The Evaluation And Survey Of Environmental Water Of Xianghai Wetland In Jilin

A growing shortage of water resources,Rational development and utilization of water resources, Protection of the ecological environment,Maintain harmony between man and nature has become the 21st century mankind's common mission.Wetlands are aquatic and terrestrial environments to connect or mutual extension of the eco-region,which is an ecosystem with the richest bio-diversity and supreme ecological function of nature.The wetland is known as "the kidney of the earth",plays an irreplaceable role in resisting and regulating the flood,controlling and degrading the pollutant etc.Wetlands are important natural resources and natural resources,also is Wildlife Especially the most important habitat of the birds,forests,oceans and Wetlands are the three major ecosystems of the earth.Also have called "the earth kidney","cradle of life", "Bird Paradise","species gene pool","cultural cradle" by the people.Xianghai wetland have deteriorated of the ecological environment,Rivers drying up,grassland desertification and salinity increasing natural forests reducing,and the area are Shrinking day by day.Not only is the study of the cumulative basis,also help us understand the background of global changes in the natural evolution of wetland lakes.There is important practical significance to the socio-economic development and the local agricultural production.The result of the stud)," will provide reliable and informative evidence for management and governance of Xianghai wetland,and contribute to the evaluation of lake water and have long-term ecologic,social and economic benefits.The paper through the Xianghai wetland water at different area.On the basis of this right to the water quality and water conducting a prelinfinary evaluation and estimates.In accordance with the relevant national standards,use spectrophotometry for testing of the main surface water samples.The gradeâ…¢standard water of "Surface Water Quality Standards"(GB3838-2002) have been measured,the results showed that except the Permanganate Index over proof a little,TN and TP are all below the national standards.There is no eutrophication phenomenon recently.Because of the geographical position of the Xianghai wetlands and the decrease of precipitation in recently years,Lead to the wetland area decreasing year by year.This paper has the preliminary estimated for the eco-environmental water demand of wetland,transiting the way of development,utilization and management of water resource,and adjusting industrial structure,can save water resource and reduce pollution.People should utilize the water resource on the basis of guaranteeing the eco-environmental water demand of wetland.In order to full play every function of the Xianghai wetland better,and maintain wetland ecosystem's stability and development,the new proposal is put forward:implementing grain for green,wood and wetland with unique natural landscape and characteristic national culture,developing the eco-tour,while protecting the wetland eco-environment to realize the sustainable economic development of the wetland nature reserve.
