| 摘 要： | 通过对小兴安岭地区曾遭受严重破坏并实施封山育林后的针阔混交林、杨桦林和蒙古栎林的结构特征进行分析研究表明 :封山育林是促进森林植被恢复的有效措施 ,植被恢复比较迅速 ,植被高度、盖度及物种数均发生明显变化 ,尤其是垂直结构变化明显。对封山育林后的土壤理化性质的分析 ,表明土壤含水量和腐殖质含量增幅明显

| Abstract: | Through analyzed the character structure of mixed coniferous and broadleaf stands, poplar-birch forest and Quercus mongolica forest after closed forest that badly destroyed in Xiaoxing'an Mountain,it showed that closed forest is an effective method to promote the forest vegetation recovery, after closed forest, the vegetation recovery very fast, the height, cover rate of vegetation and number of genus also change very much, especially the vertical structure have evident changed. From the analysis of physical and chemical characters of the soil, it showed that after closed forest the percentage of moisture and humus in soil increased greatly. |
