摘　　要：目的研究黑线仓鼠的食物组成,分析食物结构的动态发生规律,为制定科学的防治对策及可持续治理技术方案奠定理论基础。方法 2003年6-10月和2004年3-5月,在内蒙古锡林郭勒盟浑善达克地区,采用夹线取样法捕获黑线仓鼠,对捕获鼠颊囊内植物种子和胃内容物进行鉴定和分析,研究浑善达克沙地黑线仓鼠的食性及其动态。结果在研究地区,沙地植物种子为黑线仓鼠的主要取食物,占食物组成的55%以上,其余部分为昆虫与植物茎叶;在沙地昆虫资源多的月份,黑线仓鼠存贮大量昆虫。结论沙地植物种子为黑线仓鼠的主要取食物,随着沙地种子成熟时间、种子资源蕴藏量不同,黑线仓鼠的食性表现出季节性。Objective To investigate the diet of striped hamster （Cricetulus barabensis） and its dynamic changes, and to provide a theoretical foundation for the development of scientific control measures and sustainable management strategy. Methods Killing-trap method was used monthly to capture C. barabensis in the Hunshandake desert in Inner Mongolia, China. The diet of trapped striped hamsters was analyzed by identification of the seeds stored in the cheek pouches and stomach of each individual. The diet of C. barabensis was studied in Inner Mongolia Research Station. Results The seeds of sandy plants contributed to more than 55% of the food items of C. barabensis. Cricetulus barabensis also took leaves and stems of plants. Cricetulus barabensis stored a large number of insects during certain months when insect resources were abundant. Conclusion Plant seeds are the main diet of desert hamsters. The food composition of C. barabensis changes with the maturation of plants and reservoir of seed resources.
