Study On The Design Of Urban Pocket Park Based On The Theory Of Sponge City

A series of problems appeared as the city's high-speed expansion,city:including the damage of natural resources,urban heat island effect is getting severe,residents' suffer from mental illness,urban water supply and demand are imbalance.Building a adjust microclimate pocket park in the city become a hot spot,and the concept of city used to sponge on city water and rain water play a important role,.how the sponge city concept combined with city pocket parks,flexible adaptability to improve response to natural disasters of cities,and with examples in this paper,become one of the research starting point.Articles analyze urban park,urban pocket park concepts,which can be traced to the development process of the change and development of the guidance idea,for example is given to illustrate its shortage,put forward the sponge city concept of pocket parks construction and design of enlightenment.According to the characteristics of the sponge city with pocket park features of the theory of three cities sponge pocket park designing principles,which include the design which has the function of ecological pocket park as the core,based on pocket parks with the regional characteristic and pocket park with humanism as the goal.Article is in term of the characteristics of the pocket park and city from three angles to explore the principle of the sponge city concept pocket park design strategy:At the first angle for site selection point of view is based on the "population density,the surrounding environment requirements,organic distribution" under the framework of expounds respectively,embodies the sponge cities and the necessity and possibility of combining pocket park;The second aspect for pocket park facilities configuration,is in term of the principle of operation of the rainwater storage facilities and the characteristics of the pocket park is divided into water storage facilities,water purification facilities,multi-function facilities;The third aspect for rainwater storage mode,rainwater storage mode can be divided into 3 kinds: single regulation mode,the overall regulation mode and external collaboration to regulate,respectively expounds the mode characteristics.And pocket in nanchang city chaoyang state park as a case study practice,through the study of rainwater storage facilities in use pocket park,to the practice of the above theoretical study and feedback.Article is based on the concept of sponge city pocket guide city park design research,at the same time combined with low impact factor of the influence of development concept and alleviate the pressure of the crowd,theoretical guidance to pocket chaoyang state park,practice feedback and supply theory,urban public green space of make the city better.
