摘要
应用1991、1999、2006年3期LandsatTM影像解译数据,在Constanza生态系统服务价值理论基础上,确定单位面积生态系统服务价值系数,研究了广东省肇庆市鼎湖区1991～2006年土地利用变化对生态系统服务价值的影响。结果表明,鼎湖区生态系统服务功能价值净增52.6×106元,增加率为5.17%,基塘用地的大幅增加是主要原因;生态系统单项功能服务价值中,气候调节、水源涵养、废物处理、娱乐文化服务价值在增加,气体调节、土壤形成与保护、食物生产、原材料生产、生物多样性保护等服务价值在减少。
Using Landsat TM image interpretation data in 1991,1999 and 2006,based on the Constanza ＇s ecosystem services value theory,the service value coefficient of unit area of ecosystem was confirmed.The effects of land use change on the service value of ecosystem in Dinghu District,Zhaoqing City in Guangdong during 1991-2006 were studied.The results showed that the ecosystem service value had a net increase of 52.6 × 106 yuan and the increase rate of 5.17% in Dinghu District.Its the main reason was substantial increase in land-based pond.Among the individual features of ecosystem service value,the value of climate regulation,water conservation,waste disposal,recreation and cultural services increased,but the value of gas regulation,soil formation and protection,food production,raw materials,bio-diversity protection decreased.
