基于Meta分析的矿业城市生态服务价值转移研究

采矿活动剧烈干扰了区域土地利用,对生态系统健康造成了严重影响。论文在综合国内若干资源型城市生态系统服务价值研究实例的基础上,提炼系列指标参数,运用Meta分析方法建立并验证了专门针对矿业城市耕地、林地、草地、水域的价值转移模型,并以河北省武安市为例估算了1987、2001和2014年的生态系统服务价值。研究结果表明：1）价值转移模型可以有效地评估矿业城市生态系统服务价值;2）武安市生态系统服务总价值呈现先增后减的趋势,2001年之后呈现快速下降状态;3）从地类面积来看,1987—2014年间武安市经济发展对生态用地产生的干扰程度为：耕地>草地>水域>林地,从服务价值角度看,干扰程度为：耕地>水域>草地>林地;4）在生态用地总面积减少的情况下,适当优化生态用地土地利用结构可以提高生态系统服务总价值。

A Study on Transfer of Ecosystem Service Values in Mining Cities by Meta-analysis

Mining activities seriously interfere with the regional land use, which lead to a strong influence in ecosystem. After collecting many studies related to ecosystem service values (ESVs) in resource-based cities in China, this paper extracts a series of variables with Meta-analysis to establish benefit transfer models for assessing ESVs of cultivated land, forest land, grassland and waters especially in mining cities, then examines the feasibility of these models in Wu’an City to evaluate the ESVs of Wu’an in 1987, 2001 and 2014. The results show that: 1) the benefit transfer method can effectively assess the ESVs in mining cities; 2) there is a declining trend after the increase in the total ESVs of Wu’an, and a significant decrease occurred after 2001; 3) from the aspect of land area, the degree that the mining activities interfere with the land use type is cultivated land>grassland>waters>forest land from 1987 to 2014; from the aspect of the ESVs, the degree that the mining activities interfere with the land use type is cultivated land>waters>grassland>forest land; and 4) when the total area of ecological land reduces, a reasonable optimization of ecological land structure can improve the total ESVs rather.
