土壤多样性:土壤地理学研究的契机

Pedodiversity: An Opportunity for Soil Geographic Studies

介绍了土壤多样性研究的起源、概念及学科意义,在此基础上系统论述了土壤多样性在国内外的主要研究进展和取得的主要成果,并对未来的应用前景进行了展望。首先,生物多样性的保护是以土壤多样性为基础的,保护土壤多样性意义重大,而事实证明广泛应用于生物学中的计量方法同样适用于土壤地理学和土壤资源有关研究中;其次,有关国家已经在土壤多样性的测度方法及其在土壤资源空间表达中作了很多尝试,诸多案例为土壤地理学研究提供了新的角度;最后,新近研究及发展方向主要集中在土壤多样性与土地利用多样性、土地利用类型(耕地、水体、植被等)多样性的关联分析中,已经取得显著进展。这一研究领域日趋活跃,将在土壤地理学及土壤资源相关研究中扮演重要角色并呈现良好的发展前景。

The origin, concept and significance of pedodiversity are introduced before the related research progress and publications home and abroad are briefly discussed. Firstly, biodiversity is based on pedodiversity which is very important to be conserved by using all the methods widely applied in traditional biological studies. Secondly, a new studying opportunity should be found from all the publications in which many efforts have been made to express the spatial distribution patterns of soils resources. Finally, the mostly recent research reports focus on correlative analysis of pedodiversity and land use type diversity inclusive of arable land, water and vegetation resulting in some new findings already. Pedodiversity analysis has been developed nicely and will play a more active role in the future soil geographical and soil resource studies.
