摘要
收集巢湖1957~2003年气象、水文资料,利用巢湖地区多时相航空、航天遥感数据,结合环湖野外地质、地貌及水位调查,从自然因素与人为因素两方面分析巢湖湖岸崩塌的成因:1多组北东向、北西向断裂构造宏观上控制着巢湖崩塌岸分布,地层岩性微观上影响崩塌程度;2降水、风速和风向等气象因素影响水位变化,进而形成湖岸崩塌的时段性;3人类生产、生活活动特别是对巢湖大闸不合理调控等人为因素造成水土流失、泥沙淤积进而抬高水位,亦是加剧崩塌的原因之一。
The Chaohu lakeshore's collapsing is investigated and analyzed on the basis of the remote sensing data of aerial photos and satellite images at different times.The course of the Chaohu-lakeshore's collapsing was analyzed from viewpoints of natural and artificial factors by combining with field geology,physiognomy and water level investigation,gathering Chaohu Lake's weather,hydrology datum from 1957 to 2003.①the structure factors causing the Chaohu-lakeshore's collapsing in fracturation and stratum's lithology;②the weather factors for lakeshore's collapsing,including precipitation,wind and water level;③the man-made factors for lakeshore's collapsing.
