摘要/Abstract

摘要： 在广西田阳县开展了封山育林对石灰岩山地植被恢复的影响研究。结果表明:封山3年后石灰岩山地植被恢复明显,2个试验地的物种多样性、重要值及植被覆盖率都发生了不同程度的改变。其中: A试验地的物种数增加了13种,增量达59.09%;重要值降多升少,植物在群落中的地位没有发生根本的改变;植被覆盖率提高了40%。B试验地的物种数增加4种,增量仅为19.05%;在重要值中,木本及藤本植物降多升少,它们在群落中的地位没有发生明显改变,而草本植物则升多降少,部分植物的地位已发生了根本改变;植被覆盖率达到了100%。

Abstract: Effects of hillside closing on vegetation restoration in different sites in limestone mountains were studied in Tianyang county, Guangxi Autonomous Region. The results showed that the effects of hillside closing on vegetation restoration were obvious in different sites after 3 years. There were 13 new plant species occurring in experimental site A and the increase ratio was 50.09%. The importance value of majority species decreased and minority species increased though their significance had not changed obviously in community. Total vegetation coverage increased 40% obviously. There were only 4 new plant species occurring in experimental B which was better site and the increase ratio was only 19.05%. Although importance value of most woody and liana species decreased, their significance had not changed obviously in community. But importance value of most herb species increased and significance of part of them had changed radically in community. The first most dominant species Eupatorium odoratum Linn. changed to the second most dominant while Microstegium vagans (Nees) A.Camus changed to be the first most important from the second most important species. The vegetation coverage was 100%.
