摘要
土地分类是土地评价、规划和管理的基础 ,对林业资源可持续利用具有重要的意义 .生态土地分类是目前土地分类的主要方向和趋势 ,国际上早已开展此项研究 .随着景观生态学和 3S技术的发展 ,生态分类系统的研制已成为生态土地分类的重点 .本文对生态土地分类的定义、特点、发展历史、生态分类系统理论 ,以及国际生态分类系统的发展趋势进行了系统的综述 ,并指出以资源 (森林、土地、水域等 )多目标管理为基础 ,定量与定性相结合的多因子多层次综合是未来生态土地研究发展的总趋势 ,有必要在我国大力开展相关研究 .
Land classification is the base of land evaluation, land planning and land management, and plays an important role in the sustainable development of forestry resource. Ecological land classification (ELC) is the main approuch and direction of land classification. Along with the development of landscape ecology and 3S techniques, developing of ecological classification system (ECS) becomes the keystone of ELC. The definition, history, basic characteristics of ELC, the theory of ECS and its' prospects were systematically reviewed in this paper. The prospects were also described for the development of ECS methodology and the application of ELC. The general direction of ecological land research, which was a multi factors and multi levels syntheses based on the multi objects administration of resource (forest, land and waters), was the combination of quantificational and qualitative research. It is necessary to carry out relevant researches in China.
