摘要
利用航空遥感方法对云南省澜沧－耿马地震灾情进行调查，对震区的震害特征、房屋破坏、山体崩落和滑坡等进行定量量测、统计和分析。在统计房屋倒塌率的基础上绘制了澜沧－耿马地震区房屋倒塌程度分区图、澜沧－耿马地震区山区崩落体分布图。据航片统计量测，在摄影区范围内房屋倒塌６５００余栋；崩落体３９２处，其中最大的石佛洞至金列段崩落体土石方量达１６４万ｍ３。调查结果表明，用航空遥感方法进行地震灾情调查是十分有效的。
The earthquake disasters in Nanchang-Gengma epicenter area, which mainly were the crashed houses and the rockslides, were surveyed by airborne remote sensing. 6500 crashed houses were interpreted and 392 rock slides were measured with the aerial colour infrared film. The biggest rock slide in earthquake area,located from Shifudong to Jinglie in Gengma county, was about 1.64× 106m3. According to the statistics of the crashed houses and the rock slides, the degree of the crashed houses and the distribution of the rock slide were charted respectively. The results show that the earthquake disaster can be surveyed accurately by airborne remote sensing in a short period of time after shock.
