基于3S技术的智慧农业研究进展

A Review of Wisdom Agriculture Based on 3S Technologies

智慧农业是智慧地球的重要组成部分,它将成为我国现代农业未来的发展趋势,以遥感、地理信息系统、全球定位系统为一体的3S技术为智慧农业的实现提供了技术支撑。本文在对国内外相关文献资料分析研究的基础上,首先探讨了遥感技术(RS)在智慧农业中土地资源信息、作物长势信息和作物生态环境信息的采集和作物产量估产、灾害损失评估中的应用。然后分析了地理信息系统(GIS)在智慧农业中信息存储、分析和智能化处理方面的应用,着重研究了农田信息可视化与专题图制作、农业信息空间分析与建模、田间管理智能决策等应用。其次又对卫星定位(GPS)技术在智慧农业中空间和时间定位、土地更新调查、监测作物产量等方面的应用进行了探讨。最后,针对3S集成技术在智慧农业中的应用进行了总体分析研究。

Wisdom agriculture is an important part of the wisdom Earth, it will become the future development trend of China＇s modern agriculture.The integration of 3S technologies, including Remote Sensing, Geography Information System,Global Positioning System, has provided technical support to achieve wisdom agriculture. Based on the analysis of relevant literature at domestic and abroad, firstly we discuss the application of Remote Sensing（RS）, which is used in the wisdom agriculture containing land resource information, crop condition information, eco-environment information collection and estimating yield of crop, disaster losses assessment. After that, we analyzed the application of Geography Information System（GIS） in wisdom agriculture including information storage, analysis and intelligent extraction, especially focusing on the visual implementation of field information and making thematic map, spatial analysis modeling of agricultural information, and intelligent decision for field management. And then the Global Positioning System（GPS） application in wisdom agriculture about spatial and temporal positioning, land updated survey, and monitoring crop yield are discussed.Finally, we proceed to a discussion about how 3S integrated technologies can be used in the wisdom agricultural applications at an overall analysis.
