| 摘 要： | 以浑河流域上游地区为研究流域,应用SWAT模型估算了该流域硝态氮淋失量的空间和时间分布以及不同土地利用类型硝态氮的淋失量。利用2008—2010年实测径流资料对模型进行了校核与验证,结果表明,流域硝态氮的淋失量与施氮量在空间分布上是一致的,且与水分渗漏有较好的相关关系,降雨、施肥是影响流域硝态氮淋失的主要因素;此外,不同土地利用类型的硝态氮淋失量的差异也非常明显,耕地的硝态氮淋失量最高,林地次子,居民区、裸地等最小。 |

| Abstract: | We employed the Soil and Water Assessment Tool(SWAT) to investigate the temporal and spatial variability of nitrate leaching in upper area of Hunhe basin,and analyzed nitrate leaching in different land use scenarios.Model calibration and validation results,based on river discharge data for the outlet of watershed from 2008 to 2010,are quite satisfactory.The results showed that the spatial distribution of nitrate leaching was accordance with that of N application.And nitrate leaching was closely related to water percolation.In addition,nitrate leaching was distinct between land use scenarios,found to be highest in Agricultural land,second in forest land and lowest in resident area,bare land,etc. |
