Abstract:

Lancang River Basin is a typical mountain ecology system.With the cooperation development of the basin,mountain ecology system in this area is destroyed easily.Forest cover is a key fact about region environment changes resulted by human action.Monitoring forest cover is very important for sustainable development of Lancang-Meigong international river.The main purpose of this study is to develop a monitoring methodology to acquire forest cover in mountain area of Lancang River Basin.Study results show that:the approach of monitoring forest cover in mountain area based on NDVI process such as in this study is of well practical value.This methodology is simple and the process is easy performed.Accuracy of monitoring forest cover satisfied the need of the cooperation development of Lancang River Basin.The methodology is suitable to apply in this mountain area.
