兴隆庄煤矿生态系统服务价值评估

以兖州矿区兴隆庄煤矿为例,基于1990-2018年间的遥感影像数据,从供给、调节、支持和文化4个方面对兴隆庄生态系统服务价值进行测算评估,并分析其动态变化度及敏感性。评估结果表明,总生态服务价值表现为先增加后减少,1990-2010年矿区生态系统服务总价值从18841.5万元增加至29034.2万元,主要原因是采煤塌陷导致耕地向塌陷水体转变以及林地面积的增加;2010-2018年生态总价值减少了2484.8万元,主要在于耕地大规模地转变为建设用地以及区域地下水位下降造成的水域面积减小。敏感性分析显示,耕地和水体是平原矿区生态系统服务价值最敏感的因素,耕地的敏感性指数由1990年的0.79降为2018年的0.28,说明其在生态服务价值中的影响逐年降低。

Evaluation of ecosystem service value in Xinglongzhuang Coal Mine

Taking Xinglongzhuang Coal Mine in Yanzhou mining area as an example,based on the remote sensing image data from 1990 to 2018,this paper estimated and evaluated the ecosystem service value of Xinglongzhuang Coal Mine from the aspects of supply,regulation,support and culture,and analyzed its dynamic change degree and sensitivity.The results showed that,the total value of ecological services increased first and then decreased and from 1990 to 2010,the total value of ecosystem services increased from 188.415 million Yuan to 290.342 million Yuan,whose reasons were the transformation of cultivated land to collapsed water caused by coal mining collapse and the increase of forest land area;from 2010 to 2018,the total ecological value decreased by 24.848 million Yuan,mainly due to the large-scale conversion of cultivated land to construction land and the decrease of water area caused by the decline of regional groundwater level.The sensitivity analysis showed that cultivated land and water were the most sensitive factors for ecosystem service value in plain mining areas,and the sensitivity index of cultivated land had decreased from 0.79 in 1990 to 0.28 in 2018,indicating that its influence on ecosystem service value had been decreasing year by year.
