    煤矿区生态储存估算及其对土地利用的综合响应评价

    Estimatioin of ecological storage and its comprehensive response evaluation to land use transformation in coal mining area

    • 摘要: 为对煤矿区生态储存估算及其对土地利用的综合响应进行评价,以山西省位于长河流域的晋煤集团11个集中连片煤矿区为例,在生态服务功能理论的基础上,通过收集研究区10a的土地利用类型以及矿区与非矿区的相关数据,分析各类土地利用类型的面积、分布和变化方向,并建立评价指标体系以估计不同时期的生态储存,进而得出煤矿区基于煤炭开采的生态储存的响应。研究结果:研究区整体的生态储存呈下降趋势,除了天安圣华,其他煤矿区的生态都出现不同程度的退化,且矿区的退化速度远高于非矿区;12个区域中(11个煤矿区和1个非煤矿区)有一半以上区域的生态储存等级为第3级,研究区11个煤矿区的生态储存能力普遍较高,生态改善的可能性较大,可为煤矿区生态保护规划以及相应的管理提供基础数据和应用借鉴。

       

      Abstract: Abstract: Coal is one of the main energy sources in China. However many years coal mining activities have accelerated the speed of regional land use change, which not only causes serious ecological environmental disasters, but also destroyed the structure and function of whole regional ecosystem. The response of ecological storage and conservation in the process of land use change plays an important part in guiding the exploitation of coal resources, optimizing the land resource use and protecting the ecological environment in coal mining areas. Eleven concentrated and coterminous coal mining areas in Shanxi Province, located in Changhe River Basin, were taken as a case. Based on the theory of ecological service and the data of land use of last 10 years with its related information, the area, distribution and the change direction for all the land use types in the mining area were analyzed, the ecological storage of 11 mines at different times were calculated on basis of evaluation index system, and finally the response of ecological storage to land use change in coal mining area was gained. It was found that Ecological Storage State (ESS) in the study area showed a downward trend. Not including Tian'anshenghua, the ESC of other areas exhibited varying degrees of degeneration and the degradation rate of mining areas was much higher than that of non-mining area. Ecological Storage Capacity(ESC)in the study was relatively good, and the ESC values of all regions (including 11 mining areas and 1 non-mining area) area were positive. Tian'anshenghuamine had the best ESC value. Nevertheless Tian'an Haitian mine was the worst; Ecological Storage Pattern (EP) values in all mine regions were negative, indicating that these areas have the low ecosystem diversity, and the ecosystem was under a very unstable state. Affected by coal mining in the nearby mining area, the EP value of non-mining area was also negative. In addition, the EP values of all the mining area were greater than that of thenon-mining area, which can reflect the adverse effects on the ecological environment from the coal mining. For Ecological Storage Condition (LC), Chengzhuang mine with the largest number of bare land in the study area had the highest LC. However, the mine of Tian'anweiding, Tian'anhaitian, Tian'anbiying, Tian'anshenghua and Tiantaiyuenan had LC of 0, because all land had been utilized. For the comprehensive response evaluation of the ecological storage to the land use change, more than half of the 12 regions (including 11 mining areas and 1 non-mining area) in this study had a third level of ecological storage, but all the 11 mines had higher ecological storage capacity. So there was a great possibility for them to improve ecological environment. This research could provide the basic data and application references for the ecological conservation planning in the mining area.
