基于遥感影像的富锦市生态系统服务价值分析

摘要

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.%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2919713．47万元下降至2010年的1671722．54万元；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。
