采用经纬度、海拔高度、年降水量、年活动积温、温暖指数(W_I)、寒冷指数(C_I)、干燥度指数(K)和湿度指数(H_I)等对福建省植被地带性分布规律进行定量解释,并首次引入极端最低气温等进行综舍研究.通过主成分分析得出限制福建省地带性植被生长的主导环境因子是水热状况因子、地理位置因子、降水因子和极端温度因子等4个指标;以主成分得分作为划分的指标,经过系统聚类,结合<福建省植被图>,将福建省植被带划分为9个区,并对各分区的气候、植被特点进行描述.

The zonal distribution of vegetations in Fujian Province was evaluated quantitatively by means of indexes, including longitude, latitude, altitude, annual precipitation, active accumulated temperature, warmth index W_I), coldness index (C_I), aridity index(K) , humidity index(H_I) , and dominant environmental factors. Extreme minimum temperature was applied to the distribution study of zonal vegetations for the first time. Results of principal component analysis indicate that the main factors limiting the distribution of zonal vegetations in Fujian are water-thermal factors, geographical position,precipitation, and extreme minimum temperature. The vegetation distribution in Fujian could be classified into nine zones according to the cluster analysis and the " Fujian vegetation map". And the vegetation and climate characteristics of each zone are also described.
