GIS在旱灾研究中的应用现状与前景展望

THE USAGE OF GIS IN DROUGHT RESEARCH OF CHINA AT PRESENT AND IN FUTURE

旱灾是我国最严重的自然灾害之一,它影响面广大,并且涉及内容复杂,研究困难较大.地理信息系统(GIS)具有强大的空间地理信息管理与分析功能,地理信息系统(GIS)可在处理遥感(RS)技术实时、动态地获得的各种信息方面发挥优势,通过GIS与RS的集成,建立旱灾的监测和预报系统,从而为防灾减灾提供决策依据.本文通过简要介绍国内一些GIS应用于旱灾研究的实例,对其中一些主要的应用状况和技术方法进行了总结归纳,并且对GIS在这一领域的应用前景进行了展望.

Drought is one of the most serious natural calamities in our country. There are lots of problems on the drought research, because drought is a complicated system. GIS as a new technology with the powerful functions of conducting information has been used in various parts of the society. The following passage is mainly talking about the present usage of GIS in the research of drought in China. In order to introduce clearly, we has quoted several samples and has made an conclusion at the end of the article.
