%X 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 future challenge for ecologists. The modeling of Chinese plant diversity at the country level has not been reported. The challenge to Chinese ecologists is to compile the available field records of plant counts as accurately as possible and then to map the country-scale plant diversity using the Geographical Information System and predict the potential distribution of plant diversity using vegetation models.
