With the vigorous development of heritage tourism,the accelerated process of urbanization,Chinas world heritage sites are generally facing the prominent contradictions between protection and utilization.Ecogeological environment is the important foundation for the development and utilization of tourism resources in scenic spots.Eco-geological environment sensitivity analysis is to evaluate the possibility of eco-geological environment problems occurrence under the influence of natural and human activities,which has an important guiding significance for the conservation and sustainable development of heritage sites.Huangshan Mountain is one of the top ten scenic spots in China,the crown of "World Natural and Cultural double Heritage" and "Geological Park",and shoulders the important task of safeguarding world heritage,scenic and historical resources security.This paper took Huangshan Scenic Spot as the study area,30m × 30m grid for the evaluation unit,based on the analysis of the main ecogeological environment problems in study area,a two-layered evaluation index system was constructed including geological factors,ecological factors,hydrological factors,the impact of human activities and landscape value of 5 major categories impact factors,12 secondary indicators,and under the support of the "3S" techniques,these indicators were extracted,then the fuzzy comprehensive evaluation model and the analytic hierarchy process were applied to evaluate ecogeological environment sensitivity of Huangshan Scenic Area.The study area was divided into very sensitive,highly sensitive,moderately sensitive,less sensitive and not sensitive five sensitivity levels.The results showed that the not sensitive and less sensitive areas were account for more than 90% of the study area.There are relatively few tourists,tourist facilities and scattered sight spots in these places,such as Fugu management zone and northeast of Yungu management zone.Highly sensitive and very sensitive areas were account for less than 1% in the study area,and mainly distributed in the spots focused areas such as Wenquan management zone and Yungu management zone where the human activities were very frequent.The moderate sensitive areas were account for about 3%,mainly concentrated within the 200m buffer of the roads,tourist facilities and tourist attractions,and affected by human activities relatively obvious.The research also indicates that effective protection of spots focused areas and appropriate development of decentralized district in Huangshan scenic spot are important for its sustainable development.
