| 摘 要： | 坝周低山区是金沙江干热河谷生态环境最为脆弱的地带,而泥岩坡地植被恢复又是坝周低山丘陵区植被恢复的难点。在中科院元谋水土保持生态试验站进行了泥岩坡地的封禁植被恢复、半封禁植被恢复及人工植被恢复试验,并对比分析不同植被恢复方式对植物群落的影响。结果表明,封禁、半封禁和人工促进的植被恢复方法都能促进干热河谷区植被恢复与重建,植物群落的高度、盖度和生物量均有改善,而封禁恢复可能带来相对丰富的物种多样性。

| Abstract: | The eco-environment of low mountain area is the most fragile in Jinsha River hot-dry valley.And it is also one of the most difficulties to improve the vegetation coverage,biomass and biodiversity for a degraded mudstone slope.Some tests of vegetation rehabilitation,including closure,semi-closure and artificial vegetation rehabilitation are implemented in Yuanmou soil and water conservation ecological experimental station,Chinese academy of sciences.Then the impact of the different measures to vegetation reh... |
