The richness and stable condition of migrants, the construction of ecological environment and the harmonious development of socio-economy in Three Gorges is an important problem in post Three Gorges. It's regretful that there are some contradictions exist in the man-land relations, employment and ecological problems in the reservoir area now, which leads to the necessity to protect the ecological environment following a low-carbon development. Firstly, we suggest develop low-carbon tourism industry which means to plan the tourism resources effectively, cultivate low-carbon tourism industry groups, create low-carbon transport corridors, and market special products in the reservoir area. Secondly, we suggest develop low-carbon farm aptly and set up a domestic carbon trading market. Finally, it's necessary to build a low carbon living system in the reservoir area, and make the Three Gorges area to an exemplary low-carbon area in China.
