Abstract: According to the engineering need of grassland animal husbandry for national rocky desertification by comprehensive treatment, this paper summarized the forage shrub resources in karst rocky desertification area of Guizhou Province, and comprehensively evaluated its utilization value  using the subject theory like the ecology, botany, nutrition, etc. and pointed out that the shrubs represented by Magnolia multiflora，Amorpha fruticosa and Campylotropis macrocarpa were not only rich in nutritional value, but also had strong stress-resistance and comprehensive development and utilization value. This paper also analyzed the existing problems in developing and utilizing these forage shrubs in karst rocky desertification area, and provided counter-measures as vigorously developing non-conventional feed processing industry based on forage shrubs in these areas, which was an important guarantee for developing ecological animal husbandry, and also an effective way to improve the vegetation coverage during the comprehensive treatment process of karst rocky desertification.
