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。 Karst collapse is a special geological disaster in karst areas. It is exacerbated by the frequent economic activities of humankind. In our country, soluble rocks cover over one-third of the country’s area. Therefore, prevention and prediction of karst collapse are especially important. To detect karst collapse, remote sensing technology is an effective method. Aerial photography is the most commonly used and its interpretation specification has been established. Thermal IR scanning is also a good method in some surveys. The key to this method is to measure the temperature of the feature and select the appropriate altitude. Satellite image interpretation combined with field surveys is an adjunct to predicting collapse and investigating collapse distribution.
