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).

7
  • The relationship between man and environment

8
  • The "Environmental Protection Law in the Peoples
    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.

(2) The integrity of environment
Boston
Jsmao.Aug.,2005
24
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

25
(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.

26
(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.

The changing process of environmental situation
in the pressure
27
(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
28
  • 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

29
(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

31
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

32
1.2 The environmental science and its
development1.2.1 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 Springwritten 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 Futurein 1987. 
  • The discipline system became mature in 1990s. The
    symbol is  Rio Declaration on Environment and
    Developmentpropounded 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.

33
  • The development of Chinese Environmental Science
    (seeWe Need Revolutionby 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.

34
1.2.2 The study object of environmental science
  • What Environmental Science research is the Earth
    environment human being live,
  • 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) 

study scope of environmental science
  • 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)

35
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 

36
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.

37
1.2.4 Subdiscipline of environmental science
According to the basic disciplines, study the
basic theory of environmental problems
blending with environmental science and social
sciences
combining theory with practice
38
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 .

39
  • 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.

41
  • 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.

42
