Vegetation zones and 10 vegetation types were classified using TWINSPAN and DCA: Bischofia javanica‐Machilus japonica var. kusanoi type on Ficus‐Machilus zone; Engelhardia roxburghiana‐Castanopsis cuspidata var. carlesii type on Machilus‐Castanopsis zone; Rhododendron formosanum type and Pasania kawakamii‐Machilus thunbergii type on Quercus lower zone; Chamaecyparis obtusa var. formosana—Rhododendron formosanum type, Fagus hayatae type, Symplocos arisanensis‐Illicium anisatum type on Quercus upper zone; Tsuga chinensis var. formosana and Pinus taiwanensis type on Tsuga‐Picea zone; Abies kawakamii type on Abies zone.
经TWINSPAN分析及参考DCA结果,可将植物社会区分为6个植群带10个植群型,分别为榕楠林带的茄冬‐大叶楠型;楠槠林带的黄杞‐长尾尖叶槠型;栎林带下层的台湾杜鹃型、大叶石栎‐猪脚楠型;栎林带上层的台湾扁柏‐台湾杜鹃型、台湾水青冈型及阿里山灰木‐白花八角型;铁杉‐云杉林带的台湾铁杉型、台湾二叶松型;冷杉林带的台湾冷杉型。

Larches of different ages have different net photosynthetic rate: the photosynthetic capacity of the young ones are bigger than that of the old ones; the stand density do not affect the net photosynthetic rate obviously; as far as the different stand classes are concerned, the diurnal changes of net photosynthetic rate is closely related to the photosynthetic active radiation. For the different layers of the crowns, there are greater ecological factors (illumination intensity, temperature, humidity etc.) on the upper layers than on the lower layers: the CO2 concentration of the lower layers is greater than that of the upper layers, which is indeed an exception; the net photosynthetic rate on the upper layers of the crown is generally greater than that of the lower layers. It showed that the CO2 concentration is not a main factor in the natural changing range of the CO2 concentration. Different directions of the crown have different photosynthetic active radiation, which is generally like exposed to the sun﹥North﹥in the shade of crown. However, the changes of net photosynthetic rate are not quite the same, which is North﹥exposed to the sun﹥in the shade of crown.
不同年龄的兴安落叶松净光合速率不同,年龄小的个体光合能力高于年龄大的个体;群团密度与净光合速率没有显著的相关关系;而对不同分级木,净光合速率日进程变化规律与光合有效辐射有着密切的联系;林内树冠不同层次各生态因子有上层大于下层的趋势,而CO2浓度在下层的含量高于上层,净光合速率上层普遍大于下层,说明在林内自然CO2浓度变幅内,CO2浓度不是主要因子;兴安落叶松树冠不同方向的光合有效辐射不同,一般向阳﹥北向﹥背阴,而净光合速率变化有北向﹥向阳﹥背阴的趋势。
