Researching the relationships between the environmental change of vegetation and the activity of debris flows based on remote sensing and GIS

Abstract

Debris flow is a typical natural disaster, with a strong destruction role to human life and property and a great threat to the stability and harmony of human society. For researching the relationships between the environmental change of vegetation and the activity debris flows, this paper argues the main research should be the following, such as researching the impact of types change of vegetation cover on activity of debris flows, studying the impact of vegetation coverage change on the activity of debris flow, discussing time-space model of vegetation cover change impact on debris flow activity. The study of debris flow is the frontier crossing of multi-disciplinary. Application of advanced and mature techniques of RS and GIS for researching the relationships between vegetation cover change and the debris flow activity, it is high academic significance, important theoretical and social and economic significance. © 2011 Published by Elsevier Ltd.
