Abstract:At present, many forest parks in China are facing the prominent contradiction between the rapid increase of tourism development intensity and the aggravation of ecosystem vulnerability. How to construct a quantitative evaluation model to achieve the scientific delineation of the development boundary has become the focus of academic circles. Taking the core scenic area of Guan'egou National Forest Park in Longnan City, an important node of Qinba biodiversity ecological function area, as the research object, seven core ecological factors including road buffer zone, elevation, slope, aspect, water buffer zone, vegetation coverage and land use were selected as evaluation indexes, and the comprehensive evaluation results of ecological sensitivity in the study area were obtained by using analytic hierarchy process (AHP) and geographic information system (GIS). The analysis results show that the most important factors affecting ecological sensitivity are slope and vegetation coverage, followed by water buffer zone, elevation, land use, road buffer zone and slope direction. The ecological sensitivity of Guan 'egou National Forest Park showed a significant gradient distribution: the areas with low sensitivity and lower sensitivity were mainly distributed in the north and northeast, accounting for 38.28 % of the total area; the moderately sensitive areas are mainly concentrated in the middle and lower parts, accounting for 27.38% of the total area. The highly sensitive area and medium-high sensitive area accounted for 34.34%, mainly concentrated in the south and southwest of the park. Based on this, this paper puts forward the strategy of 'zoning control and hierarchical protection', clarifies the functional positioning and development intensity of different regions, and puts forward specific protection and development measures.
