一种基于MODIS遥感技术的泥石流影响因子新测量方法

现有泥石流预报方法多侧重于通过分别测量影响泥石流发生的多个主控因子和触发因子，从中寻找预报泥石流发生的征兆，并结合适当的模型来初步预测泥石流的发生．本文借助MODIS卫星遥感技术在探测地物方面的优势，改进了对影响因子的原有提取方法：针对影响泥石流爆发的各种因子的内在联系，首次提出用植被指数代替植被覆盖率和植被含水量2个因子进行联合测量，较好地考虑到了两者之间的内在联系和测量的便利性．并通过对都江堰地区和华南地区2个区域的测量初步检验了这一方法．

A New Measurement to the Influence Factors of Debris Flow based on the MODIS Techniques

It is believed that most of the forecasts about debris flow tend to measure the key factors and toggle factors respectively and fill these factors incertain model to calculate the final result in the field of objects monitoring,The formerindce-factors extrncting measures are improved in this paper.It first put forward to measure vegetation index as United Measurement of the vegetation covering rate and vegetation aquiferous rate to take account of the inner connection between the two rates above.And this as...
