A framework for assessing the effects of afforestation and South-to-North Water Transfer on nitrogen and phosphorus uptake by plants in a critical riparian zone

摘要: The uptake of nitrogen (N) and phosphorus (P) by plants in riparian zones can significantly decrease the water pollution risk. Moreover, vegetation area zone be impacted raising level afforestation. As largest reservoir North China, Miyun Reservoir is affected South-to-North Water Transfer (SNWT) large-scale However, few efficient technology frameworks that used to assess effects similar anthropogenic projections on N P at catchment scale have been reported. Therefore, this study proposed a framework including an ecological simulation tool coupled with multi-source data scenario setting methods identify these two projects from April September 2015. results show total are 1214.18 t 148.66 t growing seasons. After afforestation, removal will increase 2.56 (2.17) times (below 160 m elevation). When rises 150 m elevation, joint afforestation SNWT removals 851.18 t 83.33 t. This implies offset negative effect caused SNWT. Overall, provide useful scientific reference for design effective management zone.
