高潜水位矿区生态系统演变趋势研究:以淮南潘谢矿区为例

为了有效地应对高潜水位矿区煤炭资源开采后带来的生态环境问题,以淮南潘谢矿区为研究区域,应用遥感技术分析了耕地、水体分布以及景观格局,分析了生态系统结构的变化,得出了矿区生态系统结构总体变化规律以及不同生态系统相互转化规律。应用开采沉陷预测技术,基于矿区生态系统结构的变化规律,预测了生态系统演化趋势,得出的结论为:耕地面积逐年减少,矿区煤炭资源完全开采结束时,矿区的生态景观将由水域占绝对主导优势,矿区由陆地生态系统向水陆复合生态系统演变,土地利用模式将优化。

Study on the change trend of mine area ecosystem with high ground-water level:a case study of Huainan Panxie mine

In order to effectively addressing the problems of ecological environment caused by the exploitation of coal resources in mine area with high ground-water level, taking Huainan Panxie mine area as a case,applying remote sensing technology to analyzing plough, the distribution of water and landscape pattern, then analyzing the change of ecosystem structure, drawing the law of overall change of mining area ecosystem structure and transformation between different ecosystems. Based on the change law of mining area ecosystem structure,applyingprediction of mining subsidence to calculating the change trend of ecosystem,conclusion that agricultural acreage will decrease year by year,after finishing the coal resources, water area will be the dominant advantage in mine area ecological,and mine area will be aquatic-terrestrial complex ecosystem instead of terrestrial ecosystem,the land use pattern will be optimized.
