Abstract: Based on data of the Chinese Meteorological Administration(CMA) from 1961 to 2008,the geographical coordinates of 155 meteorological stations and the global digital elevation map(GTOPO30,DEM),the author analyzed the spatial pattern of averagely annual sunlight and temperature,accumulated temperature over 10℃,annual precipitation and the precipitation of the four seasons in North China and obtained the climate resources pattern map.The results showed that the annual sunshine time was higher in northern than southern.The pattern of annual average temperature and accumulated temperature over 10℃ were that south was higher than the north and the east was higher than west.The tendency of the precipitation overall pattern from the north to the south was on the increase.The precipitation of the four seasons was unusual non-uniform and mainly concentrates in the summer.Generally speaking,heat resource and precipitation in the southern region was rich.While the light resource was relatively short.Light and heat resources in the northern region of North China were adequate,but the precipitation was the key limiting factor.

Key words: Annual average sunlight hours, Annual average temperature, Accumulated temperature over 10℃, Precipitation, Spatial pattern, North China
