| 摘 要： | 2005 ～2006 年草青期和草枯期我们在青海省天峻地区随机收集了藏原羚的粪样,并利用粪便显微分析法对藏原羚的食性进行了研究。结果表明,藏原羚采食共计16 科34 属43 种植物,其中草青期采食16 科33 属42种,草枯期12 科22 属30 种。豆科植物是藏原羚采食的主要类群,禾本科、菊科、蔷薇科和莎草科其次,豆科、禾本科、菊科、蔷薇科和莎草科等五科植物占藏原羚采食总量的90% 左右。不同物候期,藏原羚的食性变化明显,豆科、蔷薇科在草枯期所占的比例显著低于草青期,而禾本科、菊科和莎草科所占比例则显著高于草青期。

| Abstract: | A systematic study of the diet of Tibetan gazelles (Procapra picticaudata) was completed by microscopic fecal analysis from 2005 and 2006 in Tanjun area,Qinghai province,China. We identified 43 plant species in the fecal samples of Tibetan gazelles in the experiments, representing 34 genera and 16 families. The gazelle grazed on 42 species representing 33 genera and 16 families during the green-plant period but only foraged on 30 species from 22 genera and 12 families during the withered-plant period. Leguminosae were the largest part of the diet, comprising 52.7%, of the diet of Tibetan gazelle during the green-plant period and 38.5% during withered-plant period. Besides Leguminosae, four other families, the Gramineae, Compositae, Rosaceae and Cyperaceae, were mainly foraged by Tibetan gazelle. Food from the above five families made up about 90% of the diet of Tibetan gazelle. Diet compositions of Tibetan gazelle changed greatly from the green-plant period to the withered-plant period. Proportions of Leguminosae and Rosaceae decreased significantly while proportions of Gramineae, Compositae and Cyperaceae increased significantly. |
