摘要
以最新发布的《中国森林生态系统服务功能评估规范》为依据,根据2007年苏州市森林资源规划设计调查资料,对苏州森林生态系统的涵养水源、保育土壤、固碳释氧、营养物质积累、净化空气、物种保育、景观游憩等生态服务功能价值进行初步评估。结果表明,苏州森林生态系统单位面积服务功能价值为69255元(/hm2·a),总价值为446830万元/a,其中涵养水源价值为167910万元/a,保育土壤价值为59614万元/a,累积营养物质价值为25235万元/a,固碳释氧价值为76023万元/a,净化空气价值为25629万元/a,物种保育价值为86148万元/a,景观游憩价值为6271万元/a。
Starting with discussing about the concepts of service function of forest ecosystem, and by means of forest assessment data, monitoring data, related data and specifications for assessment of forest ecosystem services, which were used to calculate the ecosystem service values of water conservation, soil conservation, nutrient element accumulation, carbon fixation and oxygen release, air purification, bio-diversity conservation and tourism. Results showed that the ecosystem service values was 69255y/ （hm^2,a） , yearly total ecosystem service values was 4468.29million yuan RMB. The benefit of water conservation was1679.01 million yuan RMB. The benefit of soil conservation was 596.14 million yuan RMB. The benefit of nutrient element accumulation was 252.35 million yuan RMB. The benefit of carbon fixation and oxygen release was 760.23 million yuan RMB. The benefit of air purification was 256.29 million yuan RMB. The benefit of bio-diversity conservation was 861.48 million yuan RMB and 62.71 yuan RMB for tourism.
