摘要
以唐山市大南湖生态区为研究对象,依据SPOT高清遥感影像数据,运用GIS技术手段,通过人机交互式目视解译,获取唐山市大南湖区2002年、2009年土地利用数据库,结合生态服务价值理论,对唐山市大南湖生态区2002年、2009年的生态环境进行定量分析评价。结果表明,2002年唐山市大南湖生态服务总价值为1 042.84万元,2009年为1 661.34万元;对比前后跨度8年的数据,治理后的大南湖生态环境发生了显著变化,其总生态服务价值提高了59.3%。
Taking the Dananhu Lake ecological zones as the research object,based on SPOT HDV remote sensing image data,GIS technology and human-computer interactive visual interpretation,the databases of land use in 2002,2009 were obtained.With the ecological services value theory as the theological framework,a quantitative analysis and evaluation of the ecological environment of Dananhu lake zones in Tangshan City in 2002 and 2009 was conducted.The results showed that the total ecological services value of Dananhu Lake in Tangshan city was 10.428 4 million in 2002 while in 2009 this figure reached 16.613 4 million.In conclusion,Dananhu Lake ecological environment after treatment has undergone significant changes;and the total value of ecological services was increased by 59.3%.
