Abstract:A questionnaire of "How the daily travels of urban families affect the nitrogen emission in 2015" was carried out in Hangzhou, including factors related to family members' age, income, education, occupation, type of family households and family cars ownership. Methods of correlation analysis and optimal scaling regression analysis were used in this study. The results obtained are as follows:(1) all the attributes of the family members have impact on the amount of nitrogen emission in daily travel, e.g.,families with both members aged between 31-50 incur the largest amount compared with other ages, and when the family income was in 15 001-20 000 yuan or above, the amount increased dramatically, the education level of the second member affects the amount more than that of the first member, and the amount of nitrogen emission also depends significantly on the occupations of both members, Furthermore, the total amount of nitrogen emission of urban households accounts for 2.6 times compared with rural households, and that of families with cars accounts for 16 times than otherwise; (2) influence factors in a descending order are as follows:family cars ownership, transportation manner, educational level of the second member, occupation and family members' age, respectively. This study could provide a useful reference for the construction of urban with low nitrogen emission.
