本文采用遥感(RS)获取信息和地理信息系统(GIS)建库分析相结合的方法,对徐州贾汪矿区1987-2007年煤炭开采过程中形成的塌陷积水区的数量变化、形态特征变化以及破碎度变化特征及其成因进行了研究,结果表明1987-2007年间,由于开采活动的不断进行,常年积水塌陷区的面积逐步增加;1987-1997年10年间,季节性塌陷积水区与常年塌陷积水区具有相似的变化特征;1997-2007年10年间,由于部分矿井停止开采及土地复垦的推行,季节性塌陷积水区的数量锐减,斑块形状变得规则且分布趋于分散。
In this paper, the method of combination of remote sensing (RS) acquisition and GIS database construction was used to analyze the quantitative changes and morphological characteristics of collapsed water areas formed during the coal mining process in Jiawang Mine of Xuzhou from 1987 to 2007, The variation characteristics of crushing degree and its causes were studied. The results show that the area of subsidence area of perennial stagnant water increased gradually from 1987 to 2007 due to the continuous mining activities. Between 1987 and 1997, In 1997-2007, due to the discontinuation of mining and the implementation of land reclamation, the number of seasonal collapse waterlogged areas dropped sharply, and the shape of the patches became regular and the distribution tended to be dispersion.
