| 摘 要： | 广州金沙洲地区自2007年以来,发生多起地面塌陷及地面沉降地质灾害,严重威胁居民的人身和财产安全。本文首次采用递进分析法,高精度的对金沙洲地区岩溶地面塌陷、地面沉降地质灾害进行评价分区,并分别从地质灾害发育度、潜势度、危险度及危害度四个方面进行研究,对金沙洲地区地质灾害情况进行评价。研究结果显示：金沙洲地区地质灾害主要为岩溶地面塌陷和地面沉降,潜在因素为区内可溶岩的广泛分布及地下水作用,直接诱发因素为人类工程活动。本研究将金沙洲地质灾害易发程度分四个等级。

| Abstract: | There are many collapses and subsidence happened in Jinshazhou since 2007. People＇ s personal and property safety are threaten serious. This article is the first one trying to use AMFP method to evaluate the collapses and land subsidence geological disaster in Jinshazhou. It researched from geological hazards, assessment, risk and hazard four aspects and analysis the above four aspects generally. Results of the research shows： the main geological disaster in Jinshazhou is karst collapses and land subsidence. The latency is the widely distribution of the meltable rocks and the working of groundwater. The directly reason is the human contributions. This research divided geological hazards into four grades in Jinshazhou. |
