白枕鹤(Grus vipio)为大型涉禽,由于栖息地丧失,数量减少,已被CITES列为附录I,IUCN红皮书列为全球濒危物种,并被列为国家II级重点保护鸟类;2011年4~5月,笔者在七星河自然保护区对白枕鹤春季觅食地生境进行了调查;采用GPS定位技术和直接观察法对白枕鹤栖息生境进行测定,共获取70个1m×1m的样方,利用样方法和因子测定法测定其春季觅食地植物的类型、高度、盖度、植物密度、水深、人为干扰距离等.结果显示:白枕鹤春季主要在以苔草、小叶章为主的沼泽湿地中觅食;最佳觅食地植被高度为40~80cm,植被密度高于600株/m2,植被盖度为0~25%,觅食地水深多为5~15cm,人为干扰距离大于2000m;人为活动严影响着白枕鹤的觅食;春季白枕鹤有在火烧地中觅食的现象.
白枕鶴(Grus vipio)為大型涉禽,由于棲息地喪失,數量減少,已被CITES列為附錄I,IUCN紅皮書列為全毬瀕危物種,併被列為國傢II級重點保護鳥類;2011年4~5月,筆者在七星河自然保護區對白枕鶴春季覓食地生境進行瞭調查;採用GPS定位技術和直接觀察法對白枕鶴棲息生境進行測定,共穫取70箇1m×1m的樣方,利用樣方法和因子測定法測定其春季覓食地植物的類型、高度、蓋度、植物密度、水深、人為榦擾距離等.結果顯示:白枕鶴春季主要在以苔草、小葉章為主的沼澤濕地中覓食;最佳覓食地植被高度為40~80cm,植被密度高于600株/m2,植被蓋度為0~25%,覓食地水深多為5~15cm,人為榦擾距離大于2000m;人為活動嚴影響著白枕鶴的覓食;春季白枕鶴有在火燒地中覓食的現象.

White-napped Crane (Grus vipio)is a large wader. Because of habitat loss, its global population is declining and is now endangered. White -napped Crane is listed in CITES Appendix I (which bans all international trade in the species ) is categorized as Endangered in the IUCN Red list, and is also list-ed in the First Category of Protected Birds in China. During April to May 2011, the foraging habitat of White-napped Crane was investigated using GPS and direct observation at Qixinghe National Nature Reserve, Helongjiang Province. 70 plots (1m ×1m) were established for sampling vegetation. Factors of its foraging habitat including vegetation species, height, coverage, density, water depth and human disturbance were measured and analyzed by quadrate sampling and factor analysis methods. Results indicated that Grus vipio mainly foraging in the wetlands which have Carex spp., Calamagrostis angustifolia. The height of these plants was between 40cm to 80cm, the density was higher than 600 plants per square meter, vegetation cover was mainly between 0 and 25%, and the depth of the foraging place water was 5~15cm, the distance of human disturbance was greater than 1500m. Human activity greatly affects Grus vipio foraging. In spring, Grus vipio sometimes foraging in the burns down.
