PRECISION AGRICULTURE AND ITS PROSPECTIVE IN CHINA
试论精确农业及我国行动对策

Precision agriculture is one of the most advanced technologies in agriculture. Its marginal efficiency in economy and environment is significant, since it makes full use of temporal and spatial variabilities of crops, soils, insect pest and disease to farming practices and field management. According to China's conditions, it is not only necessary but also feasible to study and develop appropriate technical and applied systems of precision agriculture. The development of precision agriculture will facilitate solutions to major issues in population, resources and environment and benefit China in high efficiency utilization of agricultural resources and environmental protection. To meet the specific requirements of precision agriculture, some adaptations, like those in interface, statistical and modeling functions, easy manipulation, information resources, real time GPS connection, and processing speed, should be made on GIS, which is the key technical system in integrated precision farming practices.
