摘要
秭归县童庄河是湖北省三峡库区内的长江支流之一,流域内地质灾害主要受河流水系、岸坡结构和地质构造等因素的控制和制约,具有分布不均衡性、流域的集中性等特征。分析童庄河流域内地质灾害发育的时空规律特征,总结流域内地质灾害的发生与降雨的密切相关,其密集发育于水系两岸、顺向斜坡区、构造线附近,有针对性地提出其流域开发规划建议,规范流域内人类工程经济活动,对地质灾害采取工程治理为主、搬迁避让为辅的防治措施。
Tongzhuang river is one of the tributaries of the Yangtze River in the Three Gorges Reservoir area.The geological disasters in the basin are mainly controlled and restricted by the river water system,bank slope structure and geological structure,which are characterized by uneven distribution and concentration of the basin.This paper mainly analyzes the temporal and spatial characteristics of geological disasters in Tongzhuang River Basin,summarizes the occurrence of geological disasters in the basin,which is closely related to rainfall,and densely develops on both sides of the river system,along the slope area and near the structural line,and puts forward suggestions for basin development planning.It is necessary to standardize the econonic activities of human engineering in the basin,and take the prevention and control measures of geological disasters as the main control and relocation and avoidance as the auxiliary measures.
