摘要
The high accurate gravity measurement have been carried out many years in the capital region. The main characteristics of the change of gravity field during the latest eight years (1981 - 1988) in the region are presented inthis paper. The more gravitational variation appeared in the southern and south-eastern part, the maximum variation come to 10-6 ms-2. In the northern part, for instance: Chengde City, and Wan-clan County - westTaihang mountain area which are in the westside of the network, were relative stable. The noticeable areas ofgravitational variation were in Tianjin-Baxian-Renqiu which correspon d with the crustal vertical deformation.The main cause of that is related to pump ground water and petroleum.
