摘要
[目的]明确荒漠区在不同干扰下植物因子与啮齿动物优势物种之间的相互影响.[方法]研究西北某干旱地区轮牧与过牧干扰下啮齿动物优势种种群的生物量和植物因子之间的关系,并进行灰色关联度及回归分析.[结果]优势物种三趾跳鼠、子午沙鼠和小毛足鼠均与灌木植物有较高的关联度,植物因子对该地区优势鼠种生物量的作用有明显差异,从而形成相互适应、长期共存的格局.[结论]揭示了植物生物量与啮齿动物生物量的变化关系,为研究该荒漠区啮齿动物优势物种群落分布规律提供了参考.
Abstract
[Objective] The aim was to study the interaction effect between plant factors and dominant species of rodents in desert region under different disturbance.[Method] The relationship between biomass of rodent dominant species and plant factors under rotational gazing and overgrazing disturbance in desearch region in northwest region was studied,the grey correlation degree and regression analysis was conducted.[Result] The dominant species like three-toed Jerboa,Meriones meridianus and Xiaomao foot mouse had higher correlation with shrub plants.Plant factors had obvious differences on biomass of dominant species,thus forming the pattern of mutual adaptation,long-term coexistence.[Conclusion] The relationship between plant biomass and the biomass of rodents is revealed,which provides reference for study on distribution law of dominant species of rodent in desert region.
