遥感技术在农业科技服务领域的应用

Application of remote sensing technology in agricultural science and technology service

【目的】遥感技术具有大范围、周期性获取地表信息的特点,被广泛应用于农业作物面积制图、农作物长势监测与产量估计和农情监测等农业生产和管理的各个环节。【方法】在阐述了地块级、业务化的农业遥感服务概念和内容的基础上,分析了国内外地块级、业务化的农业遥感服务现状。【结果】由于中国实行农民联产承包责任制,地块较为破碎,管理较为精细,对地块级遥感监测的需求不大等原因,使得中国地块级、业务化的农业遥感服务尚处于起步阶段。【结论】随着中国逐步推广农村土地流转,实施大范围的机械化农业,业务化、精细化的农业遥感监测具有广阔的前景。

【Objective】Remote sensing technology can obtain surface information in a large scale and periodicity.It is widely used in various aspects of agricultural production and management,such as crop area mapping,crop growth monitoring,yield estimation and crop monitoring.【Methods】This paper expounds the concept and content of land level and operational agricultural remote sensing service,and analyzes the present situation of land level and operational agricultural remote sensing service in China and abroad.【Results】Agricultural production contract system is implemented in china.This leads to the fragmentation of crop plots in China.And the production management is relatively fine.Therefore,there is little demand for land level and operational remote sensing monitoring in china.For these reasons,land level and operational remote sensing monitoring is still in its infancy in china.【Conclusion】With the gradual promotion of rural land transfer in China and the implementation of a wide range of mechanized agriculture,business and refinement of agricultural remote sensing monitoring has broad prospects.
