| 摘 要： | 对江苏盐城黑嘴鸥繁殖期觅食地和营巢地及其主要特征进行了调查，黑嘴鸥繁殖觅食地有盐田，碱蓬滩，草滩，水产品养殖塘，农田，泥质滩涂及河口港汊7种类型，生境选择的结果表明黑嘴鸥对碱蓬滩涂和泥质滩涂都有正选择性，对农田和河口港汊具有负选择性，繁殖前期对养殖塘具有正选择性，不同繁殖时期黑嘴鸥对碱蓬滩和养殖塘的利用情况变化最明显，两年中，黑嘴鸥对河口港汊的利用情况稳定，黑嘴鸥营巢地有獐毛滩，碱蓬滩和大米草滩3种类型，其中碱蓬滩是其主要营巢栖息地，对巢址选择因子的分析的结果表明：影响黑嘴鸥巢址选择的因子主要有4类，依次为：植被盖度和群集度，人为活动干扰强度，底栖生物量及距水源距离，其贡献率分别为26．23％，20．55％，14．82％，14．02％。

| Abstract: | This article shows the characteristics of foraging and nesting habitats for Saunders' Gull ( Larus saundersi ) in Yancheng Biosphere Reserve. Seven types of foraging habitats for Saunders' Gull were recorded: saltworks, Suaeda yhaura beaches, tidal grassland, aquatic ponds, farmlands, tidal mud-field, and rivers and streams. We compared the habitat availability with utilization in these seven habitats. The results showed that Suaeda yhaura beaches and tidal mud-fields were positively selected by Saunders' G... |
