中文摘要为了研究农田啮齿动物群落的动态规律,用标志重捕的方法给出了川西平原农田的啮齿动物群落的物种数、结合种群密度、生物量、物种多样性的Shannon指数与Simpson指数等5个变量的时间序列资料,并分析了这些时间序列的年间变动和季节变动的特点。结果表明:(1)5个变量总是处于不断的变化之中,特别是年间交替升降十分明显;(2)群落的全部8个物种从未同时出现过,同一个月最多有5个物种,最少只有1个物种;(3)5个变量季节变动的幅度均较大并各具有1至3个不等的明显的峰值,而年间变动的幅度则相对较小;(4)5个变量的最大值均出现在夏季,最小值则出现在春季、夏季或冬季;(5)5个变量的季节性均不强;(6)优势种大足鼠(Rattusnitidus)的种群密度分别与群落结合种群密度、生物量的年间变动和季节变动均具有相似的变动规律;此外,优势种大足鼠的种群密度、生物量分别占群落结合种群密度、生物量的比例均较高,而且这两个比例季节变动的幅度都较大而年间变动则较为稳定。
英文摘要The time series of the 5 variables, including number of species, joint population density, biomass, Shannon index and Simpson index of species diversity of the rodent community , which was composed of 487 individuals of 8 species of 4 genera of Muridae in cropland of the Western Sichuan Plain from 1989 through 1995, are presented for studying the dynamics of the rodent community in the cropland by mark-recapture. Then, both interannual and seasonal fluctuations of the time series of these variables are analyzed and com- pared.Finally , the dynamics of the rodent community in the 7 years are summarized. The rodent community was concluded as the following:1)all of the 5 variables fluctuated interannually and seasonally during the 7 years;2)all of the 8 species of rodents never occurred in the rodent community in the same month, with the maximum of number of species 5 and the minimum 1;3)the seasonal fluctuations of the 5 variables were greater than their interannual fluctuations, respectively , peaked from 1 to 3 in a year; 4)each of the 5 variables had its maximum only in some summers during the 7 years, but had its minimum in some winters or springs and sometimes even in some summers;5) none of the 5 variables showed remarkable seasonality ;6) the seasonal fluctuations of the proportions of the population density and biomass of the domi- nant species (Rattusnitidus)respectively in the joint population density and biomassof the rodent community were greater than its interannual fluctuations, and both the interannual and seasonal fluctuations of the popula- tion density of the dominant species (Rattus nitidus)were much similar to those of joint population density and biomass of the rodent community .
