2001年亚热带典型常绿落叶阔叶混交林物种组成数据集

A dataset of species composition in a typical subtropical mixed evergreen and deciduous broad-leaved forest(2001)

常绿落叶阔叶混交林是常绿阔叶林和落叶阔叶林之间的自然过渡类型,是对气候波动较为敏感的植被类型之一。通过调查野外固定样地,本数据集收集了2001年我国常绿落叶阔叶混交林固定监测样地胸径4 cm以上树种的组成信息,主要包括35科58属81种乔木物种的学名、平均胸径、多度、重要值、叶习性、耐阴性、演替状态等信息。用户可以按照物种名称、叶习性和演替特征进行数据检索。典型常绿落叶阔叶混交林样方数据库的建立与共享,为理解未来全球变化条件下该类型森林的动态特征及其对气候变化的响应提供了数据支撑,有助于提升常绿落叶阔叶混交林的科学研究,对推动我国植被生态学的长期研究具有重要意义。

The mixed evergreen and deciduous broad-leaved forest is a natural transitional vegetation type between evergreen broad-leaved and deciduous broad-leaved forests,which is sensitive to climate change.According to field investigation of fixed sampling plots,the species composition of woody plants with diameter at breast height(DBH)of 4 cm or more in the mixed evergreen and deciduous broad-leaved forest of China in 2001 were recorded.The data comprised the scientific name of species,average DBH,abundance,importance value,leaf habit,shade tolerance,succession status,containing 81 species in 58 genera,from 35 families.Users can search the data according to the species name,leaf habit,or succession status.The setup and data sharing of this typical subtropical mixed evergreen and deciduous broad-leaved forest database will provide important evidence for a better understanding of the dynamic characteristics of this type of forest and its response to climate change.It will assist with the enhancement of the scientific research of mixed evergreen and deciduous broad-leaved forests and is of significance to the study of long-term vegetation ecology in China.
