矿质元素对东北马鹿冬季食物组成的影响

摘要

2010年12月至2013年1月，分析了马鹿种群（黑龙江穆棱东北红豆杉国家级自然保护区境内）冬季的食性和矿质元素对该地区马鹿冬季食物组分的影响。结果表明：保护区内，马鹿冬季以木本植物为主要食物；对东北红豆杉的大量取食，表明取样时期内马鹿种群可能存在营养限制。对矿质元素和食物组分的建模结果表明：铁和铜是影响马鹿食物组分的主要因素，其他矿质元素的影响并不显著。%The experiment was conducted to study the wintering food component and food mineral element content of red deer population in Muling Chinese Yew National Nature Reserve, and the influence of mineral element on food component dur-ing winter from December 2010 to January 2013.The red deer population is fed mainly on shrubs and trees.Appearance of needles in feces might indicate nutritional deficiency during sampling period.Iron and copper are the most influential min-eral elements on food component .There is no significant influence of other mineral elements on food component .
