中国暖温带针叶林植被分布研究

Research on Vegetation Distribution of Coniferous Forest in Warm Temperate Zone of China

根据中国暖温带针叶林的群系分布资料和气象站资料,在张新时对Holdridge分类系统修正的基础上,将中国暖温带划分为年均生物学温度(ABT, Annual biotemperature) 10℃~14℃,对中国针叶林178个群系进行计算。使用邬建国生态渗透模型60%占比对针叶林群系的图斑进行温度带划分,并计算群系暖温带图斑占比,研究针叶林群系在暖温带的分布格局。结果显示:中国暖温带针叶林群系组成丰富,共包含了47个群系,4种植被型。本文研究结果将为后续暖温带针叶林群系物种多样性的研究奠定基础。

According to the distribution data of coniferous forests in the warm temperate zone of China and the data of meteorological stations, and on the basis of Zhang Xinshi’s revision of the Holdridge classification system, the warm temperate zone of China is divided into annual biotemperature (ABT, Annuual biotemperature) 10˚C~14˚C. Calculations were performed on 178 groups of Chinese coniferous forests. Using the 60% proportion of Wu Jianguo’s ecological infiltration model, the temperature zones of the coniferous forest community were divided into temperature zones, and the proportion of the clusters in the warm temperate zone was calculated to study the distribution pattern of the coniferous forest community in the warm temperate zone. The results showed that the coniferous forests in the warm temperate zone of China were rich in composition, including 47 groups and 4 vegetation types. The results of this study will lay a foundation for subsequent studies on species diversity of warm temperate coniferous forests.
