Research On The Planning And Design Of Pocket Parks In Zhengzhou

With the rapid development of modern city, urban building density and population density are rising sharply. The pace of people’s lives is increasing as well as the working pressure is growing, but the green area of modern city is continue to decline, so the demand for green area is very urgently. Pocket park as a new kind of green space form appeared. Pocket park is a kind of small open green urban space which is spread flexibly in the high density of the city. They provide the surrounding residents and tourists who enter the park accidently with places to rest and communication directly. They scattered patchy in the high density of the city and provide places for people who live under high pressure of city life to relax and communicate. They alleviate people’s pressing needs for the green area greatly.Zhengzhou is the capital of Henan province which is a populous province and it’s known as its laudatory name--Greentown. The city greening system has already formed as dot, line and face. There are lots of green areas are needed to optimize the city structure in the rapid developing city. The appearance and development of pocket parks in Zhengzhou have closely connected with the development of the city. Pocket park as a part of the urban public green space which is small and exquisite, they can make the urban green space to be a more completed system, improve the urban eco-environment, weaken the boundary of the hard and soft landscape space. Though the construction level of Zhengzhou pocket parks is advancing with the times, there are still problems such as unreasonable design, inhumane campus facilities and poor management. They need to be improved in systematic, humanity, refinement and need a more completed improvement in theoretical guidance and practical. Zhengzhou has a long cultural history as well as the vitality of times. Cultural inheritance can be achieved by putting the cultural elements into the pocket park, humanistic care can be reflected by the infrastructure construction of the park and happiness index can be improved. Four seasons sceneries can fully show charm of Zhengzhou city in different time, dynamic or static and leave nostalgia for people. Different kinds of activities in the park also bring invigorate to city life.In the paper, advanced theory and methods of the research were collected through obtaining data, collecting related information and communicating with experts; the success of pocket parks aboard were analysed; the past experiences were absorbed; and research on planning and design of pocket parks with related field were done. The meaning of pocket park, the latest research progress at home and abroad and the research in related fields have been presented in this paper firstly. Then according to the characteristics of Zhengzhou city, the pocket park have been divided into five types:live, work, transportation, recreation and educational.10 pocket parks in the center of Zhengzhou city were took as the object of investigation, the pocket park site, the park layout, boundary treatment, people and activities of different types of pocket parks were analysed in turn through organization of data collection, on-the-spot investigation and analysis. Suggestions of the pocket park site, boundary and entrance design, the park layout, road and the pavement design, plant selection and configuration, construction and public facilities design, etc. have been put forward by professional knowledge. Sum up design principles of planning and design of pocket parks and put forward new ideas on economical design, ecological design and other aspects:construction of landscape should be built simultaneously with buildings in the reconstruction of old city and new city construction, trying to build a pocket park in every three or four blocks; entrance of the park should be identified strongly and provide specialized channels for disabled. Inside and outside of the park space should be divided by boundary and combining with surrounding environment as well; the needs of different users and more activities should be meet by different space, landscape levels can be rich through raising or lowering the terrain to improve touring experiences; water area should not be too big in north and the water reuse should be enhanced; garden road should be designed with the scene, drainage facilities should take into consideration, the slope should not be too steep and paving material should be rough and durable, cultural elements could be putted into the paving design and let people feel the culture of the city when they are in the pocket park; landscape structure can be plumped by enriching plants landscape diversity and forming greening system in the plane and elevation. Following the principle of proper optimal trees and more native plants should be planted; size and growth speed of plants should be took into consideration to form the scenery of four seasons with King; garden construction sketch public infrastructure should be fully humanized and give a certain cultural connotation, to meet visitors’physiological needs and have a deeper understanding to Zhengzhou at the same time.Finally, developing trend for the development of pocket parks and the urban landscape construction in Zhengzhou in the future were prospected. Although the studying of pocket parks began late in China, a more ecological space for people can still be made through advanced theoretical guidance, combining with advanced science and technology and policy support with humanity, science, characterization as design concept to makes Zhengzhou more beautiful with more trees and roses. I hope that the research in this paper can provide a meaningful reference in construction of pocket park in the future.
