| 摘 要： | 松山自然保护区是北京市国家级的自然保护区。在保护区内,对7种生境中的鼠类群落结构进行了研究,并用x~2适合度检验分析了鼠类群落,以及其中优势种对环境的适应性及群落的多样性和均匀性指数进行了分析。对比了各群落间的特点,发现鼠类群落随海拔高度的不同而有明显的不同。

| Abstract: | Songshan mountainous region is one of the national nature sanctuary inBeijing. In this paper, the structures of rodent communities in seven bio- types are discussed. The dominant species of the rodent communities andtheir adaptive habits are analysed by Chi-squared. The similarity indexesbetween the communities are also calculated. Camparing the characteristicsof the comminities, it is discovered that the communities vary with differentaltitudes. |
