流域土地退化研究综述

Progress in the Research on Basin Land Degradation

土地作为流域重要的组成资源,对调节流域生态平衡及社会经济发展至关重要.从流域土地退化的定义界定、原理、退化类型及其现状、监测手段及方法和退化风险评价指标体系等方面对国内外学者的研究进行了评述.为了更深入研究流域土地退化及相关监测的应用,建议加强流域土地退化监测系统的开发、土地退化防治与生态系统的重建,完善土地退化(风险)评价体系指标的构建、土地退化时空特征分析等研究.

As an important component of land resources, basin can regulate ecological balance and socio-economic development. From the aspects of basin land degradation mechanisms, types and status quo, monitoring methods and evaluation index system of land degradation and other research scholars were reviewed. In order to further study the basin land degradation and related monitoring applications,it is recommended to strengthen the monitoring of basin land degradation system development,build evaluation system indicators of land degradation, land degradation prevention and rebuilding ecosystems, land degradation temporal characteristics of other research.
