郑州郊区崖沙燕的洞巢空间分布格局

The Spatial Distribution Pattern of Sand Martin(Riparia riparia) Nest in the Suburbs of Zhengzhou,Henan

2014年3—8月,采用样方法对分布于河南省郑州市郊区的两处崖沙燕营巢地的洞巢进行了调查,对获得的数据进行差异显著性检验及单因素方差分析。结果表明:(1)两处崖沙燕营巢地中的洞巢数量差异显著(P<0.001);(2)崖沙燕的洞巢数量在垂直方向上差异不显著(P=0.560),巢间距差异显著(P<0.05);(3)崖沙燕洞巢的分布类型,东区营巢地为聚集型分布模式,西区营巢地为均匀型分布模式;(4)崖沙燕洞巢的洞口大小随时间变化与营巢地有关。建议在城市化建设过程中依据崖沙燕的洞巢空间分布格局特点对该物种进行合理的保护。

We studied two nest-sites(east area EA and west area WA)of sand martin(Riparia riparia)in the suburb of Zhengzhou,Henan Province,using a plot method based on field observations from March to August 2014.We compared means by use of one-way ANOVA.The total numbers of nest-holes differed significantly between two nest-sites(P<0.001).2)In vertical direction,nest number is similar(P=0.560),but distance between nests differ significantly(P<0.05).3)By distribution pattern,it was aggregated in the EA nest-site,and uniform distribution in the WA nest-site.4)The hole size of nests changed with time which related to nesting place.We suggest that protection of the sand martin be according to its nest-site structure and distribution pattern characteristics within the process of urban development.
