摘要
针对地壳垂直形变受多力源影响 ,单一逼近模型难以准确逼近地壳形变场的问题 ,提出了两步逼近综合模型和加权综合逼近模型 ,给出了模型应用实例并进行了验证。结果表明 。
Due to the complex and multi power factor characteristics of vertical crustal movement, it is not effective to approximate the velocity field by simple model. In this paper, we propose two integrated approximation models:two step combining model and weighted combining model to approximate the vertical crustal deformation field. We have approximated the vertical deformation field of Bohai Gulf with these two models and obtained some satisfactory results.The results imply that the methods proposed in this paper have the theoretical and practical values.
