摘要: 基于西藏自治区沙漠化普查数据库和图库,研制西藏自治区沙漠化地理信息系统,建立起“图形-属性”、“属性-图形”双向链接互通功能。系统具有主视图、属性表、统计图表、和图版等功能。利用GIS的存储、查询和地理分析功能研究沙漠化的现状,了解沙漠化危害程度,预测沙漠化发展趋势及规划防沙治沙措施等具有十分重要的意义。而将GIS应用于计算机制图、荒漠化指标体系的建立、荒漠化监测等工作中,将西藏沙漠化研究推向一个新的高度起到重要作用。

Abstract: The data and image base on general desertification survey for Tibet was used to design the Xizang Desertification Geography Information System(XZDGIS), by which a retrieving function whether from spot to data or from data to spot has been established. The XZDGIS system comprises Views, Tables, Chart and Layout. Former research results showed that common GIS system, based on its functions of storage, inquiry and geographical analysis, has very important significance in studying desertification status, knowing its endangering degree, predicting its developing trend and planning the controlling measures etc. Moreover, I suggest that the application of GIS in computer cartography, in the establishment of Desertification Index System, and in the monitoring to desertification dynamics, has pushed the desertification research to a new high.

Key words: Tibet, desertification, GIS, Arc/Info, Arc/View
