应用正态型分布贴近度对山楂引种区的分析

Analysis on Introduced Area of Crataegus pinnatifida Bge. by Applying Normal Distribution Approach

河北兴隆是山楂适生区 ,本文应用正态型分布贴近度 ,分别计算出松山区 5个气候区气候因素与兴隆相应气候因子的贴近度和兴隆、松山区两个地区相应气候因子上的总贴近度 ,由择近原则识别出松山区各气候区气候因素对兴隆相应气候因素贴近顺序 ,为引种山楂提供了科学依据。

Xinglong in Hebei Province is an area suited to plant Crataegus pinnatifida Bge. In this paper, approach of climatic factors in five climatic regions in Songshan District relevant to Xinglong and the general approach of relevant climatic factors in Xinglong and Songshan have been calculated. The approach sequence of climatic factors in these two districts has been decided with law of choosing approach.
