摘　　要：2008年3～6月,对长江师范学院校园白鹡鸰的生境分布和繁殖习性进行了初步研究。研究结果表明,白鹡鸰主要分布在地面草丛(57.41%)、水域(19.44%)、楼顶(16.67%)和疏林灌丛(6.48%),地面草丛成为白鹡鸰的最主要取食地;白鹡鸰的常见窝卵数为4枚,窝卵数为(4.00±0.32)枚,孵化期为(10.20±0.37)d,出雏数为(3.60±0.25)只,育雏期为(13.60±0.51)d;窝卵数与孵化期呈显著正相关(P=0.034,R2=0.757),两者呈幂函数关系,窝卵数与出雏数和育雏期相关性均不显著(P=0.166,P=0.550);白鹡鸰对校园生境表现出极强的适应性。The habitat distribution and reproductive habit of Motacilla alba in the campus of Yangtze Normal University from March to June of 2008 was preliminarily studied. The results showed that Motacilla alba distributed ground ＆ grassplot habitat （57. 41% ）, water area （19.44%） , building peak（ 16.67% ） and brushwood （6.48%）. ground ＆ grassplot habitat had been the most important foraging area. The common clutch size of Motacilla alba was four, with mean clutch size of （4.00 ± 0.32 ）, hatch period of （ 10.20 ± 0.37 ） d, fledglings number of （3.60 ±0.25 ）, fostering period of （13.60 ± 0.51 ） d. There were significant positive correlation between clutch size and hatch period （ P = 0. 034, R^2 = 0. 757 ） , which accorded to a power function relationship, and no significant effects between clutch size and fostering period （P = 0. 166 ,P = 0. 550） . Motacilla alba had strong adaptation to habitat in campus.
