[Method] Taking the economically coordinated region of Wuling Mountain as an object, two economic development ways existing in the region, namely the traditional and low-carbon economic development mode, were compared from development prospects, policy support and so forth. [Result] Given the development prospects and policy support, it is necessary to choose low-carbon development mode in an area with good ecological environment. Moreover, developing clean energy industry and tourism industry, and changing traditional ideas are the main measures to develop low-carbon economy. [Conclusion] The research could provide references for the selection of economic development mode for an area with good ecological environment.展开更多
