摘    要:2002—2008年4—5月,采用定点观察、GPS定位、样方调查和因子分析等方法,研究了扎龙湿地白枕鹤孵化期对觅食生境的选择.结果表明:在孵化期,研究区白枕鹤的觅食生境类型主要为芦苇沼泽(74.36%),觅食生境的选择以标识因素和能量因素为主,其次是可觅性因素、安全距离因素和隐蔽因素;扎龙湿地白枕鹤孵化期的觅食生境类型多样化,以湿地(芦苇沼泽)为主,兼含陆地(农田);白枕鹤孵化期的觅食生境包括生境标识、食物、水和隐蔽物四大要素,其对觅食生境的选择分2个层次(大生境层次和小生境层次)3个过程(觅食生境类型选择、觅食区选择、觅食微生境选择).

关 键 词:白枕鹤  孵化期  觅食生境选择  扎龙湿地

Abstract:By using the methods of fixed-spot observation, GPS positioning, sampling plot investigation, and factor analysis, the forage habitat selection of white-naped crane (Grus vipio) during its incubation period in Zhalong Wetland was studied from April to May 2002-2008. In the study area, the crane during its incubation period chose a variety of habitat types as its forage habitat, among which, wetland (reed swamp) was the main one, occupying 74.36% of the total, followed by farmland. The forage habitat included four elements, i.e., habitat identification, food, water, and cover, and the main selection criteria were the identification factor and energy factor, followed by eating feasibility factor, security distance factor, and concealment factor. The forage habitat selection of the crane during its incubation period had two levels (macro- and microhabitat) and three courses (forage habitat type choice, forage area choice, and forage microhabitat choice).
Keywords:white-naped crane  incubation period  forage habitat selection  Zhalong wetland
