摘要土壤多样性作为土壤地理学研究领域的前沿性内容,可定量化描述土壤的空间变异性和分布格局问题,日益受到国内外广泛关注。在简要回顾了土壤多样性在国外的产生和发展过程后,着重对该专题在中国近15年的发展历程进行了深入分析,并对中国土壤多样性研究的发展特点和趋势进行了分析与总结,根据研究时期、内容和目的的不同,认为中国土壤多样性研究可以划分为引起与探索时期以及拓展应用时期,除以丰富度指数、仙农熵和均匀度指数为主的经典多样性计量方法外,新提出的土壤空间分布多样性为传统方法提供了重要的数据补充,该专题在土壤地理学和其他相关学科中仍具有广阔的应用空间和发展前景。 As one of the most recently developed research field in soil geography, pedodiversity theory with its methodology is widely spread and getting more attention at home and abroad due to its application in quantitatively describing the spatial variability and distribution pattern of regional soil resources. In this paper, after a brief re- view of the emergence and development process of pedodiversity in foreign countries, an intensive research has been made in analyzing the development process in the past 15 years of pedodiversity studies in China before summarizing the development characteristics and trends of Chinese pedodiversity research. In recent years, pedodiversity studies in China have combined pedodiversity with many different elements such as land use, nested analysis, urbanization process and water resources, making this research field more open and practical. It is believed that the Chinese pedodiversity research could be divided into a causation and exploration period and an extended application period due to their differences on research period, content and purpose which the first period is from 2001 to 2005 and second from 2005 to now. And besides the classic diversity measurement methods, such as richness index, Shan- non entropy and Pielou index, the new proposed index of soil spatial distribution diversity could provide an important data supplement for the classic methodology. Therefore, the pedodiversity topic still has strong and broad appli- cation space and development prospects in the soil geography and other related subjects.
