摘　　要：2018年对向海湿地水鸟迁徙情况进行了调查分析,结果表明:向海湿地的水鸟主要集中在春季3月中旬—4月中旬进入迁徙高峰,4月中旬水鸟数量达到最高。大量的旅鸟停歇一段时间之后过境,4月下旬开始下降,说明水鸟种群在继续向北迁徙至繁殖地。进入5月后,在向海保护区境内停留的鸟类进入繁殖季节和育雏期,水鸟总体数量趋于平稳,此时种群结构稳定。在秋季的候鸟迁徙期,迁徙高峰主要出现在10月上旬—11月上旬,进入11月中旬,随着气温降低,水鸟种类和数量骤降。The migration of waterbirds to Xianghai wetland in 2018 was studied,the result showed that:The main migration peak of waterbirds to the Xianghai wetland is from mid-march to mid-April in spring,and mid-April reached the highest.Large Numbers of migratory birds pass through after resting for some time and then the number of waterbirds begin to decline in late April indicating that the population continues to migrate north to its breeding grounds.The passing bird left entering the May and some birds began to breed,the number of waterbirds is steady.Migration peak is from early October to early November in autumn,as the temperature decreases entering the middle of November and the species and number of waterbirds drop sharply.
