摘　　要：山地麻蜥年产多窝卵。窝卵数、窝卵重和卵重与雌体体长呈正相关,卵重与窝卵数无关。窝卵数、窝卵重和卵重不存在明显的季节变化。卵长径与卵短径呈正相关,卵长径、卵短径与窝卵数无关。雌体通过增加窝卵数和卵大小增加繁殖输出。孵出幼体的体重、体长、尾长、躯干干重、剩余卵黄不存在季节差异,但5月份孵出幼体的脂肪体高于4月份。Eremias breuchleyi was a multiple-clutched lizard laying eggs from 2 to 6 per clutch. No seasonal shifts in clutch size,clutch mass and egg mass were found and three variables were positively correlated with maternal size(SVL). Egg mass, egg length and egg width was independent of clutch size,respctively. Egg length was positively correlated with egg width. Females increased reproductive output mainly through increasing clutch size and egg size.The data revealed that variation in season had no important effects on body size and shape of Eremias breuchleyi hatchlings.
