摘要
地理信息系统(GIS)及其应用技术近年来发展迅速。作为一种空间信息分析技术,它在农业的应用中发挥着技术辅助的作用。GIS技术可以有效地管理具有空间属性的各种农业资源环境信息,对其管理和实践模式进行快速和重复的分析测试,便于农业开发项目选址、决策、进行科学和政策的标准评价,还能方便地对多时期的项目环境状况及生产活动变化进行动态监测和分析比较,明显地提高农业开发项目的经济效益,避免项目重复申报、面积不足等短视行为;进而趋利避害,维持高效可持续发展。
Geographic information system （GIS） and its application technology is developing rapidly in recent years.As a kind of spatial information analysis technology,it plays technology support in the application of a- gricuhural.GIS technology can effectively manage all kinds of agricultural resources and environment with space attribute information ,the management and practice mode for rapid and repeated analysis test ,facilitate agricultural project site selection ,decision ,the standard of science and policy evaluation, also can easily environmental condition and production activities of many periods of project change dynamic monitoring and anal- ysis comparison,obviously improve the economic benefits of agricultural projects,to avoid repeating declaration,project area is inadequate shortterm behavior;And avoid disadvantages,to maintain efficient and sustainable development.
