摘要
"精准农业"是基于农田内空间差异性信息和现代科学技术的作物生产管理系统。地理信息系统(GIS)是"精准农业"技术实践中的关键技术之一,它通过与GPS的结合,获取农田内空间差异性信息,建立农田环境要素信息数据库,运用GIS的各项功能对环境要素数据进行转换、处理和分析,最后形成各种指导农业生产的处方图形。该文以上海精准农业示范区为例,分析农田环境要素信息在GIS中的流动过程,信息流动主要环节的技术实现;空间插值方法是精准农业技术实现的重要方法,该文对常用于农田环境要素的空间插值方法做了初步研究。
Being one of the efficient methods for agricultural resource utilization, precision agriculture will not only improve the potentiality of cultivated land resources and the quality of agricultural product, but also will reduce the production cost and avoid environmental pollution resulted from agricultural activities. Therefore, precision agriculture is a good method for agricultural sustainable development. Precision Agriculture is an agricultural management system based on the modern science technology and the information of spatial difference in field. GIS, one of important technologies in 'Precision Agriculture', is combined with GPS to obtain the information of spatial difference in field and sets up the database of field information, and then forms the 'prescription' maps which can instruct the agriculture production. Taking shanhai's demonstration field of precision agriculture as an example, this paper analysis the flow process of field information in GIS. The method of spatial interpolation is an important technology in 'Precision Agriculture', this paper do primary research on several common methods of spatial interpolation.
