| 摘 要： | 运用组平均聚类法,以啮齿动物密度和生物量综合决定的重要值为数据,对延安林区啮齿类群落进行聚类分析.根据聚类结果,延安林区啮齿动物可划分为3个群落,人工林区达乌尔鼠兔Ochotona daurica 中华鼢鼠Myospalax fontanieri群落(群落A);自然次生林区大仓鼠Cricetulus triton 中华鼢鼠 大林姬鼠Apodemus peninsulae群落(群落B);林缘农田区中华鼢鼠 小家鼠Mus musculus 长尾仓鼠Cricetulus longicaudatus群落(群落C).结果较全面反映了群落的组成以及群落生境,群落多样性指数以群落A最高(1.8665),群落B次之(1.6516),群落C最低(1.2095).多样性分析表明,啮齿动物群落多样性和环境的复杂性与稳定性密切相关.图1表3参10

| Abstract: | .Based on the importance value of rodents, the rodent communities in Yan'an forest region are classified by group average clustering analysis. The rodents can be divided into 3 communities: Ochotona daurica Myospalax fontanieri cansus community (Community A) in planted forest region; Cricetulus triton Myospalax fontanieri cansus Apodemus peninsulae community (Community B) in natural secondary forest region; Myospalax fontanieri cansus Mus musculus Cricetulus longicaudatus community (Community C) in cropland region near forest. The results represent the composition and niches of the communities. Species diversity indexes of different commununities are different: the highest index is in community A (1.866 5), the next in community B (1.651 6) and the lowest in community C (1.209 5). The result of diversity analysis indicates that the diversity of rodent communities has a close relationship with the complexity and stability of their surroundings. The results can be used as a reference for the protection of the plants, the prevention and control of the harmful rodents in Yan'an forest region. |
