摘要
本文采用粪便显微组织学分析技术，分析了呼伦贝尔草原黄羊与放牧绵羊冬季采食植物的种类组成和比例，探讨了黄羊与放牧家羊冬季对食物资源利用的关系。研究表明，黄羊与放牧家羊冬季采食的植物均以禾本科、豆科等草本植物为主，二者在冬季对食物资源利用的重叠性较大，相似性系数ＰＳ＝０．７８９。
Winter food-habits of Mongolian gazella(Procapra gutturosa)and inquire into using relationship of food resources between mongolian gazella and domestic sheeps was stud-ied with the microhistological analysis technique of feces in Hulun-beir grassland from1993-1994 winter. The results showed that 21 species(genera) plants are used by mongolian gazellathrough the winter, gramineae constitute 74.8%,fabaceae constilute 12.1%,22species(genera)plants are eaten by domestic sheeps,gramineae constitute 73.3%,fabaceae 11.6%. The plants eaten by mongolia gazella and domastic sheeps are mainly gramineae andfabacear in winter,the index of percent are PS=0.789.
