摘　　要：应用国家气象局整编的华北地区155个气象站点48a(1961-2008年)的气象资料和中国数字高程模型,对华北地区48a日照时数、年均气温、≥10℃积温、年降水量和春、夏、秋、冬四季降水量等气象资料的空间分布进行分析,得到了华北地区气候资源分布图。结果表明:华北地区年日照时数总体分布为北高南低,气温及≥10℃积温分布为南部高于北部,东部高于西部,降水总体是从南向北递减,四季降水不均匀,主要降水集中在夏季。总体来说,华北南部地区热量及降水资源丰富,而光照资源相对较少;华北北部地区光照和热量资源充足,降水资源相对短缺。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.
