Study On The Suitability Design Of Children's Play And Activity Sites In Chongqing Parks Based On Topographic Spatial Features

At present,the field has become a children's game in the park city children's social,physical and mental development and one of the important field of perception environment,with the improvement of quality of life,children for game site quality have higher pursuit,hope to have more fun and uniqueness of the game environment,the development of the society also lead people to pay attention to managing construction of the area.In mountainous city park,the terrain landscape elements as an important impact on the design of the park and children's playgrounds,at this stage we have gradually aware of the site itself good terrain space efficient use of resources can bring a huge advantage to the overall design,but how to comprehensively understand children's games,children's the connection between the site and the terrain space characteristics,further research is needed.Therefore,this article from the perspective of "suitability",in the children's behavioral psychology,space saving design,aesthetics,vigilance regulation theory and under the support of the former research literature,analysis of children's game site suitability design factors,from saving,space aesthetics,function activity levels to explore children's game activities such as ground with appropriate relationships between topographic space,in the end,find a beautiful landscape environment,economy and meet the functional requirements of mountainous city park design method of children's games venues.First of all,this study selected the 29 park in Chongqing urban area of 35 children games site on-the-spot investigation,field profiles from children's game activities,games,activity facilities and entrance design present situation,the site boundary and ground design present situation,the children's game space overall layout and landscape space utilization present situation are summarized in aspects of the status quo of Chongqing children's games in the park site information.According to the different useof vertical space,it is divided into four types of children's play space,namely single flat ground,natural slope,layered platform and compound.Second,from the economic,activity space aesthetics,function,the three levels of different land use types of children's game area for detailed analysis,sum up the main park Chongqing children's playgrounds and topographic space present situation of the suitability of problems:(1)In the economic level,site of the functional use of natural terrain space is less,field size on the use of terrain space scale do not tally with the actual demand.(2)In the space aesthetic level,the coupling degree between the form of the site and the terrain space form is not high,the suitability of children's game space attribute and the terrain space attribute needs to be strengthened,the expression of the purpose of the site function is not clear.(3)At the level of functional activities,the overall lack of fun,terrain security design is not comprehensive.And summarize the characteristics of each type of children's play space: a single flat type of children's play space did not use the vertical terrain space;The natural slope type children's play field has the least change to the original topography and landform,and the economic ecology;The three dimensional space formed between the terraces of the children's playground is not enough used in the game function.The compound children's playing field takes into account the use of both horizontal and vertical terrain,with rich spatial layers.Finally,based on the current situation,five principles for the suitability design of children's game and activity sites and topographic space in Chongqing's main urban parks are proposed,namely,the overall layout of children's game sites and the consistency principle of park topographic space.The principle that the form and scale of children's playing field are appropriate to the shape and scale of terrain space;The principle that the game activity item attribute is suitable to the terrain spatial attribute;The shaping of topographic space is dominated by utilization and supplemented by transformation,which embodies the principle of spatial aesthetics.Overall design,ensure fun and security.The following strategies are proposed from the aspects of factors affecting the suitability of children's playing fields and topographic Spaces:(1)Saving level: site layout fit the rules of terrain and game activities,site design pay attention to digging and filling balance,save investment costs;Improve the compound utilization rate of the field game space to ensure the rationalization of the size of the field.(2)Spatial aesthetics: coupling of site boundary form and natural boundary;The terrain spatial attribute should be suitable to the game activity item attribute;Thetopography is used to highlight the theme atmosphere,inject the spirit of the place and express the regional culture.(3)Functional activity level: increase adventure game activities;Ensure the safety design of the site.According to the prominent characteristics of children's game sites of different land types,specific design strategies are proposed.It is expected to provide some reference for the design of children's games and activities in mountain city parks in the future.
