| 摘 要： | 在对马关都龙镇锌铟矿山废弃地所设置的10种植被恢复配置模式试验所形成的群落进行植被调查和土壤养分测定的基础上，分析了山黄麻在各群落类型中的生长差异、分布与生态因子的相关性。结果表明，在该废弃地上，山黄麻迁入定居除受种子散布及植被恢复过程中草本层盖度影响外，能适应不同植物群落、不同土壤养分环境，其树高年均生长量为1.8 m，胸径的年均生长量达1.6 cm，树高和胸径的生长速度分级达速生水平，表现出对马关锌铟矿山废弃地较强的生态适应能力。山黄麻可作为马关锌铟矿山废弃地植被恢复初期的先锋树种加以利用。

| Abstract: | The vegetation and soil nutrition of the communities formed by 10 revegetation disposition models in cop-per-zinc mine wasteland were investigated in Dulong township of Maguan county , Yunnan .The growth difference , relationship between distribution and ecological factors of Trema tomentosa in different communities were analyzed . The results showed that in this wasteland T.tomentosa can adapt to different plant communities and soil nutrition , and was influenced by seed distribution and herbage coverage .Annual growth amount of height and DBH was 1.8 m and 1.6 cm, and its growth rate reached to fast-growing level, which showed a strong ecological adaptabili-ty.Therefore T.tomentosa can be used as the pioneer plant at the early stage of revegetation in copper-zinc mine wasteland . |
