摘    要:2007年6~8月在内蒙古中部中蒙边境地区,使用粪便显微组织学分析方法并结合野外食痕调查,对蒙古野驴(Equus hemionus hemionus)的夏季食性进行了分析研究。结果表明,蒙古野驴夏季共计采食11科21种植物。在夏季食物组成中克氏针茅(48.61%)、芨芨草(16.00%)、寸草苔(7.51%)共占食物组成的72.12%,是蒙古野驴夏季的主要食物,其中克氏针茅是其大宗食物。蒙古野驴对克氏针茅、芨芨草、画眉草、糙影子草、草木樨状黄芪等12种植物有正选择性,对狗尾草、盐爪爪、荒漠锦鸡儿、栊牛儿苗、四舍木等9种植物有负选择性。蒙古野驴自身的特点及植物质量会影响其夏季食性及食物的选择性。

关 键 词:蒙古野驴  食性  粪便显微组织学分析

Abstract:The summer food-habit of Asiatic wild ass ( Eqqus hemionus hemionus) was studied by combining fecal microscopic analysis with field survey of feeding sites from June to August, 2007 in Inner Mongolia. Results showed that total of 21plant species belonging to 11 families were foraged during summer. Stipa krylovii ( 48.61% ), Achnatherum splendens ( 16.00% ) , Carex duriuscula (7.51%) were the main components in summer diet, occupying 72.12% of all plants used. Asiatic wild ass had positive selectivity for 12 plant species like Stipa krylovii, Achnatherurn splendens, Eragrostis pilosa, Cleistogenes squarrosa, Astragalus melilotoides etc and negative selectivity for 9 plant species like Setaria viridis , Kalidium foliatum , Caragana roborovskyi , Erodium stephanianum , Tetratan nwngolica etc. The traits of Asiatic wild ass and plant quality can influence summer food-habits and diet selectivity.
Keywords:Asiatic wild ass (Equus hemionus hemionus)  food-habit  fecal microscopy analysis
