利用 CORS 站网监测温州⁃丽水区域环境负荷 对地壳垂直形变和重力变化的影响.

Based on the comprehensive calculation of CORS network, this paper uses the load field removal‐ recovery technology to study the crustal vertical deformation and ground gravity spatio ‐ temporal changes caused by environmental load in Wenzhou ‐Lishui region and compares it with GRACE gravity satellite results. Some conclusions are drown as follows: ① The effects of environmental load on the vertical deformation and gravity change of crust are up to the centimeter and ten micro ‐gauge levels, respectively, and the seasonal variation characteristics are significant. ② The vertical deformation and gravity change in winter show a decreasing and increasing trend from west to east, respectively. ③ Compared with GRACE results, in addition to local region differences, the overall trend of spatiotemporal changes has a higher consistency. ④ The CORS network can monitor the spatiotemporal changes of crustal vertical deformation and gravity field caused by total surface environmental load. The research methods and results of this paper can provide an important reference for environmental dynamics research and geological disaster monitoring and early warning. [ABSTRACT FROM AUTHOR]
