Research On Urban Green Space System For Healthy Recreation

City is the living environment of the people where human civilization gestates from. But with the quick development of industrialization and the urbanization process becoming more and more serious, human's activities bring about living environment crisis to human being. Because of such reasons as exploiture not properly and lack of overall urban planning, the intrinsic ecological environment was destroyed, and also, the urban green space can't bring ecologic and environmental benefits into effect and the mechanism of environment doesn't work as a result.Sustainable development of the city has already turned out to be the goal of urban and region planning in the 21's century. A research project was put forward on building the ecological green space system by connecting urban ecological corridors effectively. It is needed to increase the area of urban green space limitedly and at the same time use the present roadside green space and linear park to build greenway system in order to connect the disperse green space in the city and form a ecological networks, known as urban green space system for healthy recreation, which need combine different functions of parks and other green space, such as recreation, health, traffic, and so on.A method of Multiple Criteria Decision was proposed to build factor evaluation system of Urban Green Space System for Healthy Recreation, in which land feasibility of urban roads ware evaluated by such aspects as ecological protection, recreation and traffic. The results can provide the foundation for methods of connecting greenways and planning the green networks reasonably.Our research focus on the main downtown area in Zhu Hai city as a example of object and the results as below:(1) AHP means are used to evaluate every factor of greenway given different power, by which we find that when referring to the urban green space system for health recreation mostly of ecological protection and recreation and traffic functions, experts prefer concerning function of ecological protection and think it the most important of all, and recreation function is the second, then is the traffic function.(2) Four frameworks including ecological protection, recreation, traffic and...
