摘要

There are the phenomena of land subsidence at different degrees in Tianjin Plain areas, and the average annual subsidence rate is up to 30 mm in the whole city. So, the land subsidence has caused great economic losses. This paper adopted the classification assignment scoring method by the ArcGIS software post-processing to draw the Land Subsidence Grading Management Area, and proposed the corresponding management measures to control land subsidence in Tianjin City.
