中文摘要:2008年3月至5月初,采用样方法对山东曲阜大沂河流域的鸻鹬类进行了调查。共记录8种鸻鹬类,隶属3科4属。发现保留了天然地貌的河道比人工改造的河道更适宜鸻鹬类栖息;天然河道中,水面积比例为0.4和0.6的生境更吸引鸻鹬类,鸻鹬类数量随着青草覆盖率的增加而上升;人为干扰对鸻鹬类的数量有显著影响,充分的隐蔽条件会降低人为干扰对鸻鹬类的影响。保护大沂河的鸻鹬类多样性将为曲阜市的生态保护提供科学依据,并为南四湖流域的生物多样性保护提供有益经验。
英文摘要:Using plot transects, a survey of waders was conducted along Dayi River of Qufu from March to early May in 2008. A total of 8 waders species were recorded, which belonged to 4 genera and 3 families. The results showed that: areas that retained the natural topography were more suitable habitat for waders, as compared to artificially modified waterways. Along natural waterways, waders preferred habitats where the water area proportion was 0.4 and 0.6. The number of birds increased along with the rising coverage of grass. Human-disturbance influenced wader numbers obviously. The ideal covert condition would reduce the amount of human-disturbance. Wader biodiversity increasing by habitat conservation of Dayi River would provide a scientific basis for ecological protection of Qufu city, and a benefit to biodiversity conservation in the Nansi Lake drainage area.
