摘要
针对迁徙丹顶鹤野生种群数量逐年下降的现状,扎龙保护区利用迁地保护(鹤类驯养繁育中心)在人工辅助繁育丹顶鹤的野化放飞方面做了有益探索,截至2014年底,已累计野化放飞丹顶鹤近200只.半散养丹顶鹤群体较早地占领繁殖地和觅食区,可能会对较晚到达扎龙湿地的野生丹顶鹤种群的栖息和繁殖带来冲击.放飞时间及放飞地点等方面是直接影响丹顶鹤种群放飞野化成功与否的关键.野化放飞位置从单一地点转向多处适宜位置能够避免对野生种群的冲击.放飞时间从每年4月提前至前一年10月,能够增强丹顶鹤野化营巢、自繁及育雏的能力.
In view of the present situation that wild population quantity of migrating wild red-crowned crane is reducing yearly, Zhalong national nature reserve has made beneficial explorations on returning the bred red-crowned crane through artifitcial propagation to wild state by off site conversations （ in the cranes domesticating and breeding centre ）. By the end of 2014, almost 200 red-crowned cranes were returned to wild state. Semi-scatter-fed red- crowned crane population occupies the breeding region and ingestion zone earlier every year, probably which can shock the inhabitation and breeding of those wild one which reaches Zhalong wetland later. The time and place of returning red-crowned crane to wild state etc. can determine if returning red-crowned crane to wild state is successful directly. Change the suitable place of returning red-crowned crane to wild state from single one to multi-one, which can avoid the shock to wild red-crowned crane population. The time of releasing the bred red-crowned crane by artifitcial propagation is advanced from april to last october, which can enhance abilities on building nest, breeding independently and brooding of the bred red-crowned crane by artifitcial propagation after being released.
