摘　　要：【目的】系统地分析贵港市建成区岩溶地面塌陷地质灾害分布特征和规律。【方法】从时间和空间上对贵港市建成区岩溶地面塌陷地质灾害分布特征进行分析。【结果】时间上,岩溶地面塌陷主要多发生在3月份和5月份;空间上,岩溶地面塌陷主要分布于地下水强径流带上,分布于岩溶发育较强烈区域。【结论】为该地区岩溶地面塌陷形成机理和发展趋势的预测提供有力的依据。[Purposes]To systematically analyze the distribution characteristics and laws of karst ground collapse geological disasters in Guigang City.[Methods]The distribution characteristics of karst ground collapse geological disasters in Guigang City were analyzed from time and space.[Findings]In terms of time,karst ground collapse mainly occurred in March and May.Spatially,karst ground collapse is mainly distributed in the strong runoff zone of groundwater and in the area with strong karst development.[Conclusions]It provides a strong basis for the prediction of the formation mechanism and development trend of karst ground collapse in this area.
