摘　　要：在2002～2004年的 6～7月,每天观察扬子鳄的营巢行为,记录天气状况,得出扬子鳄的营巢时间受天气的影响,巢材湿度会影响鳄的产卵时间;在6月下旬末大雨天后,连续2～3天气温能保持在26～35℃时,鳄就会产卵;在整个产卵期巢受到严重破坏时,鳄不会产卵.During June and July from 2002 to 2004, the weather condition and the nesting action of the Chinese Alligator was observed. The results showed that weather condition affected the nesting time and the moisture of nest material affected the time of laying eggs. When the air temperature maintained 26-35℃ for 2 or 3 days after heavy rainy day in the last ten days of June, the female alligator could lay eggs. If the nest was heavily damaged in a whole period of laying eggs, female alligator could not lay eggs at this nest.
