环境成本视域下生态系统服务价值的定量研究
|
摘要
针对环境退化成本问题,将其划分为三个方面进行解决。以唐山市土地利用H项目为例,首先构建了基于DEA的生态系统评估模型,对H项目生态服务水平进行评估,得出唐山市H项目的生态环境服务水平受土地利用负面影响较严重;然后利用治理成本与机会成本法算出H生态矿区土地利用项目的环境成本,得到2004年,2007年,2010年,2013年和2016年H项目的环境成本依次为1 236. 36万元、1 252. 11万元、1 106. 02万元、856. 81万元、729. 99万元;最后基于已测算得到的H项目的环境成本,构建了DS-BP综合成本效益模型,对H土地开发项目进行成本效益分析,为保证模型的适用性,引入另一个规模较小的M项目一起进行分析,得出H项目的综合成本效益比为0. 87,水平一般,M项目的综合成本效益比为0. 35,水平较好的结论;最后对模型的有效性进行了检验。
In view of the cost of environmental degradation,we established an ecosystem assessment model based on DEA. The ecological service level of H project was evaluated. It was concluded that the ecological environment service level of Tangshan H project was seriously affected by land use. The governance and opportunity cost method is used to calculate the environmental cost of the land use project in the H ecological mining area.The environmental costs of the H projects in 2004,2007,2010,2013 and 2016 are respectively 123. 636 million yuan,1,252,100 yuan,1,100,200 yuan,8,568,100 yuan,72. 999 million yuan; Finally,based on the estimated environmental cost of H project,the DS-BP comprehensive cost-benefit model is constructed to analyze the cost-benefit of H land development project. To ensure the applicability of the model,another small M project is introduced. The analysis shows that the comprehensive cost-benefit ratio of H project is 0. 87,the comprehensive cost-benefit ratio of M project is 0. 35.
