摘要
以大庆市区湿地为研究对象,利用大庆地区2004年LANDSAT TM遥感图形解译数据和实地调查数据,采用地理信息系统技术(GIS),分析了大庆湿地的类型及分布特征;并选用替代法对大庆湿地进行污染物降解功能价值估算。研究表明,降解污染物功能主要是自然湿地所具有的功能,其次是人工湿地中的稻田湿地,经估算自然湿地降解污染物价值为17.90亿元,人工湿地降解污染物价值为0.017亿元,大庆湿地降解污染物价值17.92亿元。
The main wetland types and their distribution in Daqing were characterized with the data from interpretation of LANDSAT TM remote sensing images and the data from field survey in 2004,using Geographic Information System(GIS).The substitution method was adopted to estimate the values of degrading pollutants of the wetlands in Daqing.Results showed that,the function of pollutants degradation is most evident with natural wetlands,followed by paddy fields in artificial wetlands.The value of pollution degradation in natural wetland was estimated to be RMB 17.90 billion,and that in paddy fields was RMB 0.0017 billion.The total value of pollutants degradation in wetlands in Daqing was RMB 17.92 billion.
