三江平原湿地生态环境状况研究

采用微观监测和宏观监测相结合的方式,对三江平原湿地类型与面积、湿地水质、生物多样性进行了研究,并分析近5年内湿地景观的变化情况。结果显示:三江平原湿地以沼泽湿地为主,部分地区湿地水质受到污染,主要污染物为高锰酸盐指数、生化需氧量、氨氮和石油类;湿地生物多样性丰富;2004～2009年,三江平原各类湿地面积变化很小。

Research on Eco - environment of Wetland in the Sanjiang Plain

Through the method of microscopic monitoring and macroscopic monitoring, this paper researches on the type and area of wetland, water quality of wetland, biological diversity of wetland, and analyses the change of wetland in recent five year. Conclusion is that marsh is the main wetland in Sanjiang Plain. Wetland water quality has been Contaminated in some area. Main pollutants is Salt permanganate index, Biochemical oxygen demand, Ammonia nitrogen, Petroleum hydrocarbons. Biological diversity of wetland is rich.
