大庆湿地及水分调节功能价值估算研究

Research on Main Types of Daqing Wetland and the Estimated Value of its Water Regulation Function

以大庆湿地为研究对象,结合大庆地区2007年LANDSAT TM遥感图像解译数据和实地调查数据,采用地理信息系统技术(GIS),分析大庆湿地的主要类型及湿地分布特征,选择影子工程法进行大庆湿地水分调节功能价值估算。研究表明,大庆湿地所提供的水分调节功能价值主要为稻田和芦苇沼泽湿地调控洪水价值、湖泊湿地蓄水价值,经估算稻田和芦苇沼泽调控洪水价值为4.65亿元,湖泊湿地蓄水价值为1.43亿元,大庆湿地水分调节功能价值为6.08亿元。

Taking Daqing wetland as research object,its main types and distribution characteristics were all analyzed.Combined with LANDSAT TM remote sensing graphical interpretation data and the field survey data of Daqing area in 2007,the water regulation value of Daqing wetland was estimated using shadow project method based on Geographic Information System（GIS）.Research shows that the moisture adjustment function value provided by Daqing wetland is mainly flood control for rice paddies and reed marshes,and water storage for lake and wetland.Through estimation,it shows that the value of rice paddies and reed marshes in flood control is 465 million yuan,while the value of lake and wetland in water storage is 143 million yuan.Therefore,the value of Daqing wetland in water regulation function is 608 million yuan.
