山地植物群落数量分类和排序研究进展

在区域至全球尺度上,水热条件是决定植物种、生活型或植被类型分布的主导因素，而在景观及更小的尺度上,区域环境因子则主导着植被的分布格局。数量分类和排序是研究群落生态关系的重要数量方法,它为客观、准确地揭示植被、植物群落及植被与环境之间的生态关系提供了合理、有效的途径。笔者从群落分布格局和物种多样性格局的角度出发,综述了我国山地植物群落数量分类和排序的相关研究,阐述了采用数量分类和排序方法研究山地植被与环境因子关系的必要性,并探讨了我国山地植物群落数量分类和排序研究的发展趋势以及亟待解决的一些问题。

Research progress on quantitative classification and ordination of mountain plant communities

From a small region to global scale,water and heat are the leading factors of determining the distribution of plant species,life-form and vegetation types.But in the landscape or even smaller scales,regional environmental factors decide the structure of plant community.Quantitative classification and ordination are the important methods for studying community ecological relationships,providing a reasonable and effective way of revealing the relationship among vegetation,plant community and environment objectively and exactly.From the perspective of the pattern of community distribution and species diversity,this paper summarized the research progress on quantitative classification and ordination of mountain plant communities in china,analyzed the necessity of using quantitative classification and ordination methods to study the relationship between vegetation and environmental factors,as well as practically discussed developmental tendencies and some urgent problems in the future research of the fields in terms of the realities in China in order to play an important reference for the research of mountain ecology and the ecological relations of mountain vegetation communities.
