【摘要】 就地保护的海南坡鹿种群分布于海南大田国家级自然保护区,有野生和半野放两种类型,其中野生种群个体数量为65头,在1986~1992年间年均增长率为2.0%;半野放种群个体数量为1093头,同期年均增长率为22.4%。迁地保护的海南坡鹿的分布种群有野放、半野放和圈养等3种类型,种群个体数量分别为524、337和86头。野放种群个体已有产仔现象;海南邦溪自然保护区的半野放种群在1994~2004年间的年均增长率为18.9%;枫木鹿场的圈养种群同期年均增长率为12.4%。目前,半野放是就地保护的主要方式;而野放是迁地保护的主要方式。应该注重发展迁地保护的半野放种群及其栖息地。对坡鹿的就地保护和迁地保护提出了一些建议。更多还原

【Abstract】 In-situ and ex-situ conservations are the two conservation patterns of Hainan eld’s deer.For in-situ conservation,wild and semi-free populations are two types of Hainan eld’s deer populations which are distributed in Datian Nature Reserve.The population size of the former was 65 individuals and the average annual increase rate was 2.0% from 1986 to 1992.The population size of the latter was 1093 individuals and the average annual increase rate was 22.4%.For ex-situ conservation,the population sizes of escaped,semi-free and captive populations were respectively 524,337 and 86.Reproductions of escaped populations have been observed;the average annual increase rate of semi-free populations was 18.9% from 1994 to 2004 in Bangxi Nature Reserve.The average annual increase rate of captive populations was 12.4% in Fengmu deer farm.Now, the semi-free is a dominant population of in-situ conservation,and the escaped deer is a predominant population in ex-situ conservation.Semi-free populations and their habitats should be enhanced in future ex-situ conservation of eld’s deer.Some suggestions on in-situ and ex-situ conservations are brought up in the article.更多还原
