土壤多样性研究进展

Research progress on theory and practice of pedodiversity

土壤多样性研究是土壤学、土壤地理学与生态学相结合的一个新领域,它吸收了生物多样性的研究方法。本文在总结当前国内外相关研究的基础上,阐述了土壤多样性的概念,并对土壤多样性的相关研究方法,如生物多样性测度方法、多度分布模型方法及种—面积关系法、嵌套子集方法和分形理论方法等的应用实践进行了归纳。最后介绍了我国当前土壤多样性的研究现状,指出土地利用变化的研究为土壤多样性驱动因子的研究开辟新的路径。

Pedodiversity research is a new field from a combination of pedology,pedogeography and ecology.It adopts methodology of biodiversity.Based on the related domestic and international research progress,this paper reviewed the concept of pedodiversity and summarized some methods used for pedodiversity research such as biodiversity measure,abundance distribution model,species-area relationship,the nested subset method and the fractal theory.Finally the paper also introduced current situation of pedodiversity researches in China and pointed out that land use change analysis would provide a new approach for studies on driving factors of pedodiversity.
