摘　　要：探讨了年龄、体质指数对人体粪尿氮排泄量的影响。结果表明:人体尿氮和粪氮排泄量分别为9.16和1.33g/(cap.d)。粪、尿氮排泄量随着年龄增长呈递增趋势,但因机体体质的差别表现出一定的差异。总体上,体质指数高者其尿氮也明显增多,而粪氮则没有明显变化。在此基础上,综合考虑这2个因素及其交互作用的影响,建立了一种粪尿氮排放模型,以期为人体粪尿氮排放的估算和治理提供依据。The effect of age and BMI on nitrogen excretion of human excreta was investigated. The results showed that ： the excretion of urine nitrogen was 9.16 g/（cap · d） , and the excretion of fecal nitrogen was 1.33 g/（ cap · d ）. With aging, the nitrogen excretion of human excreta showed an increasing tendency, but some differences were present because of the difference in physical condition. When BMI gone up, it also led to the increase on urine nitrogen, hut there were no significant changes in different BMI groups. On this basis, the model of nitrogen emission of human excreta was established, which gave a comprehensive consideration of age, BMI and their interaction effect. It has important guiding significance for estimating and fathering of the human excreta.
