| 摘 要： | 2006年12月～2007年2月,采用秩变换分析法对北京野鸭湖湿地自然保护区越冬灰鹤群的觅食栖息地选择规律进行了研究.在保护区18种土地利用类型中,灰鹤的觅食柄息地主要为玉米地、沼泽草甸、水库冰面和草场等4种.越冬灰鹤对玉米地的选择性最高,草场的选择性最低,说明北京地区越冬灰鹤对人类活动的依赖性很大.同时发现,烧荒、翻地等耕作方式会大大降低食物的可获得性,影响灰鹤的觅食效率.

| Abstract: | From December 2006 to February 2007,the wintering habitat selection of common crane was studied by the order transform analyze in Beijing Yeyahu wetland nature reserve.In the 18 land types in Yeyahu,there were 4 types of the main foraging habitat,corn field,marsh,reservoir ice and grassland.Corn field was the most important foraging habitat,and grassland was the least used.The results showed the common crane's foraging depend on human activities more than other factors.We also found firing and digging corn ... |
