| 摘 要： | 以区域生态风险评价理论为基础,对煤炭矿区生态风险评价方法进行了研究,针对煤炭矿区生态环境特点以及煤炭开采可能对生态系统造成的危害,分析了矿区的风险源、风险受体以及生态终点,确定了煤炭矿区生态风险评价的指标体系和指标的赋值方法,建立了矿区生态风险估算模型及随时间变化的累积模型,通过计算风险累积速率进而求得矿区煤炭开采的风险累积值,为典型的煤炭矿区开采生态风险提供了一种新的评价方法。

| Abstract: | The ecological risk assessment method for coal mining was studied based on the theory of regional ecological risk assessment.Aiming at the eco-environmental quality of the coal-mining areas and the damages to the ecological system caused by coal mining,risk sources,receptors,and endpoints of coal mines were analyzed.The index system of ecological risk assessment for coal-mining areas was set up and value assignment method of the index was also given.The time-dependent accumulative ecological risk model for ... |
