摘 要 ：本文报道池鹭种群数量变动、种群活动、雏鸟生长和生物生产量。种群活动可划分为迁到期、动情期、繁殖期、同巢鸟活动期、集群活动和迁离期。１９９０、１９９１二年繁殖前种群密度分别为１３００只／ｈｍ￣２和１４０１只／ｈｍ￣２，繁殖后增加密度为２０８７只／ｈｍ￣２和２２４８只／ｈｍ￣２。雏鸟体重增长曲线方程为：Ｗ＝２８６／ｌ＋ｅ￣（－０．０４０９（ｔ－１２．６））１９９０、１９９１年繁殖种群的生物生产量分别为１９７．２８９１４ｋｇ／ｈｍ￣２和２２３．１８７１２ｋｇ／ｈｍ￣２。

Abstract:This paper reports the population dynamics,activities and biomass production of breed-ing population of chinese pond heron from April to September in both 1990 and 1991 at theDongbaowu forest farm in Zhejiang province,China. The population activitles of chinese pondheron may involve 5 phases:homing phase,oestrus phase ,propagation phase,clutch activityphase,schooling and emigration phase. The breeding density of chinese pond heron was 1300ind./hm￣2(1990)or 1401 ind./hm￣2(1991 ) before breeding,and increased ...
