摘　　要：鉴于全球植被 /生物群区在现状气候条件下已经被很好地模拟并在未来气候变化情景下得到很好的预测 ,人们有必要和急需模拟大尺度 (区域、洲际至全球 )植物多样性的分布格局。陆地生物圈模型的发展 (从生物地理模型和生物地球化学模型到动态和耦合的植被模型 ) ,气候_生物多样性相互关系和生产力_生物多样性相互关系研究成果的增多 ,以及基于现有生物多样性调查的全球生物多样性理论和经验制图的进步 ,加大了模拟大尺度植物多样性格局的可能性。本文的目的是 :综述当前气候_生物多样性相互关系和生产力_生物多样性相互关系的主要研究成果以及大尺度生物多样性格局制图的发展 ,简要论述陆地生物圈模型的发展及现状 ,以此寻找利用植被模型并基于气候_生物多样性_生产力相互关系来模拟大尺度植物多样性的可能性。综合分析发现 ,利用基于过程的平衡态陆地生物圈模型和动态植被模型 (驱动因子为气候数据和植物种的生态生理限制 ,如叶面积指数和净第一性生产力 ) ,在模拟植被分布的同时可模拟大尺度的植物多样性 (此处定义为一定面积上植物种的数量 )格局 ,全球植物多样性的现状分布图可作为比较模拟的植物多样性和潜在植物多样性分布的有效工具。然而 ,从文献分析中也可以看出 ,对全球植物多样性实际分布认识?As vegetation/biomes in the world has been well simulated in current climate and predicted in future climatic scenarios, it is urgently needed and necessary to simulate the large-scale (regional, continental to global) distribution of plant diversity. The development of terrestrial biosphere models from the biogeographical and biogeochemical models to dynamic and coupled vegetation models, the increasing achievements of relationships between climate and biodiversity and between productivity and biodiversity, as well as the theoretical and empirical products of mapping global biodiversity based on the existing field biodiversity investigation, accelerated the possibility of modeling large scale patterns of plant diversity. The aim of this paper is 1) to review the current situation of climate-biodiversity relationships, production-biodiversity relationships and the mapping of biodiversity patterns at a large scale, 2) to review the development of terrestrial biosphere models briefly, and then 3) to look for the possibility of modeling large-scale plant diversity using vegetation models and based on the climate-biodiversity-production relationships. Using the process-based equilibrium terrestrial biosphere models, the dynamic vegetation models driven by climate data and ecophysiological constraints of plant species such as leaf area index and net primary productivity, the large-scale pattern of plant diversity (the species count in a given area) can be simulated in the same time when modeling the vegetation distribution. The global map of plant distribution will become a good tool for comparing the simulated plant diversity with potential ones. However, limitations of knowledge about the actual distribution of global plant diversity, relationships among climatic constraints, productivity and biodiversity, as well as natural and human disturbances on biodiversity will restrict the more accurate simulation of plant diversity at present. How to simulate the plant diversity more accurately and more mechanically is a fu
