为了研究封山育林对石漠化植被恢复效果，为岩溶地区石漠化的治理提供理论依据，采用样地调查的方法。对封山育林区的植被状况、土壤有机质含量等方面进行了研究。研究结果表明，封山育林前植被总覆盖度为44％，植被种类仅为121种，且生长状况较差；封山育林后植被总覆盖度为85％，植被种类为194种，生长状况良好。封山育林后0～20cm土层有机质含量比封山育前提高4．43g/kg，封山育林后20-40cm土层有机质含量比封山育林前提高3．22g/kg，全N，全P，全K等在不同程度上均有所增加。

In order to study the effect of closing hillsides to facilitate afforestation on vegetation recovery in rockydesertification areas, the research was made through sample survey on the vegetation situation of afforestation areas and organic matter content of soil. The results showed that the overall vegetation coverage was 44% and the vegetation type was only 121 with a poor growth condition before closing hillsides to facilitate afforestation; after afforestation, the overall vegetation coverage was 85% and the vegetation type became 194 with a good growth condition. The organic matter content of soil in 0 - 20 cm after afforestation increased by 4.43 g/kg compared with that before afforestation. The organic matter content of soil in 20 - 40 cm after afforestation rose by 3.22 g/kg compared with that before afforestation. And total N, P and K went up at different levels.
