煤炭资源型城市生态系统服务功能的时空变化特征分析——来自2006—2015年安徽省淮南市的经验证据

Analysis on spatial-temporal change characteristics of ecosystem service function in coal resource-based cities: Empirical evidence from Huainan City of Anhui Province over 2006—2015

考虑到生态系统的品质性和稀缺性,对价值当量因子法模型进行拓展,并基于典型煤炭资源型城市淮南市2006—2015年的经验证据,系统分析了该地区生态系统服务功能的时空变化特征,研究结果表明,从时间角度来看,该地区生态系统服务功能价值总体在降低,主要是由于水源涵养、废物循环和气候调节这3种类型生态系统服务功能价值的减弱,不过下降趋势逐步减缓.从空间角度来看,该地区生态系统服务功能强度呈现东部、南部高,中部和北部偏低的格局,说明目前采煤区域的生态系统服务功能仍较脆弱,而传统矿区的生态系统服务功能正在得到恢复提高.

Given the quality and scarcity of ecosystem,this paper tries to extend the value equivalent factor model and use empirical evidence from the typical coal-based city of Huainan over the year of 2006 to 2015 to systematically analyze the spatial-temporal change characteristics of ecosystem service function in this area. The results show that,from the point of view of time,the ecosystem service value in this region is generally decreasing,mainly due to the decline in ecosystem service function values of water conservation,waste recycling and climate regulation,but the downward trend gradually slows down. From a spatial perspective,the intensity of ecosystem service function in the region exhibits the pattern of high levels in the east and south,relatively low levels in the central and north,which demonstrating that the ecosystem service function in the coal mining area is still relatively weak,while that in traditional mining area is improving.
