重庆金佛山岩溶作用驱动因素初探
PRELIMINARY RESEARCH ON DRIVING FACTORS FOR KARSTIFICATION IN JINFOSHAN, CHONGQING
【摘要】 走向北东—南西向的向斜和近东西向的横张大节理等地质构造控制了金佛山岩溶作用发生的空间展布方向。下二叠统的中厚层块状灰岩及生物碎屑灰岩给金佛山岩溶作用的发生提供了坚实的物质基础。4~10月这一温暖湿润的气候特征加大了金佛山岩溶作用发生的强度和速度。茂密的森林植被和及其植被分带性在进一步促进了金佛山岩溶作用发生的同时,也导致了金佛山岩溶作用强度在时空分布上的差异。
【Abstract】 The spatial direction of karstification in Jinfoshan is controlled by the NE-SW syncline and transverse tension joint and other geologic structures. Abundant materials for karstification in Jinfoshan are provided by medium or thick-bedded blocky limestone and biologic clastic limestone of the Lower Permian system. The speed and intensity of karstification in Jinfoshan are strengthened by the warm and humid weather from Apr. to Oct.. The thick vegetation and the zonal distribution of plants in various altitudes not only further accelerated the karstification in Jinfoshan, but also lead to the differences in spatial-temporal distribution of karstification intensity at the same time.
