| 摘 要： | 时空相关性分析方法在生态环境空间分异笥以及湖泊湿地自然保护区建设等方面的研究上，具有重要的应用价值。将湖泊水质监测数据与空间数据结合，建立了具有时空特征的洪渗湖水质数据库。基于相关系数矩阵，利用GIS和Origin等分析软件，对洪泽湖水质的时空相关性及其时间和空间分布规律进行了研究。结果表明，洪泽湖水质存在着时空相关性，目前这种时空相关性已受到人类活动的强烈干扰，因此，建议洪泽湖湿地自然保护区应该选择在时空间相关性小，具有一定离群性的“岛屿”区域。 |

| Abstract: | Hongze Lake is one of the five biggest frestwaterr lakes of China. Based on the monitoring environmental data in 1990-2000 in Hongze Lake, a database of lake water quality and spatial distribution was established. After analyzing the correlation matrixes of water quality indexes and sampling points, the spatio temporal correlativity of water quality indexes were revealed by using the software of Origin and GIS etc. The temporal and spatial distribution characters of water quality indexes in Hongze Lake were also given. The result showed that there existed certain spatio temporal correlativity of water quality indexes in Hongze Lake; and the spatio temporal relativity of water quality indexes had been strongly disturbed by human activities. Hence the nature reserves in wetlands should be located in the areas with low spatio temporal correlativity. |
| Keywords: | Hongze Lake water quality spatio temporal correlativity |
