| 摘 要： | 岩溶塌陷是岩溶发育地区所特有的灾害地质现象。它随着人类的经济活动的频繁而加剧。在我国,可溶性岩石覆盖了全国三分之一强的面积,因此,岩溶塌陷的防治和预测则格外重要。对岩溶塌陷进行探测,遥感技术是一个有效的方法。航空摄影是最常用的,其解译规范已建立了。热红外扫描技术在一些调查中也是很好的方法,这种方法关键应测得地物的温度,并选择合适的飞行高度。卫星影像解译结合实地调查是进行塌陷预测和调查塌陷分布的一种辅助方法。

| Abstract: | Collapse is a typical geologic disaster in karst area. The collapses are increasing with the intensity of the man's economic activities. Soluble rocks cover a area about one third of China, therefore predicting and managing of the karst collapse are taken to be a serious matter. Remote sensing techniques area significant method of detecting collapse. Within these techniques, visible aerial photography is the most common, and various criteria of interpretation have been set up. Thermal infrared scanning technique could also be a considerable method in the special investigation, but the surface temperature of the target needs to be measured in the field for several days and The flight altitude is selected appropriately. Satellite imagery interpretation is a assistant method associated with ground investigation on predicting collapse and studing the region distribution of collapse. |
