海拔高度与生态群落多样性和组成的关系研究可以追溯到地理学的起源。现代对这些海拔高度的兴趣的复苏可能会为发展一个更普遍的物种多样性理论提供重要的见解。为了更全面地了解多样性中的地理分布，山地植物地理学研究方案应包括对表观模式进行严格的统计检验，比较不同区域和物种分类或生态群体之间的模式，并在进行植物地理学调查的同时分析环境变量中的分布。这一研究方案的概念框架应基于这样一种假设，即物种多样性的海拔梯度是生态和进化过程相结合的结果，而不是假定的一种压倒一切的力量的独立影响。鉴于山地生态系统是生物多样性的热点，一个扩大的综合方案，在山区的地理调查应提供宝贵的见解，保护生物学家。
Studies of elevation dines in diversity and composition of ecological communities date back to the origins of biogeography. A modern resurgence of interests in these elevational dines is likely to contribute important insights for developing a more general theory of species diversity. In order to gain a more comprehensive understanding of geographical dines in diversity, the research programme for montane biogeography should include statistically rigorous tests of apparent patterns, comparisons of patterns among regions and taxonomic or ecological groups of species, and analyses of dines in environmental variables concurrent with biogeographical surveys. The conceptual framework for this research programme should be based on the assumption that elevational gradients in species diversity result from a combination of ecological and evolutionary processes, rather than the presumed independent effects of one overriding force. Given that montane ecosystems are hot spots of biological diversity, an expanded and integrated programme for biogeographic surveys in montane regions should provide valuable insights for conservation biologists.
