基于植被供水指数的桂西北旱情遥感监测研究与应用
Study and application of Northwest Guangxi drought remote sensing monitoring based on vegetation supply water index
摘要
Abstract
In view of frequent extreme weather,drought increasing and being more and more serious,Northwest Guangxi was studied. Remote sensing images of different periods were collected. Based on analysis of image indexes such as vegetation and temperature,grading rules of vegetation supply water index was determined according to his⁃torical drought information. In accordance with the rules,real-time and dynamic drought information monitoring is possible. The achievements of study may strengthen drought alarm capability and provide technical basis for drought prevention and protection.关键词
