| 中文摘要 | 以甘肃省林业科学技术推广总站徐家山后山试验基地及皋兰山的部分山地为例，对人工植被、封育区、对照区群落的植被盖度、不同物种的重要值、群落的多样性进行了调查分析。结果表明，在以兰州市北山为代表的干旱地区进行无灌溉造林，只要树种选择得当，造林技术措施正确，生态环境可以逐渐得到改善；另外，封育也是这一地区植被恢复的有效途径。人工植被物种的重要值的大小排序是：柠条〉红柳〉侧柏〉沙冬青〉白刺〉野枸杞〉山杏〉山桃。红砂、合头草无论在任何情况下都能以优势种出现，是能够较强适应当地环境的植物。人工植被的物种多样性指数、群落的均匀度指数和物种的丰富度指数与封育区比较接近，与对照区差异较大。通过相似性比较，人工造林地、封育区与对照区在相似性方面均有较大差异，随着植物种数量和种类的不断增加，三者会表现出更大的差异性。 |
| 英文摘要 | By taking parts of Mt. Gaolan and the Xujiashan Experimental substation, General Extension Station of Forestry Science and Technology of Gansu Province as examples, the coverage of vegetation communities, important value of different communities, and species diversity in artificial vegetation region, enclosed region, and contrast region were investigated. The result indicates that as long as the tree varieties are properly chosen and technological measures for afforestation are suitable to local conditions, the ecological environment in the area similar to that in the north mountain of Lanzhou City can be gradually improved. In addition, the enclosure measure is proved to be an effective way for vegetation restoration in the region. The artificial vegetation species, in terms of their important values, rank in the descendant order of Caragana microphylla , Tamarix ramosissima , Platycladus orientalis , Ammopiptanthus mongolicus , Nitraria sibirica , Lycium chinense, Prunus aymeniaca, and Prunus daridiana. Under any circumstance, Reaumuria soongorica and Sympegma regelii Bge are dominant species, showing a strong adaptation to local environment. Diversified index, evenness index, and richness index of artificial vegetation are close to those in enclosed forest region and differ greatly from those in contrast region. Using comparability comparison methods, we can conclude that artificial vegetation region, enclosure region and contrast region have greater differences in the comparability analysis. With the constant increase of species quantity and types in forest, the three areas themself will demonstrate greater differences. |
