摘　　要：运用岩溶学、洞穴学理论及洞穴沉积物的形成机制,将洞穴的区域地质地貌条件和自然背景与洞穴次生化学沉积物发育过程联系起来,对云南多乐原溶洞群的洞穴结构、洞穴环境及洞穴沉积物特征进行分析,结合野外实地调研,探讨洞穴石钟乳分布情况、发育特征及主要影响因素,结果表明:研究区石钟乳发育特征表现为石钟乳个体形态各异、类型多样;垂向成层分布、群生为主;大型石钟乳发育突出;石钟乳出现拐弯现象。影响多乐原石钟乳发育的主要因素有区域的可溶性碳酸盐岩、水动力条件、二氧化碳浓度和二叠纪时期特殊的地理环境,这些主要影响因素和其他因素相互作用,形成了类型丰富、形态各异的石钟乳。Based on the theory of karst and cave science and the formation mechanism of cave sediments,the regional geological and geomorphological conditions and natural background of caves are connected with the development process of secondary chemical sediments of caves.The cave structure,cave environment and characteristics of cave sediments of Duoleyuan cave group in Yunnan Province are analyzed.Combining with field investigation,the distribution and development characteristics of cave stalactites are discussed.The results show that:1)The development characteristics of stalactites in the study area are as follows:individual morphology and types of stalactites are different;vertical stratification and clustering are dominant;large stalactites are prominent;stalactites are turning.2)The main factors affecting the development of Doraeyuan stalactites are regional soluble carbonate rocks,hydrodynamic conditions,carbon dioxide concentration and the special geographical environment of the Permian Period.These main factors interact with other factors and form various types of stalactites.
