species, (see Gadgil 1985). These conditions embrace the following
aspects:
1) Resources are scarce or their stock is perceivably
limited. In such a situation, the maintenance phenotype of population
will be favored instead of the dispersal phenotype by means of
natural section (Geist 1978).
2) Resources are defensible. This means the prudent group will
not be deprived of the product by invaders.
3) The animal group as a whole can benefit from the prudent behavior
of each individual in the long run. This is self-evident if we
keep in mind that individuals act as representatives of genes
(Geist 1978); it is the gene that is selfish. Individuals will
save as much of the resources as possible for the coming generations.
4) The group must be well organized and pure enough. That means
the group can effectively kick out and control individuals who
behave profligately towards the environment, and fight against
invaders to protect their prudent products.
It is reasonable to deduce that only when these four conditions
are met simultaneously will animal species evolve adaptive prudent
behavior as an instinctive trait. According to the dispersal theory
(Geist 1978), traits of animals, especially mammals, evolve mainly
during dispersal when resources are abundant, so profligacy will
be more common among animals. Man as an animal was evolved with
his first bold step into the Savanna rather than into the periglacial
region characterized by rich resources, so the human lacks a system
of physiological or neural controls over gratification (Bennet
1980) and ecological prudence can not be a trait of human beings.
However, culture is just ways of adaptation, and much of the cultural
behavior of human beings has adaptive value (Cavalli-Sforza and
Feldman 1981; Plog and Bates 1980) . Thus when a certain culture
develops under the conditions mentioned, ecological prudence may
become a trait of the culture. In the following pages, we will
see that the Chinese culture (of agriculture) , as adaptations
to the basin environment, has developed a pattern of ecologically
prudent behavior toward the natural environment.
THE BASIN EXPERIENCE OF CHINESE CULTURE
We are convinced, for the following verifiable
reasons, that Chinese ways of coping with the environment are
mainly adaptions to the basin environment that Chinese agriculture
has long experienced.
1) From Homo erectus yuanmouensis dating back
to around 1.7 million years ago to the dawn of agricultural civilization,
Chinese Hominid ancestors were distributed among mountain basins
and valleys along the edges bordering the three major physical
geopraphic zones: the East Monsoon zone, The Northwest Arid Zone
and The Tibetan Alpine Zone.
2) The multi-centred Neolithic cultures in China
developed along with the distribution pattern of pre-Neolithic
cultures, with their centres in basins surrounding the great north
China plain, which was not yet stable for settlement during this
period because of the floodprone Yellow River (The History of
Chinese Civilization 1989) .
3) The Zhou people, which made the most important
contribution to Chinese culture, evolved during the period in
the Guanzhong Basin in mid Shanxi Province which was of optimum
size. Actually, it was this magic basin that gave birth to the
first written Chinese book I Ching (Yu 1990a), which is considered
as the most important source of Chinese culture. When one notices
the fact that the Chinese culture has hardly ever moved too far
away from the Classics, one may better understand the significance
of the ecological experience in the Guanzhong Basin to Chinese
culture, especially to the adaptive ways coping with the environment
(Yu 1990a) . In Chinese history, "fighting for power"
usually occurred on the great north China Plain, but it was surrounding
areas away from the great plain that nurtured powers like the
Zhou people, which then came to be displayed on the great plain
(Liu 1987). Recognizing the main flow of the Chinese culture as
an agricultural one, the author emphasizes that the surrounding
basins which were more suitable for agriculture must be taken
in special consideration.
4) "Fighting for power on the Central Plain"
has led repeatedly to the formation of "no-man's land"
(Jin et al 1990). To escape death the civil residents fled into
the hilly area of south-east China, where a series of small basins
act as natural refuges. This was especially obvious during the
dynasties of Eastern Jin (317-420 AD) and Southern Song (1127-1279).
It made the Chinese model their ideal society on a basin, which
is vividly illustrated by Tao Yuanming's "the land of peach
blossoms" from the Eastern Jin Dynasty.
5) From the geographical distribution pattern
of the Chinese population, one can see that the population is
most densely distributed in the Sichuan Basin, Guanzhong Basin,
south-east China's hilly land, etc (Wu and Zhang 1984; Jin et
al 1990). This has further strengthened the basin characteristics
of Chinese Culture.
6) The Theory and practice of Feng-shui, which
sum up typical ways that Chinese cope with their environment,
were mainly developed against the background of the hilly landscape
in south-east China, and the ideal Feng-shui mode is actually
an idealized basin (Yu 1990c, 1991a, 1991b). The rules of Feng-shui
have made the rural landscapes so beautiful and ecologically healthful
that even modern scientists can not help expressing their admiration
(e.g. Feng and Wang 1989; Lip 1987; Needham 1962; Skinner 1982)
.
7) Because of the backwardness of land transportation,
basins that have always had a glorious agricultural civilization
during the long history of water-way transportation have still
kept the splendid traditional agricultural landscapes intact.
However, according to modern standards of value, they are the
"third world" in this country and need to be developed,
and the only way for the development of these areas is eco-development.
Thus, Chinese agriculture has experienced and will continue to
experience a basin environment, which has always had a great influence
on the evolution of ecologically prudent behavior in Chinese culture.
The effects of the basin on the evolution on the prudence will
be investigated as follows.
BASIN EXPERIENCE FAVORS THE DEVELPMENT OF CULTURAL
ECOLOGICAL PRUDENT BEHAVIOR
The basin landscape with its well defined, isolated
spatial characteristics well meets the conditions, i.e. resources
are scare and defensible, the group as a whole benefits from prudent
behavior, and the group is to be well organized and pure, which
induce ecologically prudent behavior. This can be analyzed in
the following aspects:
1) A basin forms a well defined and stable "eco-cultural
region" (Dasmann 1985) . A moderate-sized basin will be occupied
completely by a culturally uniform society (a family or patriarchal
clan), and the cultural space and the natural bio-region will
come to coincide completely, making the society as a whole establish
an intimate relationship with the natural environment. This makes
it possible for the inhabitants to have an overall understanding
of the structure and function of the basin ecosystem. It leads
to the early development of an ecological sense as in Chinese
culture (Yu 1990a) and development of culturally and ecologically
prudent behavior.
2) Basin experience favors the sense of territory
and a posterity-oriented ethic. In an isolated enclosed basin,
the survival and development of the whole family of clan rely
completely upon perceivably scarce resources in the limited basin;
every member of the occupant group is brought up hearing the heroic
tales told by his parents and grandparents about their ancestors'
arduous struggle and merits in pioneering and maintaining and
protecting their sacred territory. All these lead to strengthening
the sense of territory and give rise to ancestral worship. Ancestral
worship particularly means to each member of the clan that: (a)
He acts not for himself but as a representative of his worshipped
ancestors for the preservation of the "gene" of this
family; his most important function is to take the lantern (as
a symbol of ancestral worship from his father and pass it on his
son); (b) Everything left from the ancestors is sacred and should
be kept intact and inherited by the descendants. Thus, a well
dug by ancestors, a field opened by ancestors, etc, should be
protected and carefully maintained for posterity.
3) Basin experience favors pure and well organized
groups. According to Brower (1980), there are four space occupancy
types: personal occupancy, community occupancy, occupancy by society
and free occupancy. In the situation in a moderate-sized basin,
community (family or clan) occupancy is dominant; the whole basin
can be claimed by a single family or clan as territory and there
is very limited room for outsiders and individuals. Any intruding
outsiders will be viewed with suspicion and kept off by making
use of and constructing defensive landscapes (Fig. 1). Profligate
individuals who dare to misuse the clan-claimed common territory
will be severely punished and even removed according to domestic
disciplines. That makes sure that the group as a whole can get
predictable long-range benefits from its prudent behavior.

