Research conclusions: For the last 30 years，the ground collapse of Guangzhou has been in the wave raising state with the obvious space － time distribution regulations． The human factor and heavy rain are main reasons for the ground collapse and they centrally happen in flood period from April to October． The karst collapses mainly happen in the hidden karst areas of the Huadu District，Baiyun District and Chonghua City within the Guanghua Basin． The ground collapse caused engineering mainly happens in the main city proper of Guangzhou． The underground excavation and pumping underground water can cause the ground collapses and they are proportional to the engineering volume and engineering strength． The plan as a whole，scientific site selection，adjusting structure and reasonable arrangement are the control countermeasures for the ground collapse．
