| China is a mountainous country, mountainous area accounts for two-thirds of the total land area,where,population accounts for about the half of chin, Mountain town accounts for about half the total town.So, it is breadth and catholicity to taking the mountainous city for example to study the accessibility of the green space in city. A lot of green space accessibility is based on the research of Plain city, the research about the mountain city is not very much.The "service radius" is a simple two-dimensional distance, and was ofen used in the past, it only considered the radiation range of flat green park, and lack of fair evaluation about green space's distribution and service functions.This methods can't truly reflect the the effectiveness for the residents of the parks'service, and it is unreasonble especially for those mountainous city which has complex transport.Since 1980s, the "garden city", and "shan-shui city" city Park green area per capita, ratio of green space and percentage of greenery coverage the "garden city", and "shan-shui city". This the standards can help us master the quantity features of urban green space from the overall,but it didin't consider the enjoyment of inhabitants which these green actually services provided.It did not reflect the position, and also not consider the fairness of public use and efficiency.With putting forward of the concept of "space accessibility" ,people begin to pay close attention to accessibility of green space.It is the important index that If every citizen can get the benefit from the green space conveniently and fairly to the development of city's sustainability environment, It is also the one of three targets to ecological garden city which include improving the environment, developing the economics, realizing social equality.Therefore, This paper attempts to establish a suitable method for Mountain Parks planning, hoping to strengthen the construction of green parks and green space close to mountain residents, easy to reach the public, using high frequency, the public can participate in strong and really play city Parks leisure and entertainment role.The paper first involves the concepts of specific interpretation, Mountainous city park green space is defined accessibility for people to use a specific transportation systems from a given location overcome the resistance to the space of mountainous city park greenbelts absolute or relative degree of difficulty.It reflects the resistance that people need overcome when they reach mountainous city park green spacee,we can use transportation time, cost, and the attraction between starting point and destination station to describe. Then we review the some reasearch about mountainous city park green space home and abroad.We found little research about this. And almost all tend to landscape direction of the research on the park green space system planning, overall layout of study hardly. Then the paper introduces park green space accessibility research trends, w e find the park green space's accessibility of research on many scholars have long and continued enthusiasm and attention. So far,there has some effect of those tentative research on park green space's accessibility.Secondly,we analysed the particularity of accessibility and summarized.We drew a conclusion that Mountain city's topography is relatively complex, city residents' main modes of transportation is walking and bus, urban residents travel cost is not proportional to distance.This Provides the prerequisite for choosing suitable method to analysis mountain city park green space accessibility. Through the analysis and comparison of several common space accessibility analysis method,we find that network analysis can simulate realistic travel route,it is better to reflect the road network to accessibility,it is a more accurate method of space accessibility analysis.We explained and the function and principle of the method of network analysis which used in the space accessibility analysis.Then we introduces the accessibility of spatial analysis of GIS technology platform and the functional in the space accessibility analysis.We give detail of network analysis of GIS operation procedure and method of network topology and interpret network analysis, GIS platform and mountainous city park green space layout of the relationship.Thirdly,the paper use the theory of network analysis,and use GIS for technical su pport, built up of space-based mountain Parks layout procedures. Including the park gr een space up to the status quo analysis and evaluation model of construction methods a nd steps described based analysis of mountain city park green space accessibility status of the steps. On how to determine the initial planning Parks workflow discussed in det ail, and the introduction of iterative principle to Parks program to determine the final pl anning process, the initial planning of space on the accessibility of the iterative analysi s, obtained The final Green Space Planning.Finally,Wanzhou District Park in accessibility based on spatial layout of the moun tain park green space layout procedures carried out in practice, and the layout of the ra dius with service-based program space based on the comparative analysis.
