【Abstract】 Surveying the distributive characteristics of the heat resources in the Taihang Mountain Area in Hebei Province, authors knew priliminarily the mean annual temperature, mean temperatures of the hottest and coldest mouthes, the frostless season and the geographic distributive regularity and varying characteristics with time for the soil temperatures. Moreover, authors analysed the heat conditions in the crop growing period and the influences on crops.更多还原
