198 3年至 1 999年对浙江省鹭类营巢地进行了调查。发现鹭类营巢地 2 2处 ,其中浙江北部地区有 1 5处 ,占 68 1 8% ,浙江中部地区 6处 ,占 2 7 2 7% ,海岛 1处 ,占 4 55%。现存营巢地 1 2处 ,其中浙江北部地区 8处 ,占 66 67% ,浙江中部地区 3处 ,占 2 5 0 % ,舟山海岛 1处 ,占 8 33% ;废弃营巢地 1 0处。鹭类营巢地居住年限在 1～ 1 6a ,居住 5a以下的占 72 72 % ,6a以上较少。鹭类营巢地废弃的主要原因是生境破坏、人为干扰和农药污染。鹭鸟群栖对林木生长也会产生一定影响。图 2参 1
Twenty two heronries were found in Zhejiang Province from 1983 to 1999.Among them,15 heronries were in northern Zhejiang,6 heronries in the middle of Zhejiang,and 1 heronry in an island.There are only 12 heronries in existence,which are located in different parts of Zhejiang Province(8 heronries in northern Zhejiang,3 in the middle and 1 in Zhoushan Islands).The inhabited life of heronries varies from 1 to 16 years,and 72 72% of them is less than 5 years.Destruction of habitants,human disturbance and environment pollution are main factors of unsteady heronries.Heron activities bring about some effects on the growth of trees.
