The Research On The Attraction Of Public Green Land In Urban Area To Outdoor Physical Activities In Shenzhen

With the rapid development of the city, the deterioration of the environment and the change of life style becomes new public health problem. One of the most important and modifiable factors is the physical activity level, especially in the field of rebuilding the environment, promote and improve the physical activity and enhance people's health. As an important part of the building environment, the significant influence of the urban public green land on the physical activity needs more attention and further research.Based on the research state at home and abroad, “n the overall planning objectives of the "city to promote healthy life", the full use of the sports tracking software released by the volunteer geographic information, relying on geographic information system,constructed the relationship between urban public green space and outdoor slow physical activity, and analyzed activity differen ces and green land differences between carries activities and not with the data of three activities of running, walking and cycling. Then, we carried out possible influence factors of three activities, hypothesized in different level, and constructed regre ssion model to further research. Final, we found the attraction ways and factors about the influence of urban public green land on outdoor slow physical activity, and the relative influence function of green land, circumstance around green land and physica l activity. The conclusion has been drawn.In the overall level, according to the relevance analysis about the distribution of green land and physical activity based on the streets as the research unit, we proved that the physical activity distribution is better in the streets of higher distribution rate of green land, which means the green land distribution has an attractive effect on physical activity. In a more detailed classification, the urban green land has a stronger attractive effect on the physical activity than the country. Same conclusion is also drawn in the comparative analysis of specific data between the green land which carries activities and not. At the concrete level, we found that some other factors like the circumstance around the green l and has also attractive effect on physical activity compared with the green land quality itself, and they shows some kinds of competitive relationship. In another word, the higher maturity the circumstance around green land is, the lower attraction on phys ical activity green land has.
