- 摘要:
- 山体滑坡是卧龙自然保护区常见自然灾害，多由山区大雨或地震灾害引起。利用样方法对11个卧龙自然保护区滑坡山体自然恢复5 a后的植被进行调查，并选取一个人工恢复样地为对照，研究滑坡区域次生群落的物种组成、区系成分和先锋物种。调查区域内分布有植物44科103属119种，其中灌木29种，草本90种，包括卧龙植物普查未发现的新记录植物18种。被子植物在科、属、种数均占绝对优势。区系成分分析显示植被自然恢复早期的39科种子植物分属5种地理成分，以世界广布的科数量最多；同时对作为区系地理分类依据“属”的分析显示，98属种子植物可划分为11种分布类型，其中温带分布类型的属占非世界分布属数的90.91%，说明调查区域植被具有温带性质。自然恢复样地的群落结构和物种丰富度明显优于人工恢复样地，通过重要值计算确定不同自然恢复边坡灌木层和草本层优势先锋物种，为卧龙未来滑坡山体人工植被恢复的本地物种选择提供科学依据。
- Abstract:
- Landslide is a common geological hazard and mainly triggered by heavy rain storm or earthquake in Wolong mountainous region. In this paper the vegetation of 11 landslide areas after five-year of natural restoration were investigated using quadrat method in Wolong nature reserve. Moreover, the species composition, floristic element and pioneer species of the secondary communities were analyzed, and an artificial restoration area was chosen as the control. 44 families and 103 genera of 119 plant species, including 29 species of shrubs and 90 species of herbs were detected, including 18 new species which had not been recorded before. Angiosperm was dominant in numbers of families, genera and species. The geographical elements of detected 39 families of seed plant at the early stage of the natural restoration mostly were cosmopolitan out of five geographical elements. All 98 genera of seed plant were divided into 11 types by their geographical elements. Using genus as the basis of floristic element classification, 90.91% of the seed plant were temperate genera (excluding the cosmopolitan genera), indicating the sample areas were temperate property. The results indicated that the species abundance and community structure of natural restoration areas were superior to the artificial recovering area. The dominant pioneer species of shrub layers and herb layers of different natural restoration landslide areas were ascertained via the analysis of importance value. This research provides scientific basis for candidate native species could be used in ecological artificial vegetation restoration in Wolong nature reserve areas in future.
