| Jiangsu,Zhejiang and Shanghai have abundant hilly resources and suitable outdoor mountaineering fitness conditions.Under the background of national fitness,as an important place for the public to get close to nature and keep fit,urban hilly mountaineering fitness trails in Jiangsu,Zhejiang and Shanghai are increasingly favored.At present,the research on the suitability of hilly mountaineering fitness trail construction is still in the exploratory stage.In this paper,23 hilly mountaineering fitness trails in Jiangsu,Zhejiang and Shanghai are selected for field investigation,and their current characteristics are analyzed from the following four aspects:the layout and form of the trails,the relationship with contour lines,the characteristics of interface composition and internal factors;14 evaluation factors are selected from four dimensions based on the behavioral needs questionnaire of mountaineers,and the hilly mountaineering fitness steps are constructed by AHP analytic hierarchy process.The suitability evaluation system of road construction is to evaluate and analyze the factors suitability,comprehensive suitability and comprehensive index of hilly mountaineering fitness trail of 23 sample trails,and then to put forward optimization suggestions,aiming at guiding the construction of hilly mountaineering fitness trail to a safer,more comfortable,healthier and eco-friendly direction.The main conclusions of the study are as follows:(1)Based on Maslow’s hierarchy of needs theory and the planning criteria of national forest parks,scenic spots and other scenic recreational sites,the factors influencing the suitability of hilly mountaineering fitness trail construction are screened according to the basic requirements of the trail,adhere to the bottom line of ecological protection,meet the needs of mass fitness and embody the characteristics of Hilly activities;and the factors influencing the suitability of hilly mountaineering fitness trail construction are selected from the aspects of Four dimensions were used to construct the suitability evaluation model of hilly mountaineering fitness trail construction.The order of construction suitability weight is environmental friendliness(0.3457)>efficacy(0.2905)>Comfort(0.2878)>safety(0.0760).(2)Suitability ranking of hilly mountaineering fitness trail construction in Jiangsu,Zhejiang and Shanghai areas is as follows:humanistic experience type trail>scenic and tourist type trail>mountaineering challenge type trail;comprehensive suitability of humanistic experience type trail N_β=3.87,which is grade II(good)level;comprehensive suitability of ornamental type trail N_β=3.44,which is grade III(medium)level;comprehensive suitability of mountaineering challenge type trail N_β=3.05,which is grade III(medium)level.Compared with the scenic and mountaineering challenging trails,the humanistic experience trails have more class I(excellent)trails.(3)Based on the analysis of the current characteristics of the trails and the evaluation results of construction suitability,the optimization strategies are put forward from five aspects:safety facilities,inter-trail connection,recreation facilities,ecological protection and fitness attraction.Then,based on the evaluation model of construction suitability,the route selection of the mountain-climbing fitness trail is optimized for Sheshan Road in Shanghai. |
