Abstract

Abstract: Nutrition level can quantify the complex human dietary structure and study the material circulation and energy flow in human ecosystem. Based on the data of food consumption of urban and rural residents in Zunyi City, Guizhou Province from 2001 to 2016, the nutritional grade of urban and rural residents was analyzed. The results showed that the nutritional level of urban residents increased from 2.18 to 2.29, and that of rural residents increased from 2.07 to 2.16. Vegetables contributed the most to urban nutritional level（28.2%） and food contributed 42.46% to rural residents. The average contribution rate of animal food to urban residents' nutritional level was higher than that to rural residents' nutritional level. The level of nutrition increased first and then decreased, and the level of nutrition of rural residents showed two growth rates. From this point of view, the impact of market price, zoonosis and health knowledge on the nutrition of urban and rural residents is different. Urban residents' nutritional level is more affected by zoonosis, while rural residents' nutritional level is more affected by market price fluctuations.

Key words: trophic level, contribution, dietary pattern, Zunyi city
