1.1 .1 The concept of environment
 The concept of environment

The term "environment" firstly used by German scholar E. Haeckel in
"ordinary biological morphology" published in 1866.
 Environment in ecology is the space surrounding a particular
organism or biological population, together with all the things directly
or indirectly affecting the survival of the organism or biological
population. "Environment" is the combination of physical
environment and biological environment.
 The environment researched in Environmental Science is the external
world where human beings are the mainstay, the complex of material
condition supporting human survival and development, including the
natural environment and artificial environment (Liu Peitong, 1984).
 The relationship between man and environment

 The "Environmental Protection Law in the
People’s Republic of China" promulgated in
December 1989 definitely states that, " the
environment is all of the inartificial and artificial
natural factors affecting human survival and
development, including air, water , ocean, land,
minerals, forests, grasslands, wildlife, natural
and human remains, nature reserves, scenic spots,
urban and rural areas. "
 Environment is the complex of nature, social,
culture and economy other than human being.

The integrity of environment
 Interrelation and mutual restraint among the various




factors of the environment
Mutual impact and dependence between local
environment and overall environment
The cycle and transformation of matter and energy
Cross-border (provincial, regional, national) environment
impact
Comprehensive and complexity of environmental issues
（3）
The regional of environment
The regional environment is the temporal and spatial distribution
difference of environmental factors, which shows as follows: ：
 The diversity of the global environment, focusing on
space, such as zonality of water and land.
 Variability of the local small environment, focusing on
time, such as season
 The complexity of environmental factors between
local and overall environment,such as the transmission
of pollutants spread through special transmission route.
（4）
Relative stability of environment
 Meaning: logistics, energy flow and information flow in environment are
constantly changing, the environment itself has a certain anti-interference
ability of self-regulation, in a certain range of disturbance intensity, structure
and function of the environment remain basically unchanged.
 Human system is an open system, human activities will affect the
environment.

（5） Hysteresis of environmental change

Meaning: the changes of the environment will be later than the outside
interference after the effect of the environment by external. For example: the
formation of ozone hole.
Satellite photos show the ozone hole
over Antarctica abnormally increase in
August
 Objectively ：

There are gradual and abrupt changes in the change of environment.

The performance of gradual change ：
(1) potential, delayed reaction; (2) It is difficult to predict the scope and extent of
environmental change; (3) the scientific definition of the threshold; (4) Scientific
quantitative determination of environmental recovery capability; (5) the indicators
of environment that can be monitored are not sensitive.
Mutation is the accumulation result of gradual changes
◇Subjectively:


Limited level of development of environmental monitoring
technology
Limited ability to predict environmental change
（6） The vulnerability of environment
 Meaning: Environment will be destroyed when the
interference intensity exceeds its threshold.

Environmental Bearing Capacity: is the support capacity
to development by environmental system.

Means "during a certain period, under certain environmental
circumstances, the threshold of support capacity to human society
economic activity by a regional environment”.

Substantial: the threshold of human activities which the human environment system can withstand under the premise of the
maintenance of harmony between human and the environment
The vulnerability of environment ——
 Incentive: the human "population explosion" pressure, the rapid
growth of demand
 Performance: Environmental problem
 The limited of Earth's resources, resources crisis
 The limited of Earth's environmental bearing capacity,
environment crisis
 Tasks: The human development model of the Earth damage to
the environment, ungently need to be improved
1.2 The environmental science and its development
1.2.1 Development history




Although in the ancient simple environmental scientific thought has been
produced,As an independent discipline
Environmental science was born in the 1960s. The symbol is the 《Silent
Spring》written by Rachel Carson in 1962 and the Scientific Committee of
environmental problems established by the International Union of Science in
1968.
Environmental science has been developing rapidly during 1970s to
1980s.The symbol is the United Nations Conference on Human Environment
in 1972 and the concept of "sustainable development" propounded by 《Our
Common Future》in 1987.
The discipline system became mature in 1990s. The symbol is 《 Rio
Declaration on Environment and Development》propounded by the United
Nations Conference on Environment and Development (UNCED) in 1992 and
Agenda 21.
Environmental science discipline has been more comprehensive in the
breadth and depth of the expansion in 21 century.
 The development of Chinese Environmental Science (see《We

