摘要:

采煤沉陷湖由采煤地表沉陷经常年积水而形成,把采煤沉陷湖改造为人工湿地是近年来中国尝试的一种生态修复途径。由于采煤沉陷湖人工湿地对区域微观环境改良作用明显,从而对周边土地价格产生溢出效应。以平原高潜水位地区采煤沉陷湖人工湿地——九里湖湿地为研究案例,以商业和住宅用地为研究对象,分别采集九里湖湿地生态修复前后相同评估基准日的区域地价样点数据,通过Kriging空间插值生成价格曲面,以地统计和GIS栅格计算的方法测度了九里湖湿地对周边土地价格的溢出效应。研究表明,越接近九里湖湿地,土地价格涨幅越高,且明显高于九里湖湿地所在区域土地价格的平均涨幅,显示出九里湖湿地对周边土地价格产生了明显的溢出效应。经进一步测算得出,九里湖湿地对周边商业、住宅用地价格的溢出效应影响范围分别为21.07 km2和20.76 km2,影响强度分别为135.76元/m2、182.39元/m2。把溢出效应影响范围和城市规划用地进行套合,通过栅格计算得出,研究期间九里湖湿地对周边商业、住宅用地价格的溢出效应价值分别为20 225.64万元、20 507.09万元,其溢出效应的价值总量(ΔSE)为40 732.73万元。

Abstract:

A coal mining subsidence lake is formed by coal mining subsidence which is ponded by years. Transforming the coal mining subsidence lake into an artificial wetland is an approach to ecological restoration in recent years in China. As the artificial wetland in the coal mining lake has obvious effect on improvement of regional micro environment, spillover effect on surrounding land price of the artificial wetland in the coal mining lake is therefor emerged. This paper took Jiuli Lake wetland in Xuzhou City which is an artificial wetland in Plain area with high groundwater level, as study case, selected commercial and residential lands in the study area as a research object, collected data of land price samples on the same valuation date in 2007 and 2013 which are correspond to years before and after ecological restoration of Jiuli Lake wetland respectively, generated data of land price samples into land price surfaces by a way of Kriging spatial interpolation to estimate spillover effect of Jiuli Lake wetland on surrounding land price by a method of Geostatistics and GIS grid computing. The results show that the closer the land to the empirical study area is, the higher the land price increases, and significantly higher than the average price of the land in the region where the empirical study is located. It shows that Jiuli Lake wetland has obvious spillover effect on surrounding land price. After further calculation, impact ranges of spillover effect of Jiuli Lake wetland on surrounding commercial and residential land prices are 21.07 km2 and 20.76 km2 respectively, and impact intensities are 135.76 yuan/m2 and 182.39 yuan/m2 respectively. Combining the impact ranges with Xuzhou City lands planning, The values of the impacted land areas were ascertained. Through GIS grid calculation, values of the spillover effect of Jiuli Lake wetland on surrounding commercial and residential land prices are 202.26 million yuan and 205.07 million yuan respectively, the total is 407.33 million yuan.
