The results
showed that water quality was highly dependent on the spatial distribution of POI types. The water quality was
good in central ancient city zone but was poor in the north and south. Pearson correlation coefficient between POI
multi type kernel density index with buffer radius of 50 m, 100 m, 150 m, 200 m, 250 m, 300 m and water
quality comprehensive index were 0. 559, 0. 607, 0. 573 , 0. 521, , 0. 422, respectively. The correlation
was significant when the buffer radius was 100 m.
