基于遥感影像的富锦市生态系统服务价值分析

生态系统服务和土地利用实质上是相互影响、相互制约的关系,定量研究县域土地利用与生态服务价值的变化情况,为生态资源的合理定价与有效补偿、促进自然生态系统与社会经济系统的协调发展提供了科学依据。本文基于遥感影像,在GIS、RS技术支持下,分析了富锦市1990~2010年生态系统服务价值变化情况。研究结果表明:富锦市1990~2010年土地利用的生态系统服务价值总体持续降低,由1990年的2 919 713.47万元下降至2010年的1 671 722.54万元;生态系统服务价值量与其土地利用变化密切相关,当土地利用类型改变时,生态系统服务价值量也随之改变;人口和经济是研究区生态系统服务价值的主要驱动因素。

The Analysis of Ecosystem Service Value in Fujin Based on Remote Sensing Image

The relationship between ecosystem services and land use is essentially mutual influence and mutual restriction, county land use quantitative research and the change of ecosystem service value provide a scientific basis to the reasonable pricing and effective compensation of ecological resources ,and also provide a scientific basis to promote the natural ecosystem and social economy coordina-ted development of the system.Based on remote sensing image ,in the support of GIS, RS technology,we analyze the changes of Eco-logical service value from 1990 to 2010 in Fujin.The results showed that:(1)1990-2010, the ecosystem services value of land use overall reduced continuously, from 29.197 134 7 billion yuan in 1990 fell to 16.717 225 4 billion yuan in 2010, a total of 1.2913899 billion yuan;(2) Ecosystem service value had a close relationship to the change of land use, when the land use type change, ecosys-tem services value would be changed;(3) Population and economy was the main driving factor of ecosystem services value.