Province)

3. the ancestral temple; 4. vegetable plots;
5. cottages; 6. ponds;
4) Basin experience induces an endogenous and
self-reliant economy. Thanks to the isolation and enclosure of
basin, the economic behavior of the habitants is need-oriented
but not imitative. The purpose of production and resource exploitation
is merely daily consumption instead of selling in the markets.
The flow of energy, material and information in and out of the
basin is very limited, so that the economic behavior of human
beings is the feedback mechanism of the ecosystem, instead of
the social and cultural information control mechanism. This makes
the habitant group behave in correspondingly adaptive ways including
acting prudently towards the natural environment.
5) Basin experience of partial and frequent calamity.
Compared to the situation in a great plain like that Mesopotamia,
the basin landscape is heterogeneous and complex. Natural calamities
caused by excessive use of resources and destruction of the ecosystem
within a basin are mostly local and limited to the basin. They
occur as a warning rather than unexpectedly, which gives the society
as a whole an opportunity to adjust its behavior towards the environment.
The characteristics of basins, such as a great contrast in relief,
seasonal changes in the water flow, etc, determine the frequent
occurrence of natural calamities as external stimuli acting upon
the society and guaranteeing constant adjustment of cultural behavior.
6) Basin experience influences other social and
cultural factors that are favorable to the development of prudence.
For the stable social environment in the basins, population may
be close to saturation for long periods and isolation can delay
the development of technology so that people have to rely upon
traditional resources and technology to earn a living. This means
that prudence will generally be necessary.
The above discussion makes one convinced that
the basin experience of Chinese agriculture obviously contributes
to the development of ecologically prudent behavior in Chinese
culture. However, ecological prudence is not unique to Chinese
culture. Gadgil (1985) has shown that certain species are especially
protected in India in the form of nature-worship and religious
belief, which are considered to be ecological prudence originating
in the hunting and gathering age, and even the so-called "aggressive
culture" of Christianity (Gadgil 1985) has its tradition
of "love for nature" (Vroom 1985). What should be emphasized
here is that prudent behavior in Chinese culture is not merely
for the purpose of sustainable use of certain resources but mainly
the health of the general agricultural and living environment,
and it has not originated mainly from hunting and gathering experience
but from agricultural experience. This will be illustrated with
some typical ecologically prudent landscapes in the following
paragraphs.
TYPICAL ECOLOGICAL PRUDENT LANDSCAPE ENGINEERING
Settlements located at the edge of basins
In moderately-sized basins, slopes at the basin
edges will be given priority when selecting sites for settlements
(Fig.2, 3). South-facing slopes especially are comparatively poor
in soil and water conditions for crops, and during the establishment
of the settlements, when the theory and practice of Feng-shui
usually play a very important role, the natural landform will
be changed as little as possible so that the "dragon vein"
and "earth's breath" can be preserved intact. The law
of "design with nature"(McHarg 1996) has been exercised
by the Chinese for thousands of years in the landscape in rural
China.

