摘要
为了得出山区温度场的空间模式,本文选用代表站资料进行三元(纬度、经度和海拔高度)线性回归。对全国范围,九个省(区)和广西六个河谷流域片的气温场立体模式都进行了统计分析。这些回归分析结果充分证明了这一方法有广泛的用途,不仅能明确显示不同尺度范围热量资源的空间分布规律,对比地形影响,而且极大地有利于克服山区气候研究中经常遇到站点稀少资料不足的困难。
In this paper, the data of air temperature at selected stations were used in a three variable(latitude, longitude and A. S. L. )linear regression analysis to derive the spatial model of temperature field in moutainous areas. The spatial models of climatic heat resources throughout China, in nine provinces, and six river valleys of Guangxi were statistically analysed. The results of regression analysis proved that this method would be widely useful. The spatial distribution laws of heat resouces in different scale areas could be shown, and the geographic effects could be compared. It is helpful to overcome the difficulty that often occurs in studying mountain climate due to the sparseness of network and the lack of available data.
