摘要
1985—1986年在北京麋鹿苑,1987—1990年在江苏大丰麋鹿保护区研究了半散放糜鹿Elaphurus davidianus生境植被,系统记录了糜鹿采食植物共263种,隶属于49科164属。其中,北京麋鹿苑采食植物39科86属118种;大丰糜鹿保护区采食植物42科133属194种及变种。植被及采食种类情况表明,两地麋鹿饲料植物多样性较好,鹿群规模在迅速增长。但几年来,两地生境植被不同程度恶化显著,主要因放养范围小、鹿群规模相应过大。而植物区系组成简单、群落发育年轻、植被演替迅速也是植被恶化原因。扩大放养范围、改善栖息条件已属迫切任务。
The research was carried out at Beijing Milu Reserve in 1985-1986 and at Da Feng Milu Reserve from April 1987 to March 1990.For the first time 263 plant species eaten by Milu are recorded. The plant species belong to 49 families and 164 genera with 39 families 86 genera 118 species at Beijing Milu Reserve and 42 families 133 genera 194 species at Da Feng Milu Reserve. Fifty one plant species eaten by Milu are the same at the two Reserves. It was suggested that the vegetations could satisfy Milu's needs of living and reproduction and the mean annual increasing rate at the two sites were more than 20% in the last years.
Monthly number of plant species eaten by Da Feng Milu herd and ground vegetation biomass (Data from 30 samples taken monthly) are shown in figure 2 and figure 1 respectively. Habitat vegetations have deteriorated in the two sites because of heavy grazing and Milu's Underfoot trample as well as simple flora, young development of plant comunity and rapid succession of vegetation. It would be a good way if one third of Milu in the two sites were removed to new suitable habitats.
