大丰麋鹿保护现状与可持续发展策略探讨

Conservation Status and Sustainable Development Strategy of Milu(Elaphurus davidianus) in Dafeng

江苏大丰麋鹿为重引进物种,大多散养在人工圈围的封闭围网内。由于该种群密度过大而导致的生境恶化、食源短缺、发生传染性疾病风险增加等制约着其可持续发展。介绍了江苏大丰麋鹿国家级自然保护区现状,分析了制约大丰麋鹿种群可持续发展的主要因素。建议实施扩大栖息地、麋鹿生境恢复与改造、人工补饲、异地建立种群、血统交换、培育圈养商业用品系、积极预防传染病等人为干预措施,以丰富麋鹿种质资源遗传多样性。

Milu( Elaphurus davidianus ) in Dafeng of Jiangsu is a re-introduced species,which is mostly scatter-fed in the enclosure of artificial ring. Because the population density is too large, habitat deterioration, shortage of food sources, increased risk of infectious diseases and other factors restricted its sustainable development. The current status of national nature reserve of Milu in Dafeng of Jiangsu was introduced,and the main factors that restricted the sustainable development of Milu population were analyzed. Artificial intervention measures were suggested,including implementation of expanding the habitat,habitat’s restoration and transformation of Milu,artificial supplemental feeding,the establishment of different population, exchange of bloodline, breeding circle and nutrient line and active prevention of infectious disease, etc ., so to enrich the genetic diversity of Milu germplasm resources.