Guangdong Province

basin
Feng-shui Forest and Its Function
Certain species of tree are protected for their
special function as food, medicine resources, etc. in many cultures
(FAO 1985; Fortman 1984; Gadgil 1985). While the main function
of Feng-shui forests commonly seen in rural China is accumulating
"Qi", which can be recognized as the multiple ecological
function flow of energy, material, species and information (Yu
1991a) it also maintains the health of the general environment
of agriculture and living, but not merely preserving species as
special resources. For this reason, Feng-shui forests are usually
distributed on upper-slopes and tops of hills, at the "water
mouths" where water flows in and out of basins, etc. where
the forests are most effective in preventing soil erosion, reserving
water resource, alleviating flood, wind and drought and improving
a favorable microclimate. Fig.4 shows a mountain village in northern
Gunagdong Province, located in a small basin surrounded with limestone
hills. It has a population of more than 300 people, who live by
a small spring; it is the surrounding Feng-shui forest that keeps
the spring alive. Though trees on the other side of the hills
have been cut indiscriminately, the Feng-shui forest remains intact
and is as old as the village itself. The species in Feng-shui
forests are themselves not worthy of protection, they are usually
the most common and native ones, such as species in the genus
Cinnamomum. For this reason, the general ecological function of
Feng-shui forests can be realized most effectively. Water Conservancy
Landscape Engineering

on which the village lives (a preliminary survey by the author,
in northern Guangdong Province)
In the hilly land of south-east China, floods
usually come along with rainy season and drought with the dry
season. Water conservancy projects are therefore typical ecological
landscape features in basins.
For example:
1) Protection of "water mouth" and
rationing system of water resource: Forest and temples are commonly
seen near the "water mouth" and spring as signs of protection.
If several clans or villages share the same water source, water
will be distributed according to a peace treaty, which is usually
the result of long and fierce fights among villages. Through wisely
designed water courses, water will be rationed among members of
the same village. The water rationing system in the village Hongcun
in hilly southern Anhui Province is a good example (Fig.5). water
is drawn from a stream all through the upper half of the village
with a tortuous channel that flows by the step of each house;
this channel is called "ox intestines" by the local
people. Such a water distribution system among members of a village,
as well as among different villages, can promote in every resident
the sense of responsibility for water resource prudence; thus
Hardin's tragedy of the commons"(Hardin 1968) can be avoided.

southern Anhui Province (a preliminary survey by the author)
2) Ponds for water reservation and reuse: Ponds
in front and in the center of a village are a common landscape
feature in the Chinese countryside. To continue with the case
in the village Hongcun, the "ox intestines" channeled
water into a semi-circular pond, called the "ox stomach"
in the center of the village, which was used as a spring and was
preserved and expanded during the construction of the village,
so that more people could use the water simultaneously. Beyond
this "stomach", water is then again channeled tortuously
through the lower part of village and drained into a much bigger
pond, the "ox belly", where water is rich in organic
matter, and fish can be hatched and lotus cultivated. These ponds
are functional in regulating the microclimate and making the "dragon
vein" flourish as alleviating flood, drought and fire. Besides
this, they improve the scenery of the rural landscape, which has
a significant psychological effect upon the residents.
SUMMARY AND CONCLUSION
The ecologically prudent behavior of Chinese
agriculture was successful in that it had maintained a steady
and sustainable space for Chinese to have a peaceful and harmonious
life for thousand of years, and it contributed greatly to the
long-lasting agricultural civilization in China. However, it was
also a failure if one notices the fact that it had made Chinese
farmers live in an autarky and not go beyond that. However, in
realization of ecodevelopment in rural China, the ecologically
prudent mechanism of traditional Chinese agriculture, whirrs has
evolved during a long period of ecological experience and has
adaptive value, should be taken into serious consideration. At
the time when we are designing an "ecological city"
(Wang 1988) with the ideal of "high efficiency and harmonious
relationship", the traditional "ecological rural China"
is undergoing relentless destruction, and we should never forget
that in such a great agricultural country, the restoration of
a healthy rural agricultural environment, if destroyed, will be
much more difficult than that of an urban environment.
