2006年12月19日至30日，对江西省三龙镇内的西河段、富良县内的长江段、武源县内的leanjiang段、益阳县内的新疆段、秀水县内的秀水段、永和镇内的赣江段、姚头镇内的赣江段进行了越冬分布和种群规模的调查，共观察到鳞沙鸭82头，其中雄鳞沙鸭31头，雌鳞沙鸭51头雌性或未成熟。益阳和婺源是有记录的越冬地。阜良和秀水率先报道，鳞沙鸭数量分别达到22头和23头。越冬生境特征明显存在共同点。受益范围必须超过这些范围和地点。在江西越冬的秋沙鸭的种群规模肯定远远超过本研究中观察到的数量。江西省被认为是中国秋沙鸭的主要越冬地之一。
From 19 to 30 Dec 2006,Xihe stretch within Sanlong town,Changjiang reaches within Fuliang county,leanjiang reaches within Wuyuan county,Xinjiang stretch within Yiyang county,Xiushui reaches within Xiushui county,Ganjiang reaches within Yonghe town and Ganjiang reaches within Yaotou town have been surveyed to study the wintering distribution and population size of scaly-sided Merganser in Jiangxi Province.82 scaly-sided Mergansers have been observed,31 scaly-sided Mergansers are male,51 are female or immature.Yiyang and Wuyuan are recorded wintering sites.Fuliang and Xiushui are reported firstly,the number of scaly-sided Merganser reached to 22 and 23 respectively.The wintering habitats characters apparently exist common ground.benefiting reaches must exceed these reaches and sites.The population size of the scaly-sided Merganser wintering in Jiangxi Province must far exceed the number that be observed in this study.Jiangxi Province is considered the one of main wintering sites of the scaly-sided Merganser in China.
