摘　　要：巢穴为动物栖息、避敌和育幼提供了适宜的空间,了解动物巢址选择的特征对于物种的管理和保护有着重要的意义。为了解爬行类动物巢址选择的特征,以塔里木盆地的2种优势蜥种——新疆中部尉犁县叶城沙蜥(Phrynocephalus axillaris)和南疆沙蜥(Ph. forsythii)为研究对象,对巢址特征因子(巢穴温度、巢穴深度、巢穴湿度、巢口方向和巢口倾角)进行比较研究,探讨了2种沙蜥对巢穴选择的倾向性。结果表明:2种沙蜥均能在干旱的土壤中建巢,卵胎生的南疆沙蜥相比卵生的叶城沙蜥巢穴温度更低,巢倾角更大(p<0.05),但巢穴深度未达显著水平(p=0.126),二者对巢口方向均无明显偏好,具有随机性。研究结果进一步补充了塔里木盆地2种沙蜥的生态学资料,为后续巢址研究奠定基础。Nest provides space for inhabiting,shelter,and offspring nursery.Understanding characteristics of nest-site se⁃lection is therefore essential for species conservation and management.In order to investigate nest-site selection in rep⁃tiles,the nest-site characteristics(nest temperature,nest depth,nest humidity,orientation of nest entrance and nest angle)were quantified and the differences were compared between two sand lizard species(Phrynocephalus axillaris and Ph.forsythii)in Yuli County in the middle area of Xinjiang of China.Results showed that the two lizard species nested in relatively dry soil,with significantly lower nest temperature and higher nest angle in the ovoviviparous Ph.forsythia than that in the oviparous Ph.axillaris(p<0.05).The difference of nest depth between the two species was not significant(p=0.126),and they showed no preference for the orientation of nest entrance.This study provides compensating ecological data for Ph.axillaris and Ph.forsythia by comparing their nest-site features.As baseline information,it will also help with fu⁃ture detailed nest-site research.
