2008-2017年天童不同演替阶段典型常绿阔叶林植物物种组成和生物量数据集

A dataset of species composition and biomass in different successional stages of Tiantong typical evergreen broad-leaved forests(2008-2017)

森林演替规律是森林植被的基本属性之一,是深入认识森林群落、正确管理和合理利用森林的基础。典型常绿阔叶林(typical evergreen broad-leaved forest)是中国东部中亚热带地区的地带性植被。由于人为和自然干扰,现存植被多处于不同的次生演替阶段。群落物种组成是反映森林生态系统生物要素特征的重要指标,是开展常绿阔叶林结构、功能和动态研究的基础。按照国家生态系统监测网络监测规范,浙江天童森林生态系统国家野外观测研究站在2008-2017年对典型常绿阔叶林演替系列3个不同演替阶段固定样地,包括演替前期的常绿灌丛样地、演替中后期的木荷林样地和演替顶级的栲树林样地,进行了3次群落调查,记录所有木本植物个体的物种名、胸径/基径、高度等信息。本数据集包含了不同演替阶段森林群落植物物种组成数据,包括种名、多度、平均胸径/基径和生物量等。本数据集可为亚热带典型常绿阔叶林演替规律、群落构建机制、植被恢复等方面研究和应用提供数据支撑。

As a basic properties of forest vegetation, the forest succession law is the basis for understanding the correct management and rational utilization of forests. Typical evergreen broad-leaved forests are a type of zonal vegetation in the subtropical area of Eastern China. The existing vegetation is mostly in different secondary succession stages due to human and natural disturbance. The composition of plant species is an important indicator of the forest ecosystem and the basis for the study on structure, function and dynamics of evergreen broad-leaved forests. According to CNERN monitoring standards, Zhejiang Tiantong National Forest Ecosystem Observation and Research Station carried out three field surveys on three succession plots and established a dataset of species composition from 2008 to 2017. The succession plots are evergreen shrub plot, Schima Superba forest plot and Castanopsis fargesii forest plot, respectively, covering the information of species name, abundance, mean diameter and biomass of woody plants on the plots. The database provides critical data for the study on and application of succession, community assembly and forest restoration in subtropical typical evergreen broad-leaved forests.
