Research On The Park Green Space System In Small Mountain Cities In Northern Guizhou

In the small mountainous cities of Guizhou Province,the urban construction land is tight,the urban space layout is unreasonable,and the green space area that can be used is very limited.How to coordinate the layout of all kinds of parks to maximize their functions and ecological effects has become a problem that must be solved in the construction of green space in small mountainous cities of Guizhou Province.Park green space is the core of urban green space,which plays a vital role in the construction and development of the city.As a subsystem of urban green space system,urban park green space system can effectively improve the urban ecological environment and provide leisure and recreational garden for residents.With the rapid development of small mountainous cities,the ecological environment of small mountainous cities in Guizhou is becoming increasingly severe.At the same time,with the increase of recreational demand of residents in this area and various problems in the construction of park green space,it is urgent for us to systematically study the urban park green space system adapted to local conditions from the macro level.This paper takes the park green space of small cities in the northern area of Guizhou Province as the research object,through the quantitative analysis on the quantity,area,layout and service status as well as qualitative research on different types of the park green space in this area to sums up the main problems existing in the current situation of urban park system in northern Guizhou Province.The problems mainly include: insufficient types and quantities of park green space,unreasonable layout,poor service,high similarity,imperfect park green space system and so on.Among them,unreasonable layouts and insufficient quantities are the crucial problems,which mainly lead to the imperfection of the park system.To solve these problems,the author takes the park green space system of Chishui City as an example,and puts forward a series of optimization strategies,including: forming the urban park green space type system composed of urban and suburban parks by including the suburban green space into the urban park green space system of the city;optimizing the park green space layout by building a balanced and reasonable layout of park green space and eliminating the failure of park green space service in the built-up area;and optimizing the construction and management system of urban park green space by forming the corresponding scientific management mode for the diversified types of park green space,restoring and updating the dilapidated infrastructure.
