| 摘 要： | 本文借助地理信息系统(GIS)技术,在数字高程模型(DEM)数据的基础上对重庆地区的实际日照时间空间分布规律进行了研究.结果表明:以分步式模式计算实际日照时间结果可靠;重庆市实际日照地区分布不均衡,差别较大;总体上,北多南少;南部地区是西多东少.

| Abstract: | Based on DEM, the distribution rules of real sunshine hours have been investigated by GIS in Chongqing. The results showed that the disparted step mode is reliable. The real sunshine distribution is very unbalanced in Chongqing. As a whole, the sunshine hours of the north is more than that of the south. Furthermore, the sunshine hours of the west is more than that of the east in the south region of Chongqing. |
