摘　　要：运用N-Calculator模型,在1995-2016年乌鲁木齐市城镇居民各类食物消费统计量的基础上估算乌鲁木齐市城镇居民氮足迹,并分析其氮足迹的动态变化特征和影响因素.结果表明:(1)1995-2016年,乌鲁木齐市区域总氮足迹和人均氮足迹均增长,其中,人均食物氮足迹占比大,能源氮足迹占比小但增长最快;(2)城镇人均食物生产氮足迹在人均食物氮足迹中占主导地位,畜肉类、粮食、蔬菜、水产品、蛋类和水果类生产氮足迹影响着食物氮足迹;(3)柴油和汽油对乌鲁木齐市人均能源氮足迹贡献最大,交通是能源氮足迹的主要影响因素;(4)乌鲁木齐市氮足迹低于经济发达地区.This study used the N-Calculator model to estimate the nitrogen footprint of urban residents in Urumqi on the basis of various food consumption statistics of urban residents in Urumqi from 1995 to 2016,then analyzed the dynamic characteristics and influencing factors of nitrogen footprint.The results showed that:(1)From 1995 to 2016,both the regional total nitrogen footprint and per capita nitrogen footprint of Urumqi City increased.Among them,per capita food nitrogen footprint accounted for a large proportion,energy nitrogen footprint accounted for a small proportion but the fastest growth;(2)Urban per capita food production nitrogen footprint is dominant in the per capita food nitrogen footprint.The nitrogen footprint of livestock meat,grain,vegetables,aquatic products,eggs and fruits production affects the food nitrogen footprint;(3)Diesel and gasoline contribute the most to the per capita energy nitrogen footprint of Urumqi,and transportation is the main influencing factor of energy nitrogen footprint;(4)Urumqi’s nitrogen footprint is lower than that of economically developed regions.
