The ecological restoration carried by Chinese central government in Yangtze river basin has greatly changed interactions between natural system and agricultural system through the variation of land cover and land use. However, with the rapid development of urbanization and economy, the competitive demand for land use among nature, agriculture, and human habitation will become fiercer. How to make a balance between these three system is a new challenge for China’ future. The project aims to identify the impacts of re-greening effects on the natural system and agricultural system in Yangtze river basin and provide insights for developing a new pattern of agricultural green development. The project would be divided into four parts: 1) identify the impacts of water yield and flood frequency on agricultural development in upper Yangtze; 2) study the carbon cycle regarding land use change and agricultural development in upper Yangtze; 3) analyse the interactions between ecological restoration in upper Yangtze and the agricultural development in middle and lower Yangtze; 4) make scenario analysis for sustainable future patterns of agricultural green development.
