食肉动物食性研究方法评价

粪便分析法是食肉动物食性研究的基础上方法，采用频率法和剩余物相对干质量法对内蒙古东部地区的狼和大兴安岭地区的紫貂食性进行了研究。结果表明。频率法不能很好地体现出各食物类型在食谱中的相对重要性。

Evaluation on the Studying Methods of Carnivore Food Habits

Seats-analysis is the principal method in the study of carnivore food habits. In this paper. thefrequency of occurrence (FO) and the relative tveight of remains of prey types (RW) were used to studyfoe feeding habits of wolves in inner Mongolia and sables in Daxing'an Mountains. Comparative resultsindicated that the FO cannot show the relative importance of every food type. the large-scale prey isalways underestimited. but FO is very simple and easily used. The RW can accurately show the fact andindicate the relative importance of every prey.
