Research On Accessibility Of Greenway Based On Contingent Valuation Method

There is an important plan named "198" put into practice during the construction of garden city in Chengdu. It will be used to control the unlimited extend of city’s construction.198area includes198km2land which surround the city central. It reckon that198greenway will be the demonstration project and198area will be intake to clean the air of city as the lung of human’s body. It is essential to use a professional evaluation system to check if the greenway meet both of the physical and mental need of public.it means to make the construction better and resolve the conflict between environment and human beings for improving the quality of life.On the basis of practical and computer aided analysis, this task intend to build an evaluation demo for reflecting weather the greenway meet the need of public transport, landscape, services and safety. How about the efficiency? If the public satisfied with the quality of life, It will be great if this task can be useful for improving the construction plan to be more hommization.In conclusion:(1)the accessibility of greenway is not enough, At the moment, the function of greenway is not perfect for people’s daily life but only for limited area.(2)Most of the investigators hold thevie that landscape environment is the top one, the following are:safety system, infrastructure and improvement of services. Unfortunately, the fact is:landscape and services are much better than the safety and infrastructure.(3)The safety and infrastructure have not achieved the required standard, compared with them, landscape construction and services nearly reach it.(4)The evaluation system is viable for judging the necessity and rationality of the garden City system. It shows clearly what the public respect for the accessity of greenway and what need to be done in the future.
