The water resources are important material base in developing national economy and essential factor of safeguarding the human survival and the society development. Since the 20th century, along with social and the economical development, the water demand has grown rapidly. The contradiction of water resource supply and demand has been more and more prominent.Therefore, reasonable development and use of water resource and taking master plan must be taken highly recognition for safeguarding society and the economy development and protecting the water resources environment for human survival.Average per person holding the water resource of Changchun is equal to 1/7 that of domestic, 1/20 that of the world. According to the international standard, Changchun belongs to the area of extremely lacking water. Along with the increasing of population and development of social economy, the issue of water resource is more and more prominent. Additionally, the lag of govenning pollution and bad management intensified the water crisis. In order to maintain the sustainable development, the reasonable planning of surface water environment and perfect city draining water and the sewage treatment system and establishing urban development and the aqueous system harmonious mechanism can drastically solve the problems which water environment is facing. Presently, the sustainable utilization of water resource is an important topic for the development of current society, economic, cultural, and environment,and has very important significance for speeding up the ecology urban construction Changchun, realizing the sustainable development, consolidating the achievement of "double creation", creating country health city, successfully holding 2007 the Asian winter game.In recent years as a result of the urbanized development, the natural water environment encountered the serious destruction. In the city area the most original majority of river systems are divided fill up, or changes to the ditch, is only surviving some water bodies in the park interior. Moreover, because of the city area natural charge of remittance ability and the water permeability with deeply water descend, the city local region accumulates aqueous of probability increment, and obstructed the rain water toward soil to permeate to a large extent, make the underground water level of city descend, make the water source of the river system fastens supply less and less. The urbanization causes the natural ecosystem of city surface river system to suffer injury, the city occupies to the land and the space creates the reduction of the natural ecological environment space, and causes the natural ecology develop to face the intense artificial ecology direction.The city surface water environment plan in view of the above surface water environment status quo and the existence question, the goal, the principle, the measure and so on of the city water environment to against the pollution, should comply with change of the condition, take the new understanding as the instruction, even more takes the city rivers in renovating the nature characteristic, the systematic characteristic and the diversity, complied with the nature evolution rule of the river lake, takes continuously the city river system important environment function and the ecology value which had been neglected. Proposed the subject is: the plan of the protection, the restores and the foundation.Because the Changchun surface water body pollution quite is serious, the surface waterbody pollution condition intensifies year by year, many water bodies already were 3 levels of specific weights pollution, even is 4 levels of serious pollution. This plan takes key the surface water body pollution government, first to analysis the surface water body present situation, the surface water pollution situation and the pollution origin has carried on, proposed in view of the actual situation and the concrete origin the sewage treatment plant construction plan, the source of the plan to against pollution, the main water body against pollution plan, and proposed the concrete water body pollution government implementation measure and the suggestion, makes every effort to restore and to strengthen the city river system each kind of function, safeguards it to the urban economy society sustainable development strut.
