Because of modis predominant space and spectral differentiate rate, it ’ s has been broadly applied to various field, in the aspect of snow monitoring, modis has been successfully using a normalized difference snow index ( ndsi ) to provide global automated binary maps of snow cover. the ndsi is a spectral ratio that takes advantage of the spectral difference of snow in short - wave infrared and visible spectral bands, although it has higher precision, it can only discern one pixel to snow or other features, can not satisfy accurate drainage basin snow cover mapping and snow parameter extracting
Modis數據因其優越的空間解析度、波譜解析度，已被廣泛的運用於各個領域，在積雪監測方面，已成功地運用歸一化差分雪蓋指數（ ndsi ）製作每天的全球雪蓋分布圖， ndsi是基於雪對可見光與近紅外波段的反射特性和反射差相對大小的一種測量方法，然而它只能將一個像元辨別為積雪或非積雪，滿足不了高精度應用要求。 -
Therefor, in the light of theory and methods of karst hydrogeomorphology and the knowledge of transformation, balance and variation of matter and energy in karst drainage basin, we can examine stone forest within a specific scope of time and space, and reveal the mechanism and the development model of stone forest with the help of the principle of the mutual response processes among base - level, water flow and forms. just based on the understanding above, the paper, with a special reference to the lunan stone forest which is the best developed one in china, discusses the hydro - geomorphlogical structure of the bajiang river, geomorphological types and spacial distribution feature of the stone forest, and studies the erosion rate on the top of stone forest, soil erosion rate, sub - soil dissolution rate and their combined influences on the evolution of stone forest, furtherly brings forward and demostrates the " tri - level erosion " mechanism for the development of stone forest
