利用重力场模型对中国陆地和岛礁 GNSS水准沉降进行分析

摘要

利用现势性很强的EGM2008，EIGEN－6C，EIGEN－6C2，GO＿CONS＿GCF＿2＿DIR＿R4共四个地球重力场模型，对中国沿海近岸陆地和岛礁上16个区域的1053个GNSS水准点进行了沉降分析，最后发现中国沿海浙江省、辽宁省、上海市、天津市、广西、琼州北（琼州海峡北）、琼州南（琼州海峡南）7个区域存在沉降。%The current situation good EGM2008, EIGEN-6C, EIGEN-6C2, GO_CONS_GCF_2_DIR_R4 a total of 4 earth gravity field model, on 1053 GNSS benchmark 16 regionalChinese near shore coastal land and islands on the settlement analysis , finally found Chinese coastal Zhejiang Province , Liaoning Province , The city of Shanghai , The city of Tianjin , Guangxi Province , North of Qiong-zhou ( The North of Qiongzhou Strait ) , South of Qiongzhou ( The South of Qiongzhou Strait ) there are 7 areas of settlement .
