沛北煤矿区景观生态风险评价
Landscape ecological risk assessment in Peibei coal mine area
【摘要】 文中以景观生态、区域生态风险评价理论为基础,结合高潜水位煤矿区采煤塌陷特征,以多期遥感影像为数据源,定量分析煤矿区景观生态风险。研究结果表明,沛北煤矿区景观生态风险性偏低,受到景观结构、植被覆盖和塌陷积水等因素影响。
【Abstract】 Based on the theory of the landscape ecology and the regional ecological risk assessment,combining with the characteristics of coal mining subsidence in high groundwater level coal mining area,and using multi-period remote sensing image as data source,the landscape ecological risk in coal mining area was quantitatively analyzed.The results showed that the ecological risk of landscape in Peibei coal mine was low,which was affected by the landscape structure,the vegetation cover and the subsidence water.
