Popis: 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.
