| In the context of the era of national fitness,there has always been a problem of balancing "sports" and "parks" in the construction of sports parks.The study of sports performance in sports parks is not only about how to better meet the practical needs of fitness,but also an important support for guiding planning and design in the future.Measuring the effectiveness of space through crowd sports is the theoretical basis for studying the performance of sports parks.According to project types and attributes,sports park space is divided into three unit space carriers: sports,daily exercise,and leisure and entertainment.Three quantitative indicators are used: activity volume,activity density,and per capita activity volume,Following the concept of "unit space delineation-investigation of sports composition elements-quantification of sports performance",the quantitative research in Chapter 4 is conducted.The action path of the sports support system is analyzed at the level of sports demand,in order to analyze the spatial elements that affect sports performance in Chapter 5.This article takes the main urban area of Chongqing as an example to conduct a general survey of 9 comprehensive sports parks that have been built,studying the relationship between sports parks and the surrounding built environment.It analyzes the basic sports service capacity of sports parks from three aspects: sports carrying capacity,functional complexity,and sports openness.Finally,Shizishan Sports Park,Jianghe City Sports Park,Jianlanxi Sports Park,and Huangjueping Sports Park were selected as typical research objects.Taking the main urban area of Chongqing as an example,this article conducts a general survey of 9comprehensive sports parks that have been built,studies the relationship between sports parks and the surrounding built environment,analyzes the basic sports service capacity of sports parks from three aspects: sports carrying capacity,functional complexity,and sports openness.Finally,Shizishan Sports Park,Jiangyucheng Sports Park,Gailanxi Sports Park,and Huangjueping Sports Park are selected as typical research objects.Further attempt to analyze and quantify the sports performance within the four typical sports parks mentioned above.(1)Analyze the unit area ratio.According to the characteristics of the actual geographical area,three types of unit spaces for sports parks are designated.The core unit spaces of the three parks are mainly sports units,while Huangjueping has the largest proportion of daily exercise units.The green space rate,number of sports venues,and length of fitness trails in some parks do not meet the new standards,which may be related to the complexity of the park construction itself and the actual geographical area;(2)Investigate the components of exercise performance.A comparative analysis was conducted from four aspects: total number of people,individual aggregation,type heat,and intensity contribution.It was found that Chongqing sports tend to prefer autumn in terms of exercise time,while people tend to gather on the track and field in terms of spatial distribution.Walking and running sports are the most popular types of sports throughout the time,and moderate to high intensity sports better promote energy consumption in terms of intensity preference;(3)Quantify the overall sports performance of the park.The overall sports performance of the park is in the order of Huangjueping,Gailanxi,Shizishan,and Jiangyucheng.Based on the limitations of sports parks in mountainous areas,a study was conducted on the activity density index of three unit spaces per unit area.It was found that daily exercise unit spaces have a higher performance level.It is recommended that the area ratio of the three unit spaces in sports parks be in the order of daily exercise unit>sports unit>leisure and entertainment unit;(4)Compare the performance of unit space movement.In sports units,basketball courts and five person football courts have higher levels of sports performance,which is related to their large number,high intensity,and long-lasting constituent elements.Tennis courts and badminton courts have lower levels of sports performance,which may be related to not only the constituent elements of sports,but also the insufficient attraction of the project itself;In daily exercise units,the performance level advantage of fitness trails is prominent.Although their exercise intensity is not high,they have the highest number of people,wide coverage,and long duration.The performance level of fitness squares is relatively high,due to their moderate intensity,large number of people,long duration,and rich content;The leisure and entertainment unit undertakes a large number of leisure and recreational functions in sports parks,but it is not given enough attention.In terms of sports performance,due to its single content,low intensity,lack of distinctive features,and lack of attractiveness,the sports performance of hiking trails and some leisure spaces is relatively low.On the basis of quantifying the performance of three unit spatial movements,further explore the spatial elements that affect movement performance.According to the spatial morphology,the three unit spaces are subdivided into five sports venues,and the spatial elements that affect the sports performance of the five sports venues are selected based on the sports needs of different sports types.Finally,it was found that in the sports unit space,the relevant elements of the sports field have the most complex impact on sports performance.A simple linear regression of multi-dimensional indicators cannot fully explain the obtained results in mathematics and physics.Space enclosure,number of shading facilities,number of trash cans,and type of pavement can all significantly affect their sports performance;In the daily exercise unit space,the number of signage systems,trash cans,and green visibility of fitness trails can significantly affect their exercise performance.The spatial enclosure of fitness squares,the number of trash cans,and the number of exercise equipment can significantly affect their exercise performance;In leisure and entertainment unit spaces,the average slope,width,and area of hiking trails can significantly affect their sports performance,while the green vision rate and venue area of leisure spaces can significantly affect their sports performance.Finally,a sports park optimization strategy based on improving sports performance is proposed.At the level of overall spatial pattern,based on the fundamental principle of intensive planning of sports parks under mountainous characteristics,build a unit spatial system with high sports performance;At the unit space level,it is proposed to build a sports unit space with a compact and centralized layout,optimization of venue types,balance of multi-functional venues,and supply of emerging projects.It is also proposed to build a daily exercise unit space with a compact and centralized layout,increase the number of trails for all people,promote a complex space,and care for the elderly and young,highlighting regional characteristics of leisure and entertainment space;At the level of specific sports venues,combining the sports needs carried by each unit,mathematical analysis,and example proof,the optimization strategies and specific transformation cases for typical venues are constructed from three dimensions: spatial organization,facility layout,and environmental creation. |
