研究了长株潭城市群绿心的生态、经济和社会意义，借鉴国外经验，提出以生态旅游为核心的保护性开发策略，形成“一心八组团”空间布局。
Green Heart plays a multi-storey role on ecological, economic and sociological significance of the urban agglomeration. Learning the experience of protection on Green Heart overseas, this paper focuses on the geographical characteristics of southern hilly areas to study Green Heart in the crossing borders of Changsha, Zhuzhou and Xiangtan Urban Agglomeration. Faced with the environmental problems of Green Heart, the protective development strategies of Green Heart in the urban agglomeration are put forward through such aspects as environmental protection, optimization of spatial structure layout, intensive use of land, lower energy consumption and pollutants discharge, which aims to develop eco-tourism as the core mechanism for sustainable operation. Thus the space layout model, called One Heart, Eight Clusters, is formed.
