摘　　要：为了对无资料地区的温度分布及热量时空分布状况进行详细推算 ,对以往的小网格气候订正公式进行了改进 ,引入不同季节太阳高度角对坡面辐射的影响 ,并用线性内插确定界限温度的初终日期 ,以利用逐旬气候资料进行小网格订正 ,从而得出了红寺堡、兴仁堡、清水河中下游及罗山东鹿网格点温度分布 ,形成了包括年、季、月、旬温度场 ,各界限温度初终日期、持续日数及积温场小网格数字化图集。By considering the radiation influence of different solar angle in different season, a new way were developed to improve the method of small grid, in order to estimate the distribution of the temperature and quantity of heat resource in the region without weather statistics in details. We also obtained the begin date and end date for some confines of temperature by linear interpose, so that we can use the data for each period of 10 days to estimate by the method of small gridding and can do our work better in profundity and particularity. As a result, we estimate the distribution of the temperature in Hongsibu, Xingrenbu, area of Qingshui River and piedmont of the Luo Mountains. The numeral atlas obtained includes the distribution of the temperature for different period of times, begin date and end date for some confines of temperature and the period of days etc.
