基于多时相的遥感影像数据，对张集采煤塌陷积水区十多年的时空变化和水环境富营养化状态进行动态监测。结果表明：研究区自2001年建成投产以来，塌陷积水区面积逐年增加，面积达到近900hm2，2013年5月积水区水体为轻度富营养化水平，同时从春季到冬季，张集采煤塌陷积水区水体富营养化呈现先上升后下降的趋势。

Based on multitemporal remote sensing image data carried out dynamic monitoring of temporal and spatial variation more than a decade and water environment eutrophication status in mining subsidence ponding area, Zhangji coalmine. The result has shown that the study area since 2001 constructed and put into operation, ponding area increasing with years, acreage reached near 900 hect?are. Up to May 2013, ponding area water body amount to mild eutrophication level;meanwhile, from spring to winter, water body eutro?phication presents a trend of increasing first then decreasing in the ponding area.
