基于3S技术的国家级农情监测系统
RS-GIS-GPS-Based Agricultural Condition
Monitoring Systems at a National Scale
摘要
Abstract
China has a large population and limited arable land. It is es sential to monitor agricultural condition, mainly annual farmland variation, cro p condition and forecast grain yield for government decision making. In recent y ears, information technology has made considerable progress and 3S technology, R emote Sensing, GIS and GPS, have been used for resources and crop monitoring at a national or global scale. 3S technology based on agricultural condition monit oring systems at a national scale is introduced in this paper.关键词
