Since the beginning of winter in 1998, nine surveys of the waterfowl of Anatidae in the Poyang Lake region have been conducted, using the synchronous counting investigation.

为掌握鄱阳湖区域雁鸭类水鸟资源状况，从1998年冬季开始，采用同步调查计数法在鄱阳湖区域进行了9次雁鸭类水鸟调查。

The investigation results showed that there were 26 species of the waterfowl of Anatidae, belonging to 7 orders, of which 1 species belong to gradeⅠ key state-protected species and 3 species (Cygnus columbianus, Anser albifrons and Branta ruficollis) belong to gradeⅡ key state-protected species.

结果表明：共调查记录到雁鸭类7属26种，其中国家重点保护动物4种，包括国家Ⅰ级重点保护动物1种［中华秋沙鸭］和国家Ⅱ级重点保护动物3种［小天鹅(Cygnus columbia-nus)、白额雁和红胸黑雁］。

And most of the endogenous rivers, the seasonal river ducks River was also evident, Jiaying winter blight and October each year down to the following year in May, the low-water ducks, some sections of riverbed revealed, forming numerous shoals, shallow water, deep water, the duck turned into a big river wetlands in river system, but also a large number of wild ducks therefore category Charadriiformes placing of wintering waterfowl and birds of prey, and the movement of supplies to.

和大多数上源性河流一样，鸭子河河水的季节性也很明显，夏盈冬枯，每年十月以降，至次年五月，鸭子河水位低落，部分河段河床显露，形成无数滩涂、浅水、深水区域，整个鸭子河变成一大的河流湿地系统，也因此成为大量雁鸭类鸻鹬类水鸟及猛禽的越冬地及迁徙补给地。

Patuxent's scientists have been responsible for many important advances in natural resource conservation, especially in such areas as migratory birds, wildlife population analysis, waterfowl harvest, habitat management, wetlands, coastal zone and flood plain management, contaminants, endangered species, urban wildlife, ecosystem management, and management of national parks and national wildlife refuges.

其研究涉及自然资源保护的许多学科，尤其是候鸟、野生动植物数量分析、水禽、生境管理、湿地、海滨区和雨林区管理、污染物、濒危物种、城市野生动物、生态系统管理、国家公园和自然保护区管理。

Through field observations and sampling, by referencing to other documents and information, with correlation analysis and principal component analysis as mathematical tools, we know that: the distribution of the number of birds has close relations with density of zoobenthos and ratio of water area, the correlation coefficient of the distribution and the two factors are 0.916 and 0.745, the density of zoobenthos is the most direct reflection; Vegetation types , the coverage and water level may have relations with the distribution of the kind of birds, normally, middle and large volume birds need high vegetation and high coverage as their habitats, and waterfowl like deep water as their habitats; Human activities have low impact on the the distribution of the number of birds, but the activities have relations with all the other environmental factors.

通过实地的观测、采样，并结合其他文献的资料，以相关分析和主成分分析作为数学工具，得知：鸟类的数量分布和底栖生物密度、水域面积比例有着密切关系，鸟类数量分布与两者的相关系数分别为0.916和0.745，其中，底栖生物密度是鸟类数量分布的最直接反映；植被类型、植被盖度和水位可能与鸟类的种类分布有一定关系，通常体积中、大型的鸟类需要较高的植被高度，来作为自己的栖息场所，水禽需要水位较深的区域作为自己的栖息场所；人为活动对鸟类数量分布的影响不大，但对所有自然环境因子都有一定影响。
