提出了一种面向行政区总氮污染源解析的流域模型技术方法，基于广义流域负荷模型（GWLF），结合净氮负荷输入系统（NANI），利用地理信息系统（GIS）空间分析技术，衔接子流域分区和行政区管理边界，实现面向人为定义空间区域模拟的流域模型应用，并在中国安徽省黄山市新安江流域针对重点区县开展了案例研究。结果表明：休宁县、屯溪区、歙县对街口国控断面总氮污染物的比例分别为15．5％、41．4％、43．1％；不同区县内对流域出口的总氮污染物所占比例呈现行政区域特征。本研究方法能够实现对新安江流域总氮污染负荷来源的行政区差异性解析，进而针对不同区县污染特征开展有针对性的污染治理措施，为水环境分区化管理提供有效的决策支持信息。

The paper introduced a method of basin model about total nitrogen source apportionment faced on administration.Based on generalized watershed loaded function (GWLF), combined with net anthropo-genic nitrogen inputs(NANI) and geographic information system (GIS), it implemented user -defined area( administrative ) simulation through linking up the watershed boundary partition and administrative region.This method has a good application in Xin'anjiang basin .The results show that Xiuning County , Tunxi District, She County account for 15.5%∶41.4%∶43.1%in total nitrogen pollution to the Jiek-ou state-controlled section .The different districts show administrative regional characteristics .The method can achieve analyzing different administrative regions'total nitrogen source apportmention and providing effective decision-supported information for the watershed partition management of water environment .
