摘　　要：2014年3—8月,采用样方法对分布于河南省郑州市郊区的4处崖沙燕(Riparia riparia Linnaeus 1758)营巢地的13个生境因子进行了调查,测定了巢址样方和对照样方各160组数据,并利用Mann-Whitney U检验对这些数据的显著水平进行了检验;最后采用逐步判别分析(stepwise discriminate analysis)方法确定影响崖沙燕巢址选择的主要生态因子,并建立了标准化的典则判别函数。结果表明,1)崖沙燕洞巢的洞口横径(8.46±0.79)cm,纵径(8.30±0.79)cm,巢洞深(87.80±11.97)cm,巢室长径(11.25±1.33)cm,短径(10.43±1.33)cm,巢室高(9.99±1.33)cm;2)巢址样方与对照样方在植被均高、植被密度、坡位、坡度、崖高、崖长、崖龄及干扰度等8个方面差异达到显著水平,崖沙燕偏好选择的洞巢周围植被较高(97.24±8.42)cm,植被密度较大(64.34±7.15)株/m^2,坡度较大(83.78±0.35)°、上坡位(1.41±0.04)、崖较高处(7.54±0.13)m、崖壁较长(51.18±3.54)m、崖龄较短(2.41±0.05)月及人类干扰较低(1.94±0.06);3)逐步判别分析结果表明,影响崖沙燕营巢地选择的主要生境因子是坡位、崖龄和干扰度,标准化的典则判别函数为y=0.753×坡位+0.681×崖龄+0.288×干扰度。建议在城市化建设过程中针对崖沙燕的巢址选择特性建立合理的保护措施。Bird nest-site selection is an important topic in avian ecology, especially with respect to bird reproduction success. In the past decades, urban avian ecology has attracted more attention, because determination of how birds adapt to urban areas could improve the ecological functioning of urban ecosystems and help to build a better living environment for both the human being and urban wildlife. Sand martin （ Riparia riparia Linnaeus 1758 ）, a bird species belonging to Passeriformes, Hirundinidae, Riparia, is distributed throughout the world except for Australia. In recent years, sand martins have become an urban bird that can reproduce in Zhengzhou City, Henan Province, the People＇s Republic of China. The sand martin predates Diptera, mosquitoes, and other insects, and therefore plays an important role in eliminating insect pests from urban environments and maintaining ecological stability in cities. However, in the Zhengzhou suburb, there is a conflict between human urbanization and sand martin nest-site selection. Sand martin nest-sites are mainly located on vertical sections of cliffs, which are formed by new mining tunnels or by the hillock formed after bulldozers backfill the tunnel base. To alleviate the conflict and promote eco-city construction, it is necessary to understand the habitat characteristics of the sand martin and the dominant factors affecting its nest-site selection. A survey was conducted to study the nest-site selection of four sand martins in the suburb of Zhengzhou, using a plot method based on field observations from March to August 2014. For either burrow nests or control areas, a total of 160 data sets were collected, and Mann-Whitney U test was adopted to analyze the data. The main ecological factors affecting sand martin nest- site selection were determined by stepwise discriminate analysis, and the Standardized Canonical Discriminant Function was formed. The results showed that 1 ） the nest hole diameter was （8.46±0.79） cm, longitudinal diameter was （8.30±0.79） cm,
