【摘要】 近年来,由于地下水的大量开采,导致昆明市地面沉降日益严重,要想有效扼制地面沉降的速度,必须加大地面沉降的监测力度与提高监测精度。基于昆明市地面沉降的机理分析,传统的监测方法已经不能满足当前监测工作的要求,建立以3S技术为基础的GIS自动监测系统来获取高精度的地面沉降信息,并对地面沉降进行实时监控,是目前城市沉降监测的主要方法之一。在此基础上,分别阐述了GPS、RS及GIS技术在地面沉降监测中的应用,以及三者结合的作用,并对利用3种技术整合监测系统开展昆明市地面沉降监测的前景进行了展望。更多还原

【Abstract】 For recent years,because of massive mining groundwater,as leads to Kunming land subsidence to be serious day by day.In order to restrain the land subsidence speed effectively,the monitoring is basic automatic monitoring which must enlarge the subsidence monitor dynamics and the precision.This paper is based on the analysis of land subsidence mechanism of Kunming city.At present,the traditional monitoring method could not satisfy the current monitoring task requirement,to establish automatic monitoring system is based on the 3S technology union.In order to gain the high accuracy land subsidence information,and carried on the real-time monitoring to the land subsidence,it could satisfy the monitoring need of the city subsidence.The paper not only elaborates GPS,RS and GIS technology,separately,but the synthesis effect as well.The foreground of using three kind of technical union monitoring system to develop the Kunming surface subsidence monitoring is prospected.更多还原
