一、利用遥感技术预报泥石流的可能性 常规的方法研究泥石流对于广阔的山区是十分困难的。而利用遥感图象的宏观性、真实性和多时相多光谱等特点,有可能提高这种研究的速度,并在许多方面有常规手段所不及的优势。首先从战略意义上讲利用遥感图象结合气象资料,可以对较大区域中的泥石流作出概略的分区,其作法如下:因泥石流的发育与自然条件和人为因素密切相关,自然条件主要指
First, the possibility of using remote sensing technology to predict debris flow Conventional methods to study debris flow is very difficult for the vast mountains. The use of the macroscopic, authenticity and multispectral multispectral features of remote sensing images may increase the speed of such research and in many respects have advantages over conventional methods. First of all, from a strategic sense, the use of remote sensing images combined with meteorological data, debris flow in larger areas can make a rough zoning, its practices are as follows: Due to the development of debris flow and natural conditions and human factors are closely related to the natural conditions mainly
