The planning research of the green areas system is based on the careful survey which examines the malpractice of traditional planning. With the direction of scientific theory, assimilation of the achievement on correlative subjects and persevering study of the planning theory and methods at new term. This research establishes the scientific theory for the construction of green area system's planning and city's ecological environment.It explains the basic concepts of ecological resident, ecological cities cityscape and systems of urban green areas at the angle of residential environment and landscape; it also takes apart the relationships between ecological city and ecological resident, the goal and pivotal point of layout of an ecological city and a new developmental strategy of cities in the 21st century; it also generally expatiates on the characters and the contents of city scope planning and city's green area system planning, expatiates on the interactive complementary of the city scope and ecology green area system, expatiates on the principles of ecological city's green area system; what's more, it researches into the principle of ecological texture of the city's extensive space planning, which aimed at the oxygen source place and green area of the city's extensive space, the air alleyway and air circumfluence and the city's layout pattern at the angle of meteorology, environmental science and source of city planning, Take Hengyang city for example, we can study the space structure of its ecological green areas and the layout pattern of urban green area system and feasible green area target system if applied with ecology and the principle of modern city planning and landscape garden, based on territorial planning and regional planning and city's over-all planning, in accordance with the city's afforested area actualities and the society development economic conditions.
