【摘要】 对长江口南岸春季鸻鹬类在迁徙期间,设置六条样带,进行种类和数量统计,并经多样性指数的测算。其结果表明:鸻鹬类的数量存在由南向北呈梯度递减变化。由此推测鸻鹬类在长江口的迁飞方向:在飞越杭州湾后,大部分从南汇角至朝阳农场飞抵崇明东滩暂作逗留,补充能量,然后继续北飞。更多还原

【Abstract】 The study was carried out in the southern coastline of Yangtze river estuary in April 1997. The six sample zone was set up along the coastline. Walking and observation is the main method for shorebird number counting, and give test of diversity index. The results show that there is a gradient (from south to north) in the number of shorebirds. Thus, the above mentioned fact proved that most of shorebirds from Nan - Hui - jiao after flying over Hang - zhou Bay to Chao - yang Farm turned to the Estern Beach of Chong - ming Island, and then the countinuing northward.更多还原
