数字农业——数字地球的应用之一

This paper describes the concept and contents of digital agriculture, its current status and davelopment trend The information technology, spatial technology, and micro-electronics technology make a revolution to traditional agriculture It is based on cultivation of big farmland, using advanced technology as background It is an agriculture technology system with the characteristics of integration and information It means that whole procedure of the cultivation, semination, irrigation, fertilizer, farmland management, protection of forestry, estimate of product, store, and administration will be characterized by digital, network, and intelligence, using technology of remote sensing, telemetry, tele-control, and computer in order to make every square meter have optimized using It will constitute an information agriculture technology system for monitoring and estimation of crop, caltivated area, and soil, current or dynamics analyses of crop growth, and factors of environment, diagnose forecast, cultivation step, management planning and decision support We first describe the application of remote sensing and telemetery in agriculture forecast, then introduce GIS, GPS, and automatic agriculture device, finally give the component of digital agriculture system $$
