目的 调查和了解卡拉麦里山自然保护区赤颊黄鼠巢域微生境的选择及与主要环境因素关系.方法 2019年春、夏季,布设5 mx5 m样方,调查赤颊黄鼠活动穴居地52个,对照样方55个,分析穴居地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.对数值型生态因子数据分别进行描述性统计分析,生态因子差异采用两独立样本Mann-Whitey U检验或独立样本t检验;对非数值型生态因子数据进行2个等级变量间的相关分析.通过主成分分析确定在赤颊黄鼠微生境选择上起主要作用的生境因子.结果 影响赤颊黄鼠穴居地微生境选择的主要因素是海拔高度和土壤含水率2个生态因子(均P＜0.01);主成分分析显示影响赤颊黄鼠穴居地微生境选择的环境因子依次是植被盖度(权系数为0.920)、草本盖度(权系数0.863)、灌木盖度(权系数为0.778)和灌木种数(权系数为0.768).结论 赤颊黄鼠倾向于选择海拔高、土壤含水率低、平滩类型的微生境作为穴居地.研究为赤颊黄鼠的科学防控提供重要理论依据.
Microhabitat selection in burrowing area of Spermophilus erythrogenys in Mt.Kalamaili Ungulate Nature Reserve,Xinjiang Uygur Autonomous Region
Objective To investigate the microhabitat selection for burrows of Spermophilus erythrogenys and the effects of major environmental factors in the Mt.Kalamaili Ungulate Nature Reserve,China.Methods In the spring and summer of 2019,52 active burrows of S.erythrogenys and 55 control quadrats were investigated with each quadrat measuring 5 m×5 m,for comparisons of habitat factors such as elevation,slope,the number of plant species,vegetation coverage,and biomass.Descriptive statistical analysis was performed on the numerical ecological factor data,and the difference of ecological factors was determined by Mann-Whitey U test or independent sample t-test.The correlation analysis between the two level variables was carried out on the non-numerical ecological factor data.Principal component analysis(PCA)was used to determine the habitat factors that played a major role in the selection of microhabitats in S.erythrogenys.Results The main factors affecting microhabitat selection of S.erythrogenys in the burrowing area were elevation and the soil moisture content(all P＜0.01).The principal component analysis showed that the environmental factors influencing S.erythrogenys burrow microhabitat selection were vegetation coverage(weight coefficient=0.920),herb coverage(weight coefficient=0.863),shrub coverage(weight coefficient=0.778),and the number of shrub species(weight coefficient=0.768).Conclusions S.erythrogenys prefers microhabitats of high elevation,low soil moisture content,and the flat beach type as burrows.The results of this study can provide an important theoretical basis for the scientific control of S.erythrogenys.
