Abstract: Objective To study the relationship between microhabitats of Rhombomys opimus nest area and environmental factors in the desert area of the Mount Kalamaili Ungulate Nature Reserve, China, and investigate the factors affecting the selection of the nest domain of R. opimus, and to provide a basis for rodent control. Methods In the spring and summer of 2019 and spring, summer, and autumn of 2020, we investigated habitat factors (including elevation, slope, the number of plant species, vegetation coverage, and biomass) in 111 R. opimus home range quadrats and 111 control quadrats (without R. opimus). A quadrat was 5 m×5 m in size. Results Three ecological factors significantly affected the selection of microhabitats of R. opimus nest area:elevation, soil moisture content, and plant species number (all P<0.05). Principal component analysis showed that the main factors affecting the selection of microhabitats of R. opimus nest area were vegetation coverage (0.863), distance from roads (0.761), distance from residential areas (0.734), and shrub coverage (0.719). Conclusion The home range of great gerbils tends to have high elevation, low soil moisture content, diverse plant species, flat beach (including sandy and alkaline soil substrates), high vegetation coverage, and high shrub coverage, and be far away from human settlements and roads. The results can provide an important theoretical basis for the scientific control of great gerbils.

摘要: 目的 研究卡拉麦里山自然保护区荒漠区大沙鼠巢域微生境与环境因素关系,了解大沙鼠巢域选择的影响因素,为鼠害防控提供依据。方法 在2019年春、夏季及2020年春、夏和秋季,设置并调查5 m×5 m大沙鼠活动巢域样方111个,无大沙鼠活动巢域的对照样方111个。分析比较巢域微生境和对照样方的海拔、坡度、植物种数、植被盖度、生物量等生境因子。结果 影响大沙鼠巢域微生境选择依次是海拔、土壤含水率和植物种数3个生境因子,其差异均有统计学意义(均P<0.05)。主成分分析表明影响大沙鼠巢域微生境选择的主要因子依次是植被盖度(0.863)、距道路距离(0.761)、距居民点距离(0.734)、灌木盖度(0.719)。结论 大沙鼠倾向于选择海拔高、土壤含水率低、植物种数多、平滩区域(包含砂质土和碱土2种土壤基质),植被盖度高,灌木盖度高,远离居民点和道路等人为干扰少的微生境作为巢域。研究结果可为大沙鼠的科学防控提供重要的理论依据。
