Abstract
Take Mount Jinggang as a case study. This paper selected different target nodes such as scenic spots, highway interchanges, traffic distribution centers, tourism service facilities. Due to the specialty of study area, we divided geomorphic units by auto-extraction method based on DEM. Considered influences of speed indicator caused by terrain. Adopted weighted average travel time evolution model. The accessibility results show that: 1) The general level of accessibility is well, but there exist significant differences between nodes. 2) The spatial distribution of accessibility follows distance attenuation regular, and attenuates slowly along the high grade road. 3) The spatial distributions of accessibility are anastomosed with terrain spatial patterns greatly.
