Ecological Environmental Protection in Chian
2 min readThe General Plan should look at the situation as a whole，not only consider the water demand in the North，but also consider the ecological effect in the South.
In the General Plan，the ecological and environmental protection plan is coordinated with the plans of pollution control and ecological construction of the four river basins of Changjiang，Huanghe，Huaihe and Haihe，some of these plans are under implementation.According to the characteristics of ecological and environmental impact，the whole area is divided into water source area，route area and water use area.Ecological and environmental protection plans for each area were worked out.The research on the impact on the Changjiang river mouth has been carried out.Four issues on ecology and environment were raised，namely，the ecological protection of the middle and lower reaches of the Hanjiang River，the prevention of salt water intrusion into the Changjiang river mouth，the safe operation of the middle Route，and pollutant cutoff and drainage of water logging.
Mode of water use has to the changed，a unified and optimized allocation of the diverted water with local existing water should be implemented.It is planned to complete the Ten-Year Harnessing Works of Huanghe，Huaihe and Haihe Rivers，Pollution Control Project in the East Route and Water Resources Protection Project of the Capital in the 2lst century.It also includes supplementary projects for ecological protection of the middle and lower reaches of the Hanjiang River and water diversion area of the Changjiang estuary.Safe protection system will be designed for the water conveyance structures so as to ensure the ecological safety of the area.An overall plan for ecological and environmental protection will be worked out which will be implemented during the process of Project construction.The plan should have definite objective，countermeasures and tasks.
Defining the project scale in accordance with Urban Water Resources Plan for “South-to-North Water Transfer”Project，Water Resources Plan of the Haihe River Basin and the results of rational water resources allocation in the Huanghe，Huaihe and Haihe River Basins.
The project scale should match with the volume of water demand.For this reason，relevant departments and scientific research institutes were organized for makin the Plan on rational allocation of water resources in the Huang-Huai-Hai Area andWater Resources Plan of the Haihe River Basin，as well as water resources plans fo 44 cities at the prefecture level along the East and Middle Routes of the Project.
