Since the development still remains
unbalanced, non-environmentally friendly
and unsustainable, China is in a transitional
phase in which social conflict and
environmental risk interact. The
environmental problems that appeared at
different stages of industrialization in
developed countries occur all at once in
China. The main features of China’s
environmental problems are structural,
compact and combined.

“We must fully implement the overall plan for promoting economic,
political, cultural, social, and ecological civilization construction, ensure
coordinated progress in all areas of endeavors in the modernization
drive……”
— Report to the 18th National Congress of the
Communist Party of China, 2012
“optimization of spatial development structure; promote all-around resource conservation; intensify
protection of the ecosystems and the environment; enhance institutional construction of ecological
civilization.”
1. Requirements for Ecological Civilization Construction
To promote ecological civilization, we must establish complete and integrated
institutions and systems with which the ecological environment is protected,
establish the strictest possible systems for managing water resources and improve
the system of accountability for ecological and environmental protection and the
system of compensation for environmental damage. ….To improve environmental
treatment and ecological restoration institutions that guarantee environmental
conservation.”
——Communiqué of the Third Plenary Session of the 18th Central
Committee of the Communist Party of China
Adopt economic incentives instruments to tackle
environmental externalities
Secure the smooth implementation of environmental
protection with institutions and legal systems
1. Main Tasks of Ecological Civilization Construction

The total volume of pollutants discharged
has significantly exceeded the carrying
capacity of water environment. Water
pollution appears to be watershed-specific,
structural, combined and long-lasting.
2. Main Features of Water Pollution in China
Huge pollution discharge, the largest COD and ammonia emitter in the
world, with amounts of new emerging contaminants being detected;
Serious urban air pollution;
One of the areas with serious aquatic ecosystem degradation.
Aquatic biodiversity threat ( 2010, Nature)
Survey on Fishes in the Yangtze River: Some experts claim that
the ecosystem of the Yangtze River is now facing severe
challenges.
It is warned in the 2013 Joint Research Report of
the Upper Stream Yangtze River, that the fishery
resource in the upper stream of Yangtze River is now
seriously degrading, with certain special rare fish
endangering. There is red alert in the ecological
protection of the Yangtze River.
2. Main Features of Water Pollution in China
• Er’hai Lake remains
“excellent’.
• Haihe River basin, Heihe
River basin are “very
poor” and “poor”.
• The rest seven
watersheds are “fair”.

2. Main Water Pollution Problems
China’s Water Pollution Prevention and Control Law states “Environmental management should
focus on improving water quality and on controlling the total amount of major contaminants
discharged into the environment.

Unscientific water quality-target: focusing on the reduction of total amount of pollutants and
drinking water safety, while neglecting aquatic ecosystem health;
Disparity in different water pollution control systems: environmental quality, total amount
control and discharge standards are disconnected, with the water quality-based discharge
permit system established incompletely.
Lack of integrated watershed management: water resources are not linked with water
environment, with watershed planning and regional management disconnected
Protecting water environment from the perspective of
nature and system engineering
Factors influencing water environment include: natural conditions of underlying
surface, land use pattern, discharge activities, etc.
Reforming the conventional water management system
Aim at protecting ecological integrity, while restoring environmental quality
Implementing more systematic mode with engineering
means
Promote reduce, re-use and recycle in the process of resource development,
production, circulation and consumption
3. Requirements of Ecological Civilization Construction on Water
Environmental Protection
Implementing integrated watershed management concept of
“mountain-water-forest-farmland-lake”
Mountains, waters, forests, farmlands and lakes make up of a community of life in a way that lifelines
of the people come from farmland, farmland comes from water, water comes from mountain, mountain
comes from the earth and the earth comes from tree. Management of their usage and ecological
restoration must follow the law of nature.

3. Ecological Function Zoning and Protection of Aquatic Ecosystem Health
Based on the spatial difference of aquatic ecosystem functions,
conduct aquatic ecological function zoning, propose specific
aquatic ecosystem protection targets and implement differentiated
protection measures for aquatic ecosystem heath.
Breakthrough Class I-IV
zoning technology of

Develop Class I, Class II
and Class III zoning
scheme in ten key
watersheds, such as
Liaohe River and Taihu
Lake, etc.
Established the technical
system and methods for the
development of
environmental standards;
Proposed threshold values
for 12 major pollutants of
three categories;
The new amendments to Environmental Protection Law in 2014
calls for conducting research on environmental criteria.
3. Establishment of Water Environment Criteria and Standard System
3. Establishment of Capacity-based Total Pollution Load Control System
Environmental carrying capacity is identified through the ecological
service function of watershed, so as to protect the health of water
ecosystem.
The new amendments to
Environmental Protection Law in 2014:
pollution discharge permit system
should be implemented according to
national laws
• Propose capacity-based pollution load
control of control unit system
• Demonstration in 30% of control units
in Liaohe River, Taihu Lake and
Ganjiang River
• Capacity-based pollution discharge
permit system
220 key technologies were developed for petrochemical, metallurgical,
pharmaceutical, dying, food processing industries, which were demonstrated
in more than 70 big projects. BAT technical screening for 5 industries is
proposed.
3. Establishment of Whole Process Water Pollution Control System

An early-warning technical system for incidental, cumulative water
environment risks was established, initially realized the integration
of technical systems and the construction of business platform.
The early warning system for
water environment risks in the
Three Gorges Area supported
the water pollution emergency
drill on Dec. 16, 2010, shortening
the response time from several
days to several hours.

4. Water environment problems in Liaohe River
Main pollutants: COD, NH3-N
Water environment is restoring, changing from heavy pollution to light pollution.
Conventional aerobic pollution problems are eased, but toxic organic pollution problems are
emerging, becoming a potential risk.
NH3-N has become the outstanding conflict between water quality and water ecological
restoration.

Pursuing development
through environmental
protection
Closing Remarks
The natural property of water environment should be
respected. The prerequisite for the utilization of water
environment is that the natural property of watersheds
shouldn’t be damaged. Socio-economic development
shouldn’t be obtained at the costs of environmental
quality degradation, watershed natural integrity loss and
ecosystem health deterioration.
Keep the harmony between human, nature and water
environment!
