洪湖越冬水禽的研究

STUDIES ON OVERWINTERING WATER BIRD IN HONGHU LAKELAND

依据１９９６年８月至１９９７年５月对洪湖越冬水禽的调查及有关资料，分析了在湖区越冬水禽历年来种群数量的递减及丰富物种向小型化、单一化演变的趋势及原因；提出了相应的措施．

Based on the materials of 1960s and 1980s and on this imestigation the author indicated the reason of the decrease of the birds species population which overwintered in Honghu lakeland and discussed the tendency that abundant species have developed to small group. At last, the author put forword some appropriate tactic for these reason.
