摘要
根据景观生态评价的理论与方法,并结合露天煤矿开采对环境破坏的特点,构造了基于景观的稳定性和宜人性指标的露天矿区生态评价模型.以胜利矿区为例,通过选用多样性、代表性、空气污染浓度、重金属污染、土壤侵蚀、地下水污染等6项指标建立了生态评价指标体系,运用层次分析法对生态评价因子进行等级化处理,确定评价指标的权重,计算出各生态评价因子的综合评价指数(CEI)为0.96,表明该矿区的生态质量很好,能满足可持续发展的要求.
Based on the landscape ecological evaluation theory and the characteristic of environment destruction due to opencast mine activities, the opencast mine ecological evaluation model containing landscape stability index and suitability for mankind index was developed in this paper. Taking Shengli opencast mine as an example, the indexes such as diversity, representa tire, air-pollution concentration, heavy metal pollution, soil erosion, underground water pollution were selected to establish the ecological evaluation system. The value of each index was determined by the evaluation system, and their weight percentages were determined by using the method of analytical hierarchy process. Finally the composite evaluation index （CEI） was figured out as 0. 96, showing that the ecological quality of the Shengli opencast mine is very good and can satisfy the requirement of sustainable development.
