地面塌陷特征及其遥感识别方法研究

地下矿产资源的开采会引发地面塌陷，这已成为严重制约矿区可持续发展的重要因素。其主要表现形式有：塌陷盆地、塌陷坑、地裂缝、滑坡崩塌等，并引发道路污染和道路改线及居民地和水系的变化。在矿山开发多目标遥感调查与监测过程中，这种地质灾害现象较为突出。本文在总结了地面塌陷的主要类型及其特征的基础上，对塌陷地的遥感识别方法进行了分析和研究。

CHARACTERISTIC OF LAND COLLAPSE AND ITS IDENTIFICATION METHOD IN REMOTE SENSING IMAGE

The underground resource exploitation may cause land surface collapse, which has becoming an important factor to restrict the sustainable development of the mining area. The general form of its display includes： collapse basin, collapse pit, ground fissures, landslide, and landslip etc. They make road polluted and compel road to change position, cause Residents and water system to change. In the course of multi target remote sensing investigation and monitoring of mine resource exploitation, this kind of geological hazard phenomenon is very common. The author analyzed and studied the identification method of land collapse in remote sensing image based on the summarizing main types and characteristics of the land collapse.
