摘要
论文以南昌市主城区为研究区域,采用PS-InSAR技术获得研究区域的地表沉降数据,并收集整理18个可能与地表沉降相关的影响因子,采用灰色关联分析模型(GRA)进行数据相关性分析,从统计学角度解释影响因子与沉降速率间的相关性。经分析表明,南昌市地表形变是自然因素与人类活动因素共同作用的结果,且自然因素大于人为因素。
The main urban area of Nanchang is taken as the study area,and the ground subsidence data of this area are obtained with PS-InSAR technique.18 possible factors related to ground subsidence are collected and sorted out.Then the data correlation analysis is carried out by using the gray relational analysis model(GRA).The correlation between impact factors and subsidence rate is explained statistically.The analysis shows that the surface deformation in Nanchang is the result of the jointaction ofnaturalfactors and human activities,and the contribution ofnaturalfactors is greater.
