摘　　要：秦皇岛柳江盆地的砂锅店地区发育有面积约0.04 km^2的岩溶地貌,面积虽小,但岩溶地貌类型齐全、溶蚀程度高,并且还在持续发展中。研究认为,比较纯的石灰岩、发育充分的构造裂缝、形成汇水区的凹地、下倾方向发育的岩浆岩岩墙等因素都为岩溶作用的发生创造了有利条件。该地区污染严重,大气中高浓度的SO2、CO2与降水结合后生成H 2SO4、H2CO3,是当前溶蚀作用仍在发生的主要原因。In the area of Shaguodian in Liujiang Basin of Qinhuangdao,the karst landform with an area of only 0.04 km^2 is formed.Although the area is small,the karst landforms are of complete types and high degree of dissolution,and they are still in continuous development,which is very rare in north of China.It is believed that the pure limestone,the development of structural fractures,the barrier of magmatic rock wall to groundwater in the down-dip direction,the catchment effect of small basin,the effective configuration of stratum tendency and the direction of rock wall and groundwater seepage create favorable conditions for karst geological process.The local pollution is serious.The high concentration of SO2 and CO2 in the atmosphere combined with precipitation forms H2SO4 and H2CO3,which are the main factors of the current dissolution.
