Abstract:An objective and high resolution and full digital and real time monitoring meteorological 3S system, which provides the functions of GPS, RS and GIS data real time collecting, rectifying, retrieving, multi sources space data synthesis analyzing and dynamically monitoring, is developed for agricultural region division, agricultural economic adjustment and ecological environment construction supported by RS, GIS and GPS technology. The transformation from the traditional qualitative, individual spot and static analyzing of Ningxia climate, land resource and remote sensing information into the quantificational, positioning and dynamically precised evaluating is achieved, and the goal of reasonable exploitation, the balanced use and the sustainable development of Ningxia basic resource is primarily realized.
