摘　　要：为准确提取郑州的地表形变信息,本文基于融合分布式目标的DS-InSAR技术,处理2019年1月—2023年12月的50景Sentinel-1A卫星影像数据,获得主城区的地面形变速率与累积形变量。结果表明,郑州中心城区尤其是地下水禁采区地表存在上升现象,主要沉降区位于郑州东区及中牟县。典型形变区域的分析表明,最大沉降区位于中牟县白沙镇,最大下沉速率约为20.0 mm/a,其他沉降区域则成点状分布于各乡镇与主要居民地。本文试验结果可对郑州的城市规划和建设提供准确的技术支持。In order to accurately achieve the deformation of the surface displacements of Zhengzhou city,the DS-InSAR technology fusing with high coherence points and distributed targets is employed with 50 Sentinel-1A images acquired from January 2019 to December 2023.And thus the annual ground displacements rate and the cumulative displacements are obtained in the main urban districts.The results indicate that the increasing districts are mainly located in Zhengzhou central area,especially in extracting groundwater in prohibited areas,whereas the settlement regions are distributed in eastern regions and Zhongmu county.And then the deformation in typical area is further analyzed,which shows that the serious sinking regions are located in Baisha town,Zhongmu county,in which the maximum subsidence rate is up to 20.0 mm/a.Furthermore,other sinking districts are scattered over the areas in various villages and towns.The investigation in this paper provides reference for the urban planning and construction of Zhengzhou.
