摘要
研究区岩溶形态有地表岩溶及地下岩溶,即为岩溶洼地、落水洞及地下岩溶体系。影响岩溶发育的因素有地层岩性、构造、地貌以及水交替条件;岩溶发育具有成层性;库尾的F1、F2断层破碎带附近、坝首及右库岸的三级阶地出露带岩溶较发育。
Karst depression,sink hole and interstratal karst system are developed in the studied area,especially,nearby F1 and f2 fracture zones as well as third terrace.The development of karstification is controlled by stratigraphy,lithology,structure,landform and hydrogeological conditions.
