The Research Of Water Environment Quality In Zha Long Wetland

Wetland ecosystem as juxtaposed with forests and sea of global ecological system, and is one of the three global climate and environment protection plays an extremely important role. Wetland is like aquatic environment and the special natural, it is located in biosphere, hydrosphere, lithosphere, and the atmosphere in the northwest various flow and logistics exchange and function of the place, Wetland or earth important living environment and ecosystems and species diversity of plants and animals and microbes extremely rich. A lot of research and experiment show that wetland has keeping waterhead, flood disaster, adjusting the climate, groundwater, stable environment, soil erosion control, protection and utilization of resources gene species of multiple functions, and wetland also contain abundant biological resources, peat resources and natural resources, known as "the kidney", "human" and "human gene cradle.Zha Long wetland is to the west of the climate in Hei Long Jiang province, the ecological environment plays an important role in regulating, so it is very important ecological and environmental and economic value. At present, China has exceeded the speed of water pollution is the world, wetland and biodiversity of the most serious threats, it directly led to the destruction of wetland ecosystem function and structure of the degradation, many natural wetland nature reserve has become a pool of water, sewage, pile serious environmental pollution, thus launching Zha Long wetland protection water environment evaluation is imminent, for wetland nature reserve of reasonable exploitation and protection, provides the theory basis for both the profound historical significance, and universal significance.This article chooses the widespread adoption of environmental science evaluation methods. The first three evaluation methods, fuzzy evaluation method, the main grey evaluation method and artificial neural network method in Zha Long wetland, for the target area, the three evaluation methods are analyzed, Then through the Zha Long wetland environment situation investigation and water samples, combining Zha Long wetland sampling and laboratory analysis of samples, the Zha Long wetland quality and quantity analysis evaluation. In water purification function, spring, summer, autumn respectively in Zha Long nature reserve swamps and lake wetland water sampling, analyzes its TP, COD, the concentrations of ammonia and nitrate concentrations and decay, and the function of water purification Zha Long wetland seasonal difference, and the affecting factors are analyzed, In the study of water in Zha Long wetland rainfall and evaporation variation are analyzed, and finally the Zha Long wetland that individual monitoring-station of water variation and variation trend.The water that Zha Long wetland environment faces and problem solving, and puts forward a series of measures for protection, rational for the future of the wetland protection measures, provides the theoretical foundation for the reserves management provide scientific basis, to protect wetland ecological environment quality, improve the level of management of wetland resources also has important practical guidance.
