土壤多样性理论在欧美的实践及在我国土壤景观研究中的应用前景

介绍了土壤多样性理论的基本概念与研究方法以及在西班牙、美国等欧美国家的研究实践 ,包括在欧盟 CORINE数据库和美国 STATSGO数据库支持下进行的多样性主要指数 (多样性指数、均匀度指数和多度指数等 )的算法、主要模型 (多度分布模型、幂律模型等 )的分析、GIS和地统计学方法的应用等。通过这些研究实践 ,可以看出土壤多样性理论在研究土壤的空间可变性、土壤景观格局的相互关系 ,土地利用与城市化过程对土壤多样性的影响等方面确有独到之处 ,为解决当前我国土壤学面临的环境资源可持续发展、环境监控、基因保护、城市化过程等热点问题提供了一个崭新的研究思路 ,展现出良好的应用前景

What to do in China after a review of researches practices on pedodiversity in Europe and America

Species diversity indices, Abundance distribution models and diversity-area relationships are tools of biological diversity analysis that have been used by ecologists for decades while little attention has been paid to analyses of pedodiversity. Only recently, these techniques were considered in a more general setting, and have been applied to explore notions such as pedodiversity (as an example of geodiversity in a broad sense, including also geomorphic diversity), in order to detect the differences and si...
