中国亚热带灌丛群落物种组成及分布的研究

Research on Species Composition and Distribution of Subtropical Shrub Communities in China

摘要: 本文利用2017年公开发布的1970~2000年即30年气候数据，以2001年科学出版社出版的中国植被图集(1:100万比例尺)为植被类型基础数据，参照以年均生物学温度作为热量指标的温度带划分，基于渗透理论(采用四邻规则)在生态学中的应用，对中国灌丛植被共95个群系进行计算归类。结果显示：中国亚热带地区灌丛物种组成丰富，共包含了45个群系，5种植被型，其分布主要集中在我国南部地区。本文研究结果将为后续亚热带灌丛群落物种多样性的研究奠定基础。

Abstract: This paper uses the 30-year climate data from 1970 to 2000, which was publicly released in 2017 and taking the China Vegetation Atlas (1:1 million scale) published by Science Press in 2001 as the basic data of vegetation types. Temperature zone division is based on annual average biological temperature as a heat indicator. Based on the application of infiltration theory (using the four-neighbor rule) in ecology, a total of 95 groups of shrub vegetation in China were calculated and classified. The results show that the shrub species composition in subtropical regions of China is rich. A total of 45 groups were included, involving 5 vegetation types, and their distribution was concentrated in the southern part of China. The results of this study will provide help for subsequent studies on the species diversity of subtropical shrub communities in my country.
