Spatial Distribution Of Solar Radiation And Temperature Over Mountainous Area Of Qinling

In this paper, a research of spatial distribution of solar radiation and temperature over mountainous area of Qinling is presented. The research is based on monthly mean temperature and sunshine ratio data of 36 meteorological observe stations over Qinling zone in 1971-2000, and Xian solar radiation data in 1961-2000, and 1km × 1km DEM data over Qinling zone. Using mountainous climate theory and GIS technology, a series of radiation spatial distribution models has been set up, and the spatial distribution over Qinling zone has been calculated. By analysis of factors which influence temperature spatial distribution over Qingling zone, the model of spatial distribution of mountainous monthly mean temperature has been estimated , the spatial distribution over Qinling is given.
