| 摘要: |
| 选择滇东南生境破碎化的木美地下河流域,采用常规样方调查法对人口聚居区植被进行研究。木美地下河流域的植被可划分为常绿-落叶阔叶混交林、暧性石灰岩灌丛和中草草丛三种类型。流域内的植被以灌丛为主,破坏严重,分布零星,且均呈向山脊收缩的特点,主要干扰因素是伐薪。流域内植物群落的演替同时存在顺向演替和逆向演替,退化还是恢复的决定因素是砍伐压力和砍伐利用方式。通过优化砍伐利用方式结合沼气能源的兴建,可以在持续伐薪的情况下实现植被自然恢复。破碎化生境中残存的植被在生物多样性保护和利用,以及植被恢复过程中具有重要作用。 |

| Abstract: |
| The article studied the actuality and features of the vegetation in fragmental habitats in a typical karst area of Mumei underground river drainage in southeast Yunnan province.The vegetation in the underground river drainage can be classified into three types:evergreen deciduous broadleaved mixed forest,warm karst shrubbery and mid-height hassock.All of them have been degrading because of human activities.The author also discusses the trend of community succession and the possibility of vegetation rehabilitation. |
