啮齿动物群落稳定性影响机制

Mechanism of stability of rodent community

针对荒漠地区啮齿动物在不同干扰下群落稳定性影响机制的问题,通过主成分分析法、层次分析法、模糊综合评价法等一系列方法,综合分析了啮齿动物群落的稳定性与地上植物的生物量、种类、高度、盖度、密度等的关系,依托模糊综合评价模型,给出了啮齿动物群落稳定性的评估方法,定性并且定量地揭示了干扰对于啮齿动物群落稳定性的影响机制.

Aiming at the problem of the stability of rodent community under different disturbance in desert region, there are principal component analysis, analytic hierarchy process, fuzzy comprehensive evaluation and a series of methods being used. The relationship between the stability of the rodent community and the biomass, species, height, coverage, and density of the vegetation in the rodent community was analyzed. Based on the fuzzy comprehensive evaluation model, the evaluation method of rodent community stability is given, and the effect of disturbance on the stability of rodent community is qualitatively and quantitatively.
