摘要
应用温暖指数分析了福建主要引种树种分布与热量之间的关系 ,结合半峰宽原理确定了福建省主要引种树种的最适热量分布范围。结果表明 ,天竺桂、少叶黄杞、闽楠及拟赤杨等树种是福建广域分布的引种物种 ,具有较宽的WI值 ;美蕊花、贝壳杉及红花天料木等树种的分布区域窄小 ,WI值的分布幅仅 7~ 1 0℃·月 ;南洋楹、凤凰木及木棉等热带、南亚热带树种具有较高的WI值 ,仅能在闽南一带引种栽培。主要引种植物的热量分布特征为其引种区域规划提供理论依据。
By applying the warmth index the analysis on the relationship between distribution and calorcity of the main introduced species in Fujian province was conducted, which would help to determine the best domain of calorcity distribution of the main introduced tree species through combination with the principle of peak width of half height. The results showed that some tree species such as Phoebe bournei, Cinnamomum japonicum, Engelhardtia finzelii and Alniphyllum fortunei(Hemsl.) etc. are the introduced tree species of wide distribution in Fujian with wide WI value. While the distribution area of Calliandra surinamensis, Agathis dammara and Homalium hainanense is narrow and small, whose distribution breadth of WI value is only 7~10℃/month;some tropical and subtropical plants, such as Delonix regea, Albizia falcataria and Bombax ceiba etc. have higher WI value, which can only be introduced and cultivated in southern Fujian. The calorcity distributions of the main reforested species will provide the theoretical basis for district programming of introduced species.
