Reserch On The Accessibility Of Mountain Parks

Mountain Public Parks are important to people of the city activities, which not only reflected in its role in urban ecosystems is more important is to improve the quality of life, it is an important index for the city livable. Carry out social background and low-carbon eco-city in the city under the current country, so that more important role in the city park, nice urban park design and layout for the city residents can bring more comfortable and livable natural environment. In the beginning, the evaluation of urban parkland just confined to urban green space rate and per capita green parks these two indicators, but that indicators can not meet the description of urban parks and urban residents state service area, often just an evaluation city Park overall service condition, which is not able to fully reflect the rationality of the residents of the city park and the city park specific use efficiency distribution.In this case, foreign scholars first proposed the new index in Parks accessibility, over time, the domestic scholars also aware of this new evaluation method is more able to reflect the full service health city park, have toward a lot of basic research in this direction. Based on reachability analysis method, recognized at home and abroad are mainly four categories, namely, buffer analysis, the gravity model method, near distance method and network analysis methods, and in the four analysis methods currently use the most network analytical methods, through the streets of the network topology model became established, with the GIS platform for urban parks reachability analysis, this method than other methods, the method has the advantage that it is to build a network based on city streets, by people simulate different way to travel to a method for analyzing, making this method more feasible and reliable.The author is the Yuzhong District as an analysis object, select the Yuzhong District for the study, partly because the city Yuzhong District is a typical mountain terrain, and partly because the entire city as the center of the Yuzhong District inChongqing, analyzes its cities accessibility park can be more fully reflect the service status of the city park on residents. By constructing the data model library, Chongqing Yuzhong District City Park are made up of the overall evaluation and comparative evaluation, which includes an overall rating of the motor vehicle, on foot, bus and light rail analysis and evaluation, and the comparative evaluation Park at all levels, as well as various neighborhoods with the traditional buffer analysis were analyzed and evaluated. Analysis showed up Yuzhong city parks in general, showing uneven distribution of health, there are various areas that affect the accessibility of the terrain and the road network showed a more general situation.Yuzhong construction has become more saturated, in this case how to improve their region's main park accessibility of primary or overcome terrain complicated traffic system causes. Reachability analysis on the basis of the Yuzhong District Park, the main contradiction is proposed for the corresponding planning strategies and solutions. First, starting from the park itself, Yuzhong District is a typical terrain park design should take full account of mountain terrain reason, each time in the regional distribution of the region should fit existing natural conditions, the higher terrain in the northern region, should give more consideration increase the entrance to meet different people of different directions and travel modes; southern terrain is low and close to the Jialing River, it considers the construction of a large municipal park. Followed by consideration of the traffic network, on the one hand to strengthen the construction and renovation of the park near the Yuzhong District secondary roads, convenient vehicle to reach; on the other hand also to strengthen the construction of a sound walk system to facilitate the surrounding residents to cross the little road vehicle, directly to the surrounding park. Of course, the need to fully consider the spatial distribution of land use, in conjunction with urban residential land and public parks such service area can be arranged so that a balanced to the greatest extent possible to improve the accessibility of the city park to a large extent.
