利用1979～1998年昆明市地面沉降监测资料分析昆明市南部地区，即二环南路以南地区大面积地面沉降。该地区形成两个明显的漏斗形沉降区，一个是以小板桥为中心的沉降区，其中在朱家村、巫家坝机场、广卫村、小喜村、六甲、官渡等地较为明显，在沉降中心(小板桥)沉降量达227.5mm(1985～1998年)，平均下沉速率在 17mm/a左右，最大达30.00mm/a；另一个沉降中心在海埂以北的河尾村、渔户村一带地区，沉降中心的沉降量达100.4mm(1993～1997年)，下沉速率达到25.1mm/a。对昆明市地面沉降现象与古滇池松软的湖相沉积、局部地区的地下水资源长期超采以及该地区强震活动的因果关系进行了初步探讨。

The land subsidence in south Kunming,in the most of area south of the S econd Ring Road,is analyzed using the monitoring data of land subsidence in Kunm ing from 1979 to 1998.There are the two subsidence areas in shape of funnel in t he south Kunming;the one took Xiaobanqiao as the subsidence center with the sub sidence value of up to 227.5 mm(1985～1998);evident subsidence occurred in Zhuj iacun,Wujiaba airport,Guangweicun,Xiaosicun,Liujia and Guandu with the average rate of about 17 mm/a and the maximum subsidence of up to 30.0 mm/a;The other subsidence center was located in the area around Heweicun and Yunhucun north of Haigeng,with the subsidence value of up to 100.4 mm(1993～1997)and the subsi dence rate of 25.1 mm/a.Causal relation between the land subsidence in Kunming and soft lake deposit in Paleo-Dianchi,over-extraction of ground water for a lon g time in some areas and strong seismicity is preliminarily studied.
