京九铁路赣南段沿线地区水土流失特征遥感分析

APPLYING REMOTE SENSING TECHNIQUE TO ANALYSE SOIL EROSION FEATURE OF GANNAN AREA ALONG THE JINGJIU RAILWAY

京九铁路赣南段沿线地区是我国南方水土流失最严重地区之一，也是我国南方一个典型的水土流失区。本文根据遥感调查结果，较详细地论述了该区水土流失的类型、分布特征、发展趋势，并分析了水土流失产生的原因及其造成的危害，以便为京九铁路沿线地区的经济开发。

Gannan in one of the most serious and most typical soil erosion area where Jingjiu railway pass through. Based on the result of remote sensing investigation, this paper discussed in detial soil erosion's types, the distribution feature as well as its development trend. The cause of soil erosion and its dangerious to Jiangjiu railway was analyzed, so it can provides the scientific basis for economic development, territory harness and evironment evalution.
