Study on the Linkage Between Urban Built-Up Land and Water Quality in the Jiulong River Watershed
九龙江流域城镇建设用地与河流水质关系研究

Band grouping indices combined with single band characteristic were used to extract urban built-up land based on satellite image in the Jiulong River Watershed.Landscape ecology method and statistical analysis were employed to explore the relationship between urban built-up land and permanganate index,NH+4-N,TP concentrations.There were significantly positive correlations between the proportion of urban built-up land and permanganate index,NH+4-N,TP(r= 0.701,0.695,0.789).It indicates the proportion of urban...
