土地利用/覆盖变化遥感研究表明,大庆市自1988年以来土地利用状态变化很大,由此引起了该区域生态环境的一系列响应及其生态系统服务价值的变化。以大庆市1988年和2001年的Landsat TM图像解译数据为基础,应用Costanza等人对全球生态系统服务价值的测算方法,分析了该市土地利用变化及其所引起的生态系统服务价值的变化。研究结果表明,13年间,大庆市土地利用的变化损害了该区域生态系统的生态服务功能,使生态系统服务价值损失了20.76%-24.01%。
The application of remote sensing technology to the study of land-use/coverage change show that there were severe variations in aspect of land use in Daqing City since 1988 ,which brought on a series of responses of regional eco-environment and the variation of its ecosystem service values. Based on the data of Landsat TM for the Daqing City in 1988 and 2001, this paper analyzed changes in land use and ecosystem service values using Costanza's method of evaluating the global ecosystem service values. The results indicate that the ecosystem service values of Daqing City have been diminished due to the land use change in 13 .years. The loss of ecosystem service values has reached 20. 76% - 24. 01%.
