摘　　要：高强度土地转换及持续的土地利用活动对土壤的发育方向具有双重作用,显著影响土壤多样性。本研究首先概述了土地利用方式对母质来源、局地小气候、微地形、植被类型、管理措施和成土时间的作用;其次,在系统归纳土壤物理、化学和生物学性质对土地利用变化响应规律的基础上,总结了土地变更对土壤发生学属性、形态学特征和诊断特性的影响,进一步综述了土地利用方式转变后,不同等级土壤类型演变规律。最后,指出应加强研究多样化土地利用活动对成土过程、土壤属性的影响,重视土壤发生学性质对土地转换与渐变的动态响应规律,并应用新技术准确高效辨识土地利用方式变更引起的土壤类型变化。High-intensity land conversion and persistent land use activities exert dual effects on soil development,which can significantly influence pedodiversity.We first reviewed the influences of various types of land use on the source of parent materials,microclimate,microrelief,vegetation cover,management practices and soil age.Then based on our systematical analyses of the effects of land use change on soil physical,chemical,and biological properties,we summarized the effects of land conversions on soil genetic,morphological,and diagnostic characteristics.We also comprehensively evaluated soil type evolution trends in different classification categories in response to land conversions.Finally,we proposed three research priorities:(1)an overall understanding of the effect of diverse land use activities on the soil properties and formation processes;(2)deep exploration of dynamic soil genetic responses to land cover conversions and modifications;(3)and development of new technologies for exact and high-efficiency identification of soil type change with land use change.
