利用2011年鄱阳湖监测点全年的水环境参数数据，基于相关系数法，对鄱阳湖污染物时空相关性及时空变化规律进行了研究。结果表明，鄱阳湖水质存在时空相关性，枯水期空间分异性较大，1月份TR值最大，这与鄱阳湖水位变化相关；鄱阳湖南北湖区空间分异性从主湖区都昌处沿远离都昌方向分别向北部、南部地区随着距离的增大而逐渐减少，其中监测点L7的PR值最小，这主要受到周溪地区珍珠蚌类水产养殖的影响。

Utilized the all-year's water environment monitoring data of Poyang Lake in 2011,based on the correlation coefficient method,the spatio temporal correlation of pollutants in Poyang Lake and the law of the temporal spatial variation were studied. The results showed that there existed certain spatio-temporal correlativity of water quality index in Poyang Lake,the spatial distri-bution of these indexes in wet season were more obvious than that in dry and flat season with the TR of 0.7108 ,which was related to the variation of the water level. Besides,the spatial distribution is decreased with the increase of distance along the direction from north lake to south lake,in which Site L7's PR showed the lowest value (0.7169),and breeding pearls around Zhouxi area should be a key factors to influence the water quality.
