Landscape metrics as indicators of river water quality at catchment scale

摘要: We investigated the relationship between land use parameters and FRAGSTATS-based landscape metrics (Edge Density, Patch Mean Shape Index, Euclidean Nearest Neighbour Contagion, Richness Density Shannon's Diversity Index) nutrient/organic-matter-based water quality indicators (BOD7 CODKMnO4 values, total-N total-P concentrations in water) 24 catchments with various patterns Estonia, using CORINE Land Cover Map (1:100 000). Multiple regression analysis showed that, for BOD7, total-P, most important predictor was proportion of urban areas, but also had a significant quality. Index Contagion were predictors CODKMnO4. The knowledge that configuration impact can be used establishing implementing management plans Europe. Keywords Catchments; use; metrics;
