生物地理模型研究进展及在干旱半干旱区的应用

Advances in Researches of Biogeographic Model and Its Application in the Arid and Semi-Arid Regions,China

生物地理模型是实现生态保护计划的重要工具。从生物地理模型研究的背景出发,论述了它的发展是科学和实践的需求,分析了基于生态位理论的生物地理模型发展所面临的挑战,特别是数据的获取和关键变量的选择,展望了生物地理模型的发展前景,并对其在干旱半干旱区的应用进行了综述,旨在理解生物地理模型在陆面过程研究和生态恢复中的重要性,以期推动生物地理过程与之相关过程的耦合模拟研究。

Biogeographic model has been used as an important tool for conservation planning. We discuss the background of biogeographic model development and find it has mostly contributed to both fundamental and applied research in biogeography and ecology. And its development is in need of theory and application. The challenges are discussed in this paper, especially when the problems happened during the model application such as false absences and false presences in species data, and key environmental variables selection. We prospect the development of biogeographic model in the future： it needs to couple climatic model and biogeochemical model. We selectively re- view the literature of biogeographic studies in arid and semi-arid regions of China. It is very essential to understand the significance of biogeographic model for depicting biogeographic processes and conservation planning application. Our objective is to promote the modeling researches courses about biogeographic processes coupling with other rela- tive processes.
