摘要：
We studied the total nitrogen (TN) concentration, the total phosphorus (TP) concentration, and the TN/TP ratios in 12 reservoirs located in the southern Iberian Peninsula, to study the influence of land-use in the reservoir watershed on the trophic status of these systems. The TN/TP ratios indicated limitation by P or co-limitation depending on the system. Only the percentage of agriculture areas significantly classified the reservoirs by their P and N concentrations, while the percentage of urban areas also grouped the reservoirs by their N contents, according to the univariate tree regression analyses. We found a positive relationship between the percentage of agriculture areas and the trophic state of the reservoirs, according to the Carlson index (TSI), that indicates a deterioration in water quality in the reservoirs induced by agricultural activity.
