耕地资源的非市场价值核算——以山东省日照市为例

Check and computation of non-market value of cultivated land resources:A case study of Rizhao city in Shandong province

以日照市近几年的耕地资源数据为研究基础,从剖析耕地资源非市场价值的角度出发,运用分解求和法、替代法、影子价格法、机会成本法等方法,选取2000年到2012年中的五个代表年份,按照耕地的社会、生态功能,分别测算耕地资源的养老保障、失业保障、社会稳定和生态功能等方面的价值。结果表明:日照市耕地资源的社会价值总量和生态功能价值总量波动较大,在一段时间内呈持续下降趋势,表明日照市应当全面的认识耕地资源的价值,尤其是重视其非市场价值。

We focus on analyzing the non- market value of cultivated land resources that provide key social and ecological functions, selecting the period of 2000 to 2012 .

The results show that cultivated land resources of Rizhao city social total value and ecological function of the total value of fluctuation is large , within a period of time continuing to show a downward trend .
