大丰麋鹿主要生活区的生境特征调查

Habitat Investigation of the Main Living Area of Dafeng Milu

麋鹿重引进是中英两国政府合作的一项伟大工程,大丰麋鹿自回归以来,逐步克服了水土不服、难产率高等难题,种群数量已由39头增至2 818头。随着麋鹿种群的发展,大丰麋鹿主要生活区内的生境特征也发生了巨大变化,植被在不断退化,甚至出现了某些植物在区域内消失等反常现象。大丰麋鹿种群的增长与生活区主要采食植物狼尾草(Pennisetum alopecuroides(L.)Spreng)的长势呈负相关状态。因此,生境退化及麋鹿种群未来的发展问题是一个发人深省的难题,必须尽快将麋鹿种群发展的未来导向提升到日程上来。

The Milu Reintroduction is a great project by cooperating of Chinese and British governments. The population of Milu has been developed from 39 to 2 818 since Milu were returned to Dafeng and overcome the problems of non-acclimatization and high rate of dystocia gradually. With the development of the Milu population, the characteristics of mainly habitat had been greatly changed. Vegetation degenerated, some plants even disappeared in certain areas. It was found that the growth of the Dafeng Milu population and Pennisetum alopecuroides（ L. ） growth in the mainly living area are of negative correlation. Therefore, habitat degradation and development of the Milu population in the future are thought-provoking problems. We must take action to solve the problem of the Milu population development in the future as soon as possible.
