Development laws and controlling factors of karst in Longyan, Fujian province, China

摘要

Longyan is a main region developing karst in Fujian province, China. Based on the extensive studies, this study systematically investigated the development law and controlling factors of the karst in Longyan. The results indicated that the development of karst in this region is mainly controlled by the lithological association of soluble rocks, and geological tectonics serves as the main controlling factor, while the effect of the groundwater in karst area constitutes the dynamic condition. Meanwhile, karst is also influenced by various factors including topography. The combined effects mainly led to the uneven distribution and development of karst in this region.
