摘要
在对黄山松分布区的气候因子进行全面收集和调查,初步确定其分布范围和适生条件的基础上,对分布区内黄山松垂直分布下限的气候因子进行了相关分析,阐明了热量、日照以纬向变化为主,降水量呈经、纬双向变化的规律。同时,利用6项主要气候因子的主成分排序,把黄山松分布区划分为台湾区、南部区、西南部区、东南沿海区、中西部区、东北区和北部大别山区等7个气候生态区。
The horizontal and vertical distribution limits of Pinus taiwanensis were determined. Through correlation analysis of the climatic factors in the lower limit of the vertical diatribution area we found that the temperature and sunshine hours vary mainly with the latitude, whereas rainfall differs with both the longitude and the latitude. According to the results of principal component analysis, the distribution of P. taiwanensis is divided into 7 sub—areas based on 6 items of climatic data, namely, Taiwan sub—area; south sub—area; southwest sub —area; southeast coastal sub—area; west central sub—area; northeast sub—area; and north sub—area.
