摘　　要：以贵州省喀斯特土石山区为例,通过总结前人的研究成果和中国科学院亚热带农业生态研究所喀斯特生态实验站的部分试验数据,从全局性、紧迫性、高效性、层次性、可持续性、创新性与多样性的角度提出了在贵州喀斯特土石山区的急坡地、陡坡地、缓陡坡地其水土保持生态经济型植被恢复模式分别采用3种典型模式,即:灌草模式,乔灌草模式与林果模式,以期促进该区域的生态、经济与社会的全面协调与可持续发展。This paper took the Karst mountainous earth-rock areas in Guizhou as example,by summarizing the achievement of previous studies and collecting information and experimental data from Experimental Station of Karst Ecology of Institute of Subtropical Agriculture,Chinese Academy of sience,this paper put forword three typical eco-economic vegetation restoration models of soil and water conservation in sharp-slope,steep-slope and moderate steep-slope of the Karst mountainous earth-rock areas in Guizhou from the view of overall situation,urgency,efficiency,hierarchy,sustainalilinty,innovation and diversity.These three models were shrub-grass mode,arbor-shrub-grass mode and forest-fruit mode,which are expected to promote an all-round,sustainable and harmonious development of ecology,economy and society in the studied area.
