| titleOfInvention | Analysis method and system of nitrogen and phosphorus pollutants in watershed based on multi-isotope combined tracer |
| abstract | The invention discloses a watershed nitrogen and phosphorus pollutant analysis method and system based on multi-isotope joint tracing. The method includes: combining environmental radionuclide tracing and single compound stable carbon isotope tracing to identify the contribution of soil surface and subsurface layers and different land use types to sediment deposits in the watershed, and utilize nitrogen, oxygen, phosphorus and Oxygen isotope tracing to identify the source of nitrogen and phosphorus pollutants in water. The present invention can realize accurate source identification and quantitative analysis of pollution degree of two phases of water and sediment in nitrogen and phosphorus pollutants in the river basin through the method of multi-isotope combined tracing. |
