摘要
运用In SAR技术开展珠三角地面沉降监测,研究其产生的机理、发展趋势和防治措施,就该区运用In SAR技术进行监测获取地表沉降动态结果,进一步研究了在植被覆盖密度大及水网密布区域开展In SAR监测的规律和特性,验证了监测结果的可靠性,分析了地表沉降的主要原因。
In this paper,InSAR was used to obtain the dynamic results of land subsidence in the Pearl River Delta.And then,the regularity and characteristics of using InSAR to monitor in the area with high vegetation coverage and staggered water network were studied and discussed further.At last,the reliability of the monitoring results was verified and the main causes of surface subsidence were analyzed.
