| 摘 要： | 针对野生甘草如何合理采挖问题,选取采挖甘草后的甘草群落为研究对象,进行不同封育年限的甘草群落结构及甘草产量、质量的比较研究,结果表明:1)甘草群落随着封育年限的增加物种丰富度增加,物种多样性减少,甘草的重要值下降;2)随着封育年限的增加甘草群落主要物种空间分布格局发生变化,逐渐由随机分布或均匀分布转向聚集分布;3)甘草产量在封育前期增加较快,随后甘草产量变化不大。4)甘草质量在封育3年时最高,随后下降。5)从甘草产量和质量方面考虑,野生甘草的采挖应该在采挖3年后进行。

| Abstract: | To discuss the reasonable excavation of wild G.uralensis,G.uralensis comunity exclosed after the root of G.uralensis was excavated.The experiment was conducted to study the change of community structure,spatial distribution pattern of the main populations,yield and quality of G.uralensis in a community that was fenced in different years.The main results are as follows: 1) With the years of exclosure increasing,the richness index becomes larger and the diversity index tends to reduce and the important values... |
