基于遥感技术的采煤塌陷区时空演变研究

目的]为采煤塌陷区检测工作提供依据。方法]利用遥感技术解译塌陷区整治前后的遥感图像,以获取塌陷区时空演变信息,定性分析采煤塌陷区综合治理的成效。结果]塌陷区整治后,唐山市南部塌陷区和粉煤灰的面积逐渐减少,绿地面积不断增加。结论]塌陷区综合整治有利于恢复生态环境和自然景观,对区域发展具有积极意义。

Research on Spatial-temporal Change of Coal Mining Subsidence Area Based on Remote Sensing Technique

Objective] The aim was to provide reference for the detection of coal mining subsidence area.Method] The remote sensing images of subsidence area before and after treatment were interpreted by adopting remote sensing technique,so as to acquire the spatial-temporal change data of the area and analyze the effects of the comprehensive treatment qualitatively.Result] After the treatment of subsidence area,the area of subsidence region and fly ash region in the north of Tangshan City was decreasing gradually ...
