| 摘 要： | 龙宫水系主要由东、西两支组成，两支流之间在一年中又根据季节不同而通过地表溢流或地下伏流相串通。挽近以来由于新构造强烈抬升、河流强烈下切，喀斯特地貌回春发育，由北而南呈现峰林溶原→峰林谷地（盆地）→峰丛谷地（洼地）的系列更替。龙宫地区洞穴成因及发育与地下河系变迁密切相关，上层洞呈潜流型水平穿洞的特点；中下层洞往往相连，洞顶钟乳石发育、底部为现代地下河床，追踪构造薄弱带垂向下蚀，具有明显的裂隙洞特征

| Abstract: | The Longgong drainage system consists of western and eastern branches connected by surface overflow or underground rivers in seasons of a year With the neotectonic uplift and river incision, the karst landforms were rejuvenated and distributed by an alternation of fenglinplain, fenglin-valley (basin) and fengcong-poljie(depression) from the north to the south Formation and development of the caves in the area are strongly related to changes of the underground river system The upper-levelled caves are characterized by through-cave with phreatic features The middle/lower-levelled caves, speleothem on the roof and riverbed on the floor, are connected with each other and developed deppdard along structural weak zone Fissured-section of the caves are visibale |
