Solar Radiation Resources Applications in Agriculture Based on GIS in Ningxia YanChi

摘要

In order to exploit solar energy resources, and improve agricultural production and, this paper make a analyses and calculation about the distribution of direct solar radiation in in Yanchi country of Ningxia by using the geographic information system(ViewGIS3.0). In addition, we combined with meteorological data to ascertain the period of effectively using solar radiation resource for agricultural production in this area. in the area.
