Abstract The regional ecological issues, which are triggered by the global economic integration, regional development integration and ecological service transfer,have been attracting more and more people’s attention, and have a direct impact on regional sustainable development. Developing a systematic subject on handling regional ecological issues becomes urgent. In this paper, we try to set up the theoretical framework of regional ecology in aspect of subject development based on ecology, geology, economy and other relevant subjects. Ecology is the subject which studies regional ecological structure, process, function as well as the integration and interaction mechanism of regional ecological elements; ecological medium is the link and key element between the ecological regions. According to the components of the ecosystems and current human activities, the most important ecological medium affecting the region include wind, water and resource, which form three kinds of ecological regions-basin, wind field and resource cycle respectively. The main study area and key issues of regional ecology include regional ecological structure, process, function; regional ecological integrity and differentiation rules; regional ecological evolvement rules and driving forces; regional ecological carrying capacity and suitability; regional ecological link and ecological assets transfer; regional eco-compensation and environmental profits sharing mechanism.
