天津市控制地面沉降分区管理模式研究

The Grading Management and Mode Research on the Control of Tianjin Land Subsidence

天津市平原区出现了不同程度的地面沉降现象,全市年均沉降速率约30mm,地面沉降造成的经济损失很大。本文采用分类赋值打分的方法,利用ArcGIS软件进行后期处理绘制天津市地面沉降分级管理区域,并提出相应的控沉管理措施。

There are the phenomena of land subsidence at different degrees in Tianjin plain areas,and the average annual subsidence rate is up to 30mm in the whole city.So,the land subsidence has caused great economic losses.This paper has 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 for Tianjin city.
