獐是国家二级重点保护动物，曾广泛分布于鄱阳湖区，但是过度捕猎和栖息地丧失造成种群数量急剧下降，鄱阳湖区獐的数量仅剩1000只左右。近年来，鄱阳湖洪水期水位上升明显，枯水期水位持续偏低，湿地景观变化剧烈。獐如何适应鄱阳湖区环境的剧烈变化，规划中的鄱阳湖水利枢纽工程水位控制会对獐的生存产生怎样的影响？针对这些问题，本研究试图使用粪便显微组织分析法和营养成分分析技术，分析獐在不同季节的食物组成、食性选择及食性选择机制，并使用红外自动相机拍摄其觅食节律，以揭示不同水位条件下獐的觅食对策；从景观、区域和微生境尺度分析獐生境利用和生境选择的特点，揭示不同水位条件下影响獐生境选择的关键因子；进而，根据鄱阳湖水位时空变化规律，在GIS支持下拟合水位变化和洲滩淹露的关系，分析不同水位条件下獐生境和食物资源可获得性的变化，评估鄱阳湖水利枢纽工程对獐的潜在影响，为该种群的就地保护和生境管理提供科学的依据。

as a species of the second class of state key protected wildlife, Chinese water deer has been widely distributed in the Poyang Lake. However, excessive hunting and habitat loss have resulted in a drastic decrease of this population. In recent years, the wetland landscape in Poyang Lake has changed intensively because the water deer was higher in summer and autumn and lower in winter and spring than before. How does the population of Chinese water deer in Poyang Lake adapt well to its habitat with notable change of water level? Which effect may be exerted on this population by the proposed dam construction across the northern end of Poyang Lake? starting from this problems, we proposed to discover its diet and food selection mechanism, and its foraging strategies under the condition of different water level, using microhistological analysis technology of feces and technology for determining plant nutrinent contents, energy and scondary compounds. Also, we propose to use infared automatic camera to record its foraging behavior. using 3S techonology, we porpose to study its habitat characteristic and habitat selection on the scale of landscape, range and mircohabitats, to find the key factors determining its habitat use. By simulating the correlation between water level and the sunmersion-emersion dynamics of grassland according to historical hydrologic data and remote sensing data, we plan to analysis the availability and distribution change of habitat and food resource for Chinese water deer when Poyang Lake is in different water level. Then, we can assess the potential impact of water control after the proposed dam constructed on the survival of Chinese water deer. We hope our research achivement will supply a good scientific data for the decision making on the conservation of the population and habitat of Chinese water deer.
