| 摘 要： | 根据四川省冕宁县城厢镇刹叶马村滑坡迹地自然恢复早期植被的野外调查资料与数据统计分析，结果如下：（1）在研究区域内共记录到维管植物58科137属176种，其中蕨类植物6科7属7种，裸子植物1科1属1种，被子植物168种，隶属于51科129属．（2）构成研究区域植被自然恢复早期的种子植物有52科，分属7种地理成分，以世界广布的科最多，热带性质的科与温带性质的科比例接近．同时130属种子植物可划分为12种分布区类型，温带性质的属多于热带性质的属，世界分布属仍有较大比例．（3）群落分类的结果得到6种群落类型，代表了自然恢复过程中不同小环境条件下形成的先锋群落，各个群落中的优势物种则代表了自然建群中的先锋物种．DCA排序的结果反映了多种环境因素对植被自然恢复的影响，提出加强对山体滑坡地段植被自然恢复进一步研究的必要性．

| Abstract: | Landslides and debris flows are main natural disasters in the mountainous area and ecological restoration is an effective measure for bare slope after landslide breaks out.Studying on vegetation by natural recovery in this region can help to find scientific and rational way to resolve the problem of vegetation restoration.In this study,we have investigated the naturally restored vegetation in a landslide area and the results are as follows:(1) There are 176 species of vascular plants belonging to 137 genera... |
