摘要: 利用华北山区气象站观测的温度与其所在纬度、经度和高度,分山区建立宏观地面气温场方程。采用1:20万地形图,以10'经、纬度为步长,判读其高度值,代入已建立好的方程中,经地形项订正,推算华北山区年、月平均温度、年较差和ΣT'≥10℃,其精度达极显著水平。计算结果使我们对华北山区热量资源有了新的认识,最后求算华北山区的主要水果最优品质种植上限高度。

关键词: 温度推算模式, 华北山区, 果树种植上限

Abstract: This paper makes use of the observational temperature data of the meteorological stations of the mountainous areas in North China and their respective latitude,longitude and altitude to establish a macro-earth surface temperature field equation for each mountainous area.Using the topographic map on the scale of 1:200000,and taking each 10'(longitude)×10'(latitude) as the step length,we inteapret the altitude value and place it into the established equation.After the topographic corrcction, the annual and monthly mean temperatures the annual range and the Σ t'≥10℃ of the mountainous areas in North China are calculated.The accuracy reaches a very notable level.The results make us gain a new recognition about the thennal resources of the mountainous areas in North China.Finally,the upper planting limits of the best species of the main fruit trees are calculated.

Key words: temperature calculation model, the mountainous areas in North China, the upper planting limit of fruit trees
