摘要
2012年4月-2013年3月,在河南省郑州市,选择不同城市化程度的两个样地——郑东新区游园和人民公园,以麻雀(Passer montanus)为对象,采用可操纵实验法,分别以干扰方向、着装颜色、持物与否和移动速度为因素,每个因素2个水平,模拟4种不同方式的人为干扰,研究了其对麻雀警戒距离的影响.结果表明:4个因素在不同区域与不同季节均对麻雀的警戒距离具有显著影响;麻雀对高度城市化环境中的人类活动干扰具有较强的适应性.
From April of 2012 to March of 2013, two sites with different urbanization levels, Zhengdong Xinqu garden (ZXG) and Zhengzhou People's park (ZPP), were selected in Zhengzhou, Henan province, using manipulative experiment method, to investigate the vigilance distance (VD) of sparrows ( Passer montanus ) under human disturbances of four factors, i.e. approaching direction, clothes color, with or without something in hand, walking speed. The results showed that VDs of urban-garden-dwelling sparrows were significantly affected by human disturbance both in ZXG and ZPP. The results indicated that sparrows must have adapted to human influences in highly urbanized environment.
