摘要:

生态土地分类是随着景观生态学的进展与土地调查工作的开展而发展到世界规模的。生态土地分类的基本原理是,把土地视为一个景观,而景观无论在其各种属性之间,也无论在其各种要素之间,是相互作用的。生态土地分类的基本特点是对地域空间实体的区分,随着类等级由上向下,所划分的与一定比例尺相联系的土地单元在地域上越来越小。当前各国的生态土地分类的级别体系有向统一化和多级化的发展趋势。基于在河北省平山县卸甲河流域的个例研究,我们提出的分类系统包括三级,即土地系统、土地组合和土地类型,并分别对每一级给出相应的定义、评定标准和命名原则。在该流域的范围内,划分了8个土地系统,对于每一个系统分别划分了若干个土地组合和土地类型。

关键词: 生态土地分类, 土地系统, 土地组合, 土地类型

Abstract:

Whth the development of landscape ecology and the progress of land surveys, ecological land classification has been expanded to a world scale.The basic principle of ecological land classification is that land is regarded as a landscape interactive either among various land attributes or among various land elements.Ecological land classification is characterized by the divison of space entities in territory.As descending in hierarchy of classification, land unites in territory are divided into smaller and smaller areas.Now, in the world, the ecological land classification system tends to be multi-hierarchical and unified.Based on the case study of Xiejiahe drainage in Pingshan County, Hebei Province, a classification system is proposed to include three grades, namely, land system, land association and land type, simultaneously, to put forward the definition, division standards and nomenclature principles for each grade.In the studied region, 8 land systems have been classified.

Key words: Ecological land classification, Land system Land association, Land type,
