On Water Resources Plan And Management Of Na Si Lake

Nan Si Lake basin multi- annual means water resources total quantity 6. 795 billion m~3, average per person 297. 4 m~3, surface water resources average per person 128 m~3 is lower than internationally recognized average per person lowest water resources, insufficient average per person 500 m~3 is seriously lacks the water the pilot wire, is serious to lack the water area. In the last few years, because water resources serious insufficient, surface water resources and ground water resources use factor continuously high, the ground water resources development use factor basically is in the tendency which grows year by year, the water resources development use factor excessively is high, has created the serious ecological environment problem, the local water resources development use has surpassed its bearing capacity. Adds on Nan Si Lake to be situated at the Soviet Lu Liangsheng intersection point, lacks the water resources unified plan and the effective management, the existence water used waste, further aggravated the water resources crisis, the local water resources crisis has seriously restricted the local economy sustainable development, has created the serious destruction to the lake district ecological environment. For coordinates between the good Nan Si Lake area and the life, the production and the ecological environment water used relations, the tube good uses Nan Si Lake the limited water resources, develops is extremely essential to Nan Si Lake the basin water resources plan and the management research.The present paper through the development water resources plan and the management research, provides the scientific basis for Nan Si Lake the water resources unification management. The paper main content includes:First, carries on the investigation and the analysis to the domestic extra income resource management progress and the present situation, in this foundation, elaborated the development Nan Si Lake water resources plan andthe management research importance.Second, the system introduced Nan Si Lake the area basic situation, the water resources and the ecological environment present situation, has analyzed the water resources and the water resource management present situation, as well as the water resources and in the water resource management exists the question, provides the essential foundation for the development Nan Si Lake water resources plan and the management research.Third, the research has analyzed the plan basic principle and the method, elaborated through needs the water forecast the theory form, establishes the water volume assignment model, carries on the science the water volume assignment plan, at the same time strengthens the water resources project management through the construction essential water resources project measure and the non- project measure, the safeguard water supply security.Fourth, elaborated unifies the management pattern through the basin management and the region management, proposed Nan Si Lake the water resource management overall plan.
