摘要

生态退化研究是当今生态学研究的热点问题之一。长期以来，生态退化的研究主要以土壤退化、植被退化、土地退化（实际上仍以土壤退化为核心）的单要素研究为主，而很少从生态系统的层次上加以研究，而且在研究方法上多以定性和半定量研究为主，因而不能很好地揭示生态退化的本质规律。目前，退化生态系统和脆弱生态环境的研究在国内外还刚刚起步，对于生态退化的概念与内涵尚无统一的认识，其研究内容也不明确，生态退化的研究方法和体系还不完善。基于此，该文对土壤退化、土地退化等生态退化的前期研究内容作了简要回顾，对生态退化有关的几个基本概念作了剖析，并对生态退化的层次和范围加以探讨。

Abstract

Ecological degradation research is one of the focused problems of today's ecology.A review of ecological degradation study and analysis on the concepts of degradation including soil degradation

land degradation

desertification and eco-degradation are given.The eco-degradation is divided into three levels:(1)single ecological factor;(2)natural ecosystem;(3) social-economic natural complex ecosystem (SENCE ).Finally

the study scope of eco-degradation is presented

which-includes:(1)theory and methodology of ecological of degradation;(2) mechanism and process of eco-degradation;(3)quantitative evaluation of eco-degradation;(4)prediction and systematic monitor of eco-degradation;(5)restorationand reconstruction of eco-degradation.
