摘　　要：地表基质是基于地球系统科学理论,为服务支撑自然资源综合管理而提出的概念。从地表基质的概念出发,从物质属性、空间特征、生态功能3个方面剖析地表基质的本质属性,并详细阐释其内涵特征。通过分析该领域内的研究热点并结合实践经验,总结了现行分类方案中存在的主要问题。通过对相关问题的分析,在遵循“科学性、从先性、统一性、通俗性”原则的基础上,制定了新的地表基质三级分类方案,新方案共划分5个一级类、19个二级类和若干个三级类。基于该方案,选取内蒙古东部的雅鲁河流域为研究区,提出了“建立同一深度范围内固定深度的地表基质垂向构型”的编图思路,利用野外测量与室内测试数据编制了雅鲁河流域地表基质图。研究可有效促进地表基质调查与应用服务的紧密融合,对建立地表基质调查技术方法体系具有参考价值。The ground substrate concept was proposed based on earth system science theories,with the purpose of serving and supporting the integrated management of natural resources.The essential properties of ground substrate were deeply analyzed from three aspects,that is material properties,spatial characteristics and ecological function,based on the concept of ground substrate,and its connotation characteristics were elaborated.The main issues in the current classification scheme were listed on the basis of researching the hot spots in the field and combined with practical experience.Based on the analysis of related issues and the principle of“scientific,prioritization,uniformity and popularity”,the authors formulated new three-level classification scheme.The new classification includes 5 first-level,19 second-level and several third-level categories.Yalu River Basin in the eastern Inner Mongolia was selected as the study area based on this new scheme and new mapping approach was proposed as construction of vertical configuration at a constant depth in ground substrate layer.And the ground substrate map was compiled by fieldwork measurement and laboratory data.This study could effectively promote the close integration of ground substrate survey and application services,and also has significant reference value for technical methodology establishment.
