摘　　要：本文对北美Ｃｈｉｈｕａｈｕａｎ荒漠由４科７属１７种啮齿动物组成的群落的能量和分配比例的时间序列资料，利用相关分析方法比较了群落能量在１７个物种种群中分配方式的动态和季节性。结果表明，虽然各物种种群的能量分配随环境的变化而变化，但分配比例却保持相对稳定，且９８％以上的能量是以协调的方式在群落内的各物种间进行分配的。协调的能量分配方式则使恶劣多变的荒漠生境中的啮齿动物群落的能量动态保持着相对稳定。Abstract Data are presented on time series of energy allocation and allocation proportion of the rodent community,whichis consisted of l7 species,7genera, 4 families, in the Chihuahuan Desert. Correlation analyses are used to comparedynamics and seasonality of energy allocation among l7 species population. The results show that the allecation pro-portion was kept relative stable though energy allocation among the 1 7 species fluctuated responding to the abioticenvironment.Of the total energy of the community,98 % was allocated in a harmonized way. And the harmonizedenergy allocation kept energy dynamics of the redent community relatively stable in the fluctuated and unpredictable environment.
