Human behavioral impact on nitrogen flow--A case study of the rural areas of the middle and lower reaches of the Changjiang River, China
To assess sustainability of rural management in the Changjiang River basin, human behavioral (food consumption, lifestyle pattern, and human waste disposal) impact on nitrogen flow was quantitatively evaluated. A survey of day-to-day activities was conducted in two representative counties: Taoyuan and Taihe. Daily nitrogen intake from food per capita and potential nitrogen load from human waste on the environment were calculated. The former in Taoyuan and Taihe was 17.0 and 16.0gN, respectively.
