舟山群岛獐的食性研究

利用野外观察、粪便显微组织学分析和投喂实验等方法对舟山群岛獐的食性进行了研究。结果表明，研究地的獐所食植物共有137种，隶属于61科115属，其中豆科植物在取食种类和取食频次上均多于其它科植物。尽管獐对植物科和种的选择在四季间没有显差别，但取食科和种的数量依然从春天到冬天呈递减趋势，并且冬天与其它3个季节差别较大。獐的食物中，每个季节都含有非禾草类草本植物、禾草类草本植物、木本植物和蕨类植物，且其食物组成在季节间亦无显差异；除木本植物外，獐对其它3类植物的选择在季节间有显差异。獐在冬天较多选择木本植物，而其它季节较多选择草本植物，但木本植物和非禾草类草本植物在四季食物组成中均占较高比例，而禾草类植物所占的比例很小。因此，笔认为舟山群岛的獐应该偏向于嫩食。

Diet of the Chinese Water Deer (Hydropotes inermis)in Zhoushan Archipelago, China

This study was to determine what kind of feeders the Chinese water deer are in Zhoushan Archipelago, China. The study was conducted by using observation of feeding signs in the wild, microhistological analysis of feces,and feeding trials. The results showed that Chinese water deer fed on a total of 137 plant species, included in 61 families and 115 genera. Leguminosae plants were selected most,both in numbers of species and frequency of occurrences. Even though they maintained a relatively constant usage level of plant species and families, the numbers of both decreased from spring to winter, but diet in summer and autumn were similar to that in spring. All of the four plant types (forbs, graminoids, woody plants and forbs) were taken year-round with no significant differences, even though they were varied among seasons, however all types except woody plants showed significant variation among seasons. Herbage intake decreased while that of woody plants increased,from spring to winter. Woody plants and forbs were dominant,while graminoids were rare in the diet of the deer. The results suggested that the Chinese water deer is a concentrate feeder or a browser in Zhoushan Archipelago, Zhejiang Province, China.
