摘要
地球关键带分类有助于认知关键带的空间布局,了解其发生和演化的区域差异性,并可以作为观测和调查关键带的基础.为了延续大尺度地球关键带分类,在分析关键带组成要素的基础上,采用多层级划分法构建了一套小尺度关键带分类的框架,并在GIS中以图层叠置法对河南省西峡县做了实证研究.建立了一套涵盖分类原则、分类指标的多层级地球关键带分类框架,并将西峡县地球关键带划分为 28 个一级类型单元,246 个二级类型单元和 722 个三级类型单元.这种划分可以提高对地球系统科学的整体认知,对小尺度地球关键带的科学研究和自然资源综合管理也具有一定的参考意义.
Abstract
The classification of Earth Critical Zone is helpful to cognize the spatial distribution and understand the regional differences in the occurrence and evolution of Critical Zone.Besides,it is the basis for the observation and investigation of Critical Zone.To further study the existing large-scale Critical Zone classification,this study constructed a set of small-scale Critical Zone classification frameworks using a multi-level classification method.It made an empirical study of Xixia County in Henan Province by using the map overlay method in GIS.The research results showed a group of multi-level classification frameworks covering classification principles and indexes in the mountainous area,and the Critical Zone of Xixia County was divided into 28 first-level types,246 second-level types,and 722 third-level types.This classification can improve the overall understanding of earth system science.It also has specific reference significance for scientific research and the comprehensive management of natural resources in the critical zones of the earth at different scales.
