摘要: 针对河南省内地表沉降问题,利用河南省地质信息连续采集运行系统(HNGICS)分析全省域内地表形变,对比时间基线为10 a的HNGICS基准站ITRF2014框架下三维坐标,获得河南省内三维速度场,分析河南省内地表形变规律与地质环境相关。结果表明:河南省内整体平面位移变化较小,平面变化10 mm以内的基准站16个,在10~20 mm之间的站点15个,整体趋势表现为由西向东,南部水平位移优势方向为东偏北方向30.7°,平均运动速率为0.87 mm/a;北部平原水平位移优势方向为东偏南方向82.6°,平均运动速率为1.6 mm/a,省域内地表存在明显的相对运动;竖直方向上,东部平原地区平均沉降速率为11.0 mm/a,山区平均沉降速率为1.4 mm/a,山区沉降速率远小于平原地区。

Abstract: In view of the surface subsidence problem in Henan province, the continuous collection and operation system of Henan province geological information (HNGICS) is used for the first time to analyze the surface deformation in the entire province. In this paper, three-dimensional coordinates under the framework of ITRF2014 of HNGICS datum station with 10-years time baseline are compared to obtain the three-dimensional velocity field in Henan province, and the laws of surface deformation in Henan province are analyzed, which are related to the geological environment.The results show that there is 16 reference stations within 10 mm and 15 stations between 10 mm and 20 mm in Henan province. The overall trend is taken from west to east. The dominant direction of horizontal displacement in the south is 30.70°,and the average velocity is 0.87 mm/a. The prevailing direction of horizontal displacement in the north plain is 82.60°.The rate is 1.6 mm/a and there is noticeable relative movement on the surface of the province. Vertical direction, the average settlement rate in the eastern plain area is 11.0 mm/a, and that in the mountainous area is 1.4 mm/a. The settlement rate in the mountainous area is much lower than that in the plain area.

Key words: HNGICS, surface movement, three-dimensional velocity field, the surface subsidence, groundwater overextraction
