摘要
桂林特定的气候、地理、地质环境，使碳酸盐岩地层中发育的洞穴形态多、数量大，洞穴系统复杂。本文依据该市面积１７３ｋｍ范围中的４８８个钻孔资料，对峰林平原地下洞穴发育的密度、形态、规模、深度、充填物等特征进行了初步分析研究。
The cavesdeveloped in the carbonate layers in Guilin are manifold in shape large in quan-tity and complicated in cave system due to the specific climte，geography and geology. Accord-ing to the data from 488 drill holes in 148 Km2 area，the author preliminarily analyzes andstudies the density，scale，depth， fillings etc. of the caves developed beneath the hoodoo plain.
