摘　　要：在云南大山包黑颈鹤国家级自然保护区对越冬黑颈鹤(Grusnigricollis)的觅食地选择进行了观测,采用卡方检验和Bonferroni-Z分析法对观测结果进行分析,结果表明:越冬黑颈鹤对草地的利用为负选择,对草甸和农地的利用属于正选择,亚高山沼泽化草甸是越冬黑颈鹤主要选择和利用的生境.An observation on location selection for forage of Grus nigricollis has been conducted in Daoshanbao Black Neck Crane National Nature Reserve in Yunnan.
