摘　　要：鄱阳湖临湖区是鄱阳湖湖体与五河流域的衔接带,但没有明确的边界范围。为此,从生态环境科考的角度出发,界定了鄱阳湖临湖区内涵及范围;并采用GIS空间分析方法和野外考察相结合,划定了临湖区的界线。临湖区有入湖口18个,涉及南昌市、九江市、上饶市、宜春市和景德镇市,总面积2.34万km2。临湖区范围的确定,为地表水过程、泥沙过程的研究提供了清晰的边界,并在空间上实现了自然过程和人文过程的衔接。Poyang Lake Adjacent Region（ PLAR） is the interface between Poyang Lake and the five rivers in Poyang Lake basin,but its boundary remains unclear. From the perspective of ecological scientific expedition,the meaning and the scope of PLAR is defined and based on the basic geographic information and hydrological data,the boundaries are delimited by the method of GIS spatial analysis. The result show that there are 18 main lake entrances in the PLAR,involving Nanchang,Jiujiang,Shangrao,Yichun and Jingdezhen,with a total area of 2. 34 × 104 km2. The delimitation of PLAR provides a clear boundary to the research on hydrological process,such as the surface runoff and sediment movement processes,and realizes a link-up between natural process and humanistic process.
