| 摘 要： | 对贺兰山同域分布的高山麝和阿拉善马鹿秋季的粪便进行采集,利用粪便显微分析法对二者秋季食性进行了研究。分别采集高山麝和阿拉善马鹿活动区域内粪样和植物样本,分别获得两种动物40个复合粪便样本,采用频率转换法对数据处理计算,得到贺兰山同域分布的高山麝和阿拉善马鹿秋季的食性组成及组成比例。结果显示,高山麝秋季共取食植物20科30种(属),其中蓝锭果忍冬(11.96%)、秦氏黄芪(10.17%)、密齿柳(8.32%)、折枝绣线菊(6.82%)、内蒙野丁香(6.18%)组成了高山麝的主要食物;阿拉善马鹿秋季共取食植物12科29种(属),其中针茅(22.15%)、灰榆(21.14%)、早熟禾(16.90%)、小叶金露梅(11.62%)、山杨(10.00%)为阿拉善马鹿秋季的主要食物。高山麝和阿拉善马鹿共有9种食物重叠,生态位重叠指数为83.75%。秋季高山麝取食的Shannon-Wiener指数、Pieou均匀性指数、食物生态位宽度指数和最大的物种多样性指数均高于阿拉善马鹿。

| Abstract: | The feces of Alpine musk deer (Moschus chrysogaster) and Alashan red deer (Cervus alashanicus) were collected in the Helan Mountains, and their feeding habits in autumn were studied by microscopic analysis of the feces. The fecal samples and plant samples were collected from the habitats of Alpine musk deer and Alashan red deer, and 40 compound samples were obtained for each species. The autumn diet proportions of Alpine musk deer and Alashan red deer were processed using the frequency conversion method. The results showed that the diet of the Alpine musk deer consisted of 30 species of 20 families in autumn, including Lonicera edulis (11.96%), Astragalus spp. (10.17%), Salix characta (8.32%), Spiraea spp. (6.82%), and Leptodermis ordosica (6.18%). The diet of the Alashan red deer consisted of 29 species of 12 families, including Stipa spp. (22.15%), Ulmus glaucescens (21.14%), Poa spp. (16.90%), Potentilla parvifolia (11.62%), and Populus davidiana (10.00%). The Alpine musk deer and Alashan red deer shared nine species of food plants in total, and the index of niche overlap was 83.75%. The Shannon-Wiener index, Pielou uniformity index, food niche breadth index, and largest species diversity index were higher in Alpine musk deer than in Alashan red deer. |
