The Route Selection Research Of National Trails System

National trails system is developed by the Chinese Mountaineering Association, issued by the State Sports General Administration, the national trails system building responds to the State Council issued "on accelerating the development of sports industry guidance." National trails system refers to the basic approach built on the mountain, to the fitness for purpose of the trail. In 2009, the first national trail-Ninghai trail was built in China, due to China’s national trail construction is still in its infancy, the relevant theoretical research is still very weak. The route selection is the first steps of national trail in the planning process, directly affect the next planning and visitor experience. Thus, the paper decided to start with the route selection, using literature review, field survey method, questionnaire and mathematical statistics, etc., combined with landscape ecology theory and recreation Opportunity spectrum, based on the existing trail sections sort conduct research. Include the following three aspects:Firstly, on the basis of relevant theories and research literature, respectively research the relationship between the environment (object) climber (body) and the route selection. In the study for the environmental point of view, the paper use landscape ecology extracted impact factor as elevation, slope, aspect, topography, soil conditions, hydrology (flood) and soon.For climbers angle, the paper based on human needs theory divided the climber into two categories, and studied the behavioral characteristics of two types of climbers, extracted the impact factor as landscape types, landscape grading, recreation time, climbing difficulty, availability and potential danger.Secondly, the paper constructed the route selection models based on the existing sections of the trail. Built the national trails Recreation Opportunity Spectrum (includes two types of trails, as well as to define the relationship between the two factors). Determined the classification index.Finally, this paper took Beijing Shunyi shallow mountainous national trail as an example, carried out field survey of its current status of all sections of the trail, ecological sensitivity analysis, according to the classification of indicators to assess and analysis each sections of the status quo trails, ultimately select two kinds of trail types of trail routes.
