- 摘要:
- 生态效益的评价和核算对评价生态工程的建设效果至关重要.综合运用专家咨询、理论分析和频度分析3种方法,建立了秦州区水土保持林生态效益评价指标体系.使用市场价值法、碳税法、影子工程法、机会成本法和替代法等方法,对该区水土保持林年生态效益进行了价值核算.结果表明:秦州区水土保持林建设具有巨大的生态效益,核算后的总生态价值约为22197.8万元,其中,水圈生态效益9806.27万元,土圈生态效益65676.65万元,气圈生态效益137889.25万元,生物圈生态效益10825.31万元.该评价方法可为相似类型区水土保持林建设效益评价提供参考.
- Abstract:
- Valuing the ecological effects is crucial to the assessment of output of the forestry project.This paper suggested an assessment system for the ecological effects of soil and water conservation forest construction project in Qinzhou County,applying expert consultation,the layer analysis and the frequency analysis land the paper also calculated the value of ecological effects using market valuation method,carbon tax law,shadow engineering method,opportunity cost method,substitute expense method and so on.The results showed that the soil and water conservation forest construction project in Qinzhou County has produced tremendous ecological effects.The ecological value is up to about 22.42 billion Yuan(RMB) in total,among which contributed by hydrosphere ecology effects,atmosphere ecology effects,biosphere ecology effects and earth circle ecology effects increase are 0.98,13.79,1.08 and 6.57 billion Yuan(RMB) respectively.The results may be a reference for the assessment of ecological effects of soil and water conservation forest construction project being carried out in the similar type area.
