| Zusammenfassung |
| The identification of priority management areas (PMAs) is
essential for the control of non-point-source (NPS) pollution, especially
for a large-scale watershed. However, previous studies have typically
focused on small-scale catchments adjacent to specific assessment points;
thus, the interactions between multiple river points remain poorly
understood. In this study, a multiple-assessment-point PMA (MAP-PMA)
framework was proposed by integrating the upstream sources and the
downstream transport aspects of NPS pollution. Daning River watershed was
taken as a case study in this paper, which has demonstrated that the
integration of the upstream input changes was vital for the final PMAs map,
especially for downstream areas. Contrary to conventional wisdom, this
research recommended that the NPS pollutants could be best controlled among
the upstream high-level PMAs when protecting the water quality of the entire
watershed. The MAP-PMA framework provided a more cost-effective tool for the
establishment of conservation practices, especially for a large-scale
watershed. |
