摘　　要：以兖州煤田1990~2018年4期遥感影像为数据源,利用改进的归一化水体指数方法(MNDWI)对兖州煤田水体信息进行提取,对兖州煤田水体演变进行时空分析。基于景观生态学方法选取斑块数量、景观形状指数、面积加权分维数、平均斑块面积等指标,从破碎化情况、形状变化及人为干扰情况等方面对兖州煤田水体演变进行定量化研究。结果表明,采煤活动导致塌陷水体面积不断增加,从1990年的214.38hm^2增加到2018年的2717.73hm^2,增长了近10倍;水体形状日趋不规则,受人为活动特别是采矿活动的干扰加强;水体斑块破碎度降低,连续型增强;水体斑块形状越来越复杂,受采矿活动影响程度增大。Based on the remote sensing images of Yanzhou coalfield from 1990 to 2018,the modified normalized difference water index(MNDWI)method is used to extract the water body information of Yanzhou coalfield,and the temporal and spatial evolution of the water body in Yanzhou coalfield is analyzed.Based on landscape ecology method,the number of patches,landscape shape index,fractal dimension index of area weighted mean and mean patch area are selected to quantitatively study the evolution of water body in Yanzhou coalfield from the aspects of frag mentation,shape change and man-made interference.The results show that coal mining activities have led to an increase in the area of subsided water,increasing from 214.38 hm^2 in 1990 to 2717.73 hm^2 in 2018,an increase of nearly 10 times.The shape of the water is increasingly irregular,which is enhanced by the disturbance of human activities,especially by mining activities.The plaque fragmentation of water bodies is reduced and continuous type is enhanced,the shape of water plaques is more and more complex,and the degree of influence by mining activities is increased.
