浑河流域森林生态补偿标准测算

Measure of Forest Ecological Compensation Standard in Hunhe River Basin

[目的]测算浑河流域森林生态补偿标准,为建立流域森林生态补偿机制提供科学依据。[方法]以浑河流域森林生态补偿为研究对象,在应用ArcGIS 9.3计算流域上游向下游空间转移的森林生态服务价值基础上,利用主成分分析法得到浑河流域下游各市县社会经济发展水平测算出来的补偿系数,最终确定浑河流域森林生态补偿标准。[结果]沈阳市森林生态补偿标准最高为4.12亿元/a,大洼县森林生态补偿标准最低为0.07亿元/a。[结论]森林生态服务价值转移量随着距离上游地区空间距离增加而减少。得到森林生态服务价值转移量越多,补偿系数越大,补偿标准越高。

[Objective]The forest ecological compensation standard in Hunhe river basin was measured in order to provide a scientific basis for making forest ecological compensation mechanism of the river basin.[Methods]This paper determined forest ecological compensation standard by using principal component analysis to form compensation coefficient,defining the development standard of society and economy,and calculating the forest ecological service value from top to bottom with ArcGIS 9.3,which took forest ecological compensation in Hunhe River basin as an example.[Results]The highest forest ecological compensation standard of Shenyang City is 412 million RMB every year,and the lowest is 7 million RMB each year in Dawa County.[Conclusion]Forest ecological service value was gradually reduced with the increase of the distance from the upstream.The more forest ecological service values from the upstream were,the bigger the compensation coefficient was,and the higher standard of compensation was.
