封山育林是促进喀斯特地区植被恢复的重要措施。通过设置4个固定样方,对广西南亚热带喀斯特地区植被群落结构特征进行连续监测,对植被结构随治理时间变化的规律进行了研究。结果表明：植被的物种多样性随着治理年限的增加而得到改善和提高。受人为干扰的影响,4个样方不同植被层次的各项多样性指数变化趋势不一致,人为干扰程度强,物种多样性就降低。

Closed forest is an important measure to promote the vegetation recovery in Karst area. By set-ting four fixed quadrats, the structural features of the vegetation community in the south subtropical Karst area in Guangxi were continuously monitored. The change law of vegetation structure with time was stud-ied. The results showed that species diversity of the vegetation was improved and enhanced with increas-ing age of governance. Affected by human disturbance, diversity index were inconsistent trend in different layers of 4 plots. Species diversity was reduced as the human disturbance enhanced.
