Abstract: The temporal and spatial distribution and influencing factors of hiking tourism in Yunnan were analyzed by using the method of seasonal intensity index, kernel density analysis, local autocorrelation method and buffer analysis Based on GPS data of the hiking tracks based on GPS data of the hiking tracks. The results were as follows: (1) In terms of inter-annual variation, the hiking tourism in Yunnan showed obvious characteristics of growth stages; in the field of the changes during the year, Yunnan hiking tourism was seasonal, concentrated in spring and early summer. (2) The spatial distribution of hiking track had migrated from northwest to southeast with the distribution range expanding and the degree of aggregation decreasing continuously, and it had experienced "polar core" distribution-"point axis" spatial distribution-"core-edge" structure. The correlation pattern of the local area of the hiking track node showed obvious geographical differentiation characteristics, forming a spatial pattern of decreasing heat from east to west. (3) The hiking tracks were mainly distributed along lakes and rivers where there were high vegetation coverage with the altitude between 1500m and 2500m. The distribution of hiking tracks was affected by factors such as altitude, vegetation, rivers, cities, scenic spots, economy and population.
