    Regional variation of forest ecosystem services in China

    • 摘要: 森林生态系统在维护环境和提供生态服务方面发挥着重要作用,对森林生态系统服务功能的价值评估是目前的研究热点。采用由国家林业局发布的统一评估体系和计算公式,利用第7次全国森林资源清查数据,对全国各省区的森林生态系统服务功能进行了评估,并在此基础上,采用多边形综合指标法进行综合评价与分级。结果表明:中国森林生态系统服务功能总价值为100 147.61亿元/a;各省区单位面积森林生态系统服务功能价值量主要分布在4.00万~5.00万元/(hm2•a)之间;我国各省区的森林生态系统服务功能水平分布不均,各省区间差异较大;低纬度和高纬度省区的综合评价指数较高,中纬度地区的省区综合评价指数较低。

       

      Abstract: Forest ecosystem plays an important role in maintaining environment and supplying ecosystem services. Evaluation of forest ecosystem services is a hot topic. Under the framework of evaluation criteria published by the State Forestry Administration of China for forest ecosystem services, the 7th forest resource inventory was used to evaluate the value of forest ecosystem services in China. By using the polygon synthesis indicator method, each province got a score of integrated assessment. The results showed that the total value of forest ecosystem services was RMB 100 147.61×108 per year in China. And the unit value of different provinces ranged between RMB 4.00×104-5.00×104 per hectare per year. The distribution of forest ecosystem services was not even among different provinces, with the higher integrated assessment indices in the high- and low-latitude provinces than those in the mid-latitude provinces.
