农业遥感技术应用现状

农业是遥感应用中最重要和最广泛的领域之—。农业遥感技术是集空间信息技术,计算机技术,数据库、网络技术于一体,通过地理信息系统技术和全球定位系统技术的支持,在农业资源调整、农作物种植结构、农作物估产、生态环境监测等方面进行全方位的数据管理,数据分析和成果的生成与可视化输出,是目前一种较有效的对地观测技术和信息获取手段。20多年来,遥感技术在农业部门的应用也越来越广泛,完成了大量的基础性工作,取得了很大的进展,在农业资源调查与动态监测、生物产量估计、农业灾害预报与灾后评估等方面,取得了丰硕的成果。

Agriculture is one of the most important and sprending fields in practical Romote Sensing. Agricultural technology of Romote sensing in tegrates spacial information technology, computer technology, with database and network technology and omnibearingdata management, data analysis and fruit making are operated in agricultural resource adjestment, crop planting structure, production estimation, ecological environment monitoring and so on, based on systems of geographical information and global orientation. It is also an effective technique of observing earth and method of obtaining information atpresent. R^aote sensing applied to agriculture has become more and more spreading, has carried out a mass of fundamental work and has gained tremendousprograss and harvest, especially, in agricultural resource investigation, dynamicmonitoring, production estimation, disaster report and loss estimation.
