【Abstract】 This paper analyzed the cause, characteristics and types of degraded ecosystem. Based on the enlarged terminology of soil functions, the authors introduced the definition and types of soil quality, explained the effects of erosion to soil physical, chemical and biological qualities. The selection and assessment of soil quality index for restrong erosive degraced ecosystem were given.Accordingly, introduced the management measures of degraded soil quality. We should apply the quantifiable soil quality index to disern the range and degree of degraded soil in order to give some methods for it’s restoration.更多还原
