摘要：植被是生态系统中物质循环与能量流动的中枢。植被退化是在不利自然因素及人类不合理的活动影响下生态系统逆行演替的一种过程与结果，是土地荒漠化的主要诱因。本文在回忆国内外植被退化研究进展的根底上，总结了植被退化的研究历程和退化程度的定量监测评价方法，探讨了植被退化研究方法尚存在的问题，展望了能够全面系统、快速简单监测评价植被退化程度的新方法的引入。

Abstract: Vegetation is the hub of material circulation and energy flow in ecosystem. Degradation of vegetation is a retrograde succession process and result of ecosystem under the influence of adverse natural factors and unreasonable human activities, the primary cause of desertification. This paper, based on the review of research progress in degradation of vegetation at home and abroad, summarized the research history of vegetation degradation and quantitative monitoring and evaluation methods of degradation degree, explored and discussed remaining problems of vegetation degradation, and look the introduction of new methods which is capable of comprehensive, systematic, quick and simple mon