Need Revolution》by Qu Geping , Jilin People's Publishing
Press, 1997)
During 1960s to1970s - the age of fearlessness led by ignorance .
1980s - the age of opening. Department of environmental science
or research institute began to be set up in universities and
research institutions.
1990's – the age of development. The first-class discipline of
Environmental Science and Engineering established by the State
and Ministry of Education in 1998. Sustainable development had
been one of the basic national policy.
21 century –the age of rapid development, wide range of
applications and close relation of environmental science and the
modern and future life of human being.
1.2.2 The study object of environmental science
 What Environmental Science research is the Earth environment human being live,
study scope of environmental science
other living and non-biological material on the Earth is considered as environmental
factors, which closely been related with human being. (Qian Yi, Tang Xiaoyan, 2000)
Environmental science is the science of coordinating the relationship between
human being and the environment correctly, searching the approach and mathods
of sustainable development of human society, during studying and guiding human
being understanding, using and transforming nature.(Sheng Lianxi, etc., 2002)
Environmental science is the science to solve environmental problems faced by
human, to create more suitable and better environment. (Zuo Yuhui, 2002)
Environmental Science is the systematic study of the natural and man-
made world. It is now a major discipline, reflecting our growing concern
about the impact of human activity on the natural world.（ARW Jackson &
JM Jackson，2000）
Environmental science-----
Object of study: the paradox of "human - environment" as the
research object, to study the unity of opposites of human and
environmental.

Objective of study: Discuss the impact on the environment by the
sustainable development of human society, and the changing regularity of
environmental quality, thereby to adjust the behavior of human beings to
protect and improve the environment for social, economic and
environmental scientific basis for sustainable development.
In short: coordinating the relationship between humans and the
environment
1.2.3 The task of environmental science
(1)Explore the evolution of global environmental law.
(2)Reveal the relationship between the human activities (production,
living) and the natural environment.
(3)Explore the climate change impact on human survival and human
activities impact on the natural environment .
What current environmental science urgently research is focus on the areas of belows:

Discuss the impact on the environment by the sustainable development of
human society, and the changing regularity of environmental quality.

Reveal the relationship between the human activities and the natural
environment. Explore the climate change impact on human survival and the
global environmental safety.

Help people to establish a correct concept of social development, research
and explore the environmental pollution control technologies and
management tools to solve environmental problems in different spatial scales.

1.3 Ideas and methods of environmental science

1. Integrity

Environmental science is characterized by emphasis on the integrity of
the object, human and environmental systems to be seen as the organic
integrity with specific structure and function .

The nature and function of integrated environment is much more
abundant and complex than the factors of environment. Collective
effect generated by interrelation and interactions of environmental
factors consititue the integrated environment.

Various changes in the environment are not isolated, but
comprehensive reflection of various factors. There are close relation of
interrelation and interrestriction of environmental factors .
 2. Systematicness
 Environment is a complex dynamic systems and open systems
with the changes of time,space,quantity and order.
 In environmental systems, there is interaction between various
subsystems and various components, and constitute a certain
network structure. There is material, energy and information
changes and exchange inside and outside of the environmental
systems. Achieve self-organization during the exchange
circulation, to maintain a certain function.

3. Comprehensive
 Because of the diversity and relevance of the studying object,
environmental science become more comprehensive.
 Environmental factors involved in natural factors and social factors, to
solve environmental problems need to do more research on
comprehensive subjects
4. Complexity
 Human environment system is a multi-level large-scale systems. The
interreactions among subsystems are very complex.The subsystem effect
on the integrated environment is also very complex.
 The interreactions between human being and environment are very
complex.
