中文摘要：

本文基于场论和GIS技术进行矿区生态环境的采动累积效应分析。论文首先介绍了生态场理论与相关概念;考虑到矿区生态场不同层次生态位与开采沉陷之间的因果关系,以及生态位元素对于揭示采动累积影响规律的敏感特性,构建了生态位元素体系;然后对研究区域进行生态元划分,并以此为单位对不同时相的遥感影像进行影像分类,利用分类结果专题图进行生态位元素值计算,作为累积效应研究的基础数据。论文主要介绍了土地利用/覆被态势指数及土壤侵蚀强度等生态位元素的量化与测算方法,描述了采动生态势的确定方法以及基于此进行生态环境采动累积效应分析的程序方法。最后以潞安矿区某开采沉陷区为研究对象进行了示例分析,得到该矿区主要生态位元素的采动累积效应规律。

英文摘要：

The cumulative effective of mining-induced eco-environment was anzlyzed based on ecological field theory in the paper.Ecological field theory and relevant concepts were first presented.The causal relationship between different niche level and mining subsidence was taken into account.The sensitive character of niche element for the cumulative effective was also considered.A niche element of system was then constructed.The research areas were divided into different types of eco-unit.Different phase remote sensing images were thus classified.The results were used to calculate the niche value.The quantification and calculation method of such niche elements as land use and its coverage indices and soil erosion intensity were mainly introduced in the paper.The determination of mining-induced eco-potential and the approach of cumulative effective analysis were described Lu-an subsidence areas were finally selected as the case area.The mining-induced cumulative effective laws of the case area were acquired.
