A Study of Low-carbon Economy Eco-agriculture Model and Countermeasures in Case of Three Gorges Reservoir

The main reason of global climate warming is that the concentration of carbon rapid rise in atmosphere. In response to global warming, the characteristics of the new development model is low-carbon，as a fundamental way to reduction the greenhouse gas emissions and combat global warming. Agricultural ecosystem as the largest artificial ecosystems is an important source of carbon emission. Agricultural activity closely related to climate change, agro-ecological systems have become the second largest sources of greenhouse gases. In this paper, as the Three Gorges Reservoir area for example, based on analysis the problems of agricultural development in the reservoir area, discuss the significance of develop low-carbon cycle ecological agriculture of the reservoir, proposed the general pattern of development low-carbon cycle ecological agriculture and five measures to reduce carbon emissions of agricultural production. The five measures are popularize No-till, flood drought rotation and moderate drainage of paddy fields, development the new energy system at the core of biogas in rural areas, development high efficient ecological cycle of agricultural planting, cultivating new farmers.
