| 摘 要： | 为了研究妫水河流域的氮磷非点源污染来源,在官厅水库周围进行了野外人工降雨实验,结果表明,氮磷输移率与径流量具有很好的相关性,溶解态氮、磷的平均相关系数分别是0.997 8和0.988 9,因此提出了新的溶解态氮磷负荷模型.从妫水河流域的土壤图、土地利用图中提取地理信息,以数字高程模型为依据,应用新模型研究了妫水河流域溶解态氮污染负荷的空间分布。结果表明,溶解态氮主要来自水浇平地,其次是低山和丘陵. |

| Abstract: | In order to research the origin of nonpoint source pollution dissolved nitrogen (DN) and dissolved phosphorus (DP), some artificial rainfall experiments was made at Guanting Reservoir. The experimental data show that the correlation between transporting rate of DN (DP) and the runoff is very good, with the average correlation coefficient 0.9978 and 0.9889 for DN and DP respectively. Therefore, a new load model of DN(DP) is put forward. While applying it, we studied the spatial distribution of DN (DP) pollution load according to the digital elevation model (DEM) and the information obtained from land use map and soil map. Its results show that DN mainly originated from irrigable land first, mound and hill second. |
| Keywords: | nonpoint source pollution DN DP load model geography information system(GIS) Guanting Reservoir Guishui River |
