Atpresent，many forest parks in Chinaare facing the prominent contradiction between the rapid increase of tourismdevelopment 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 scenicarea 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 studyarea were obtained by using analytic hierarchy process （AHP）and geographic information system （GlS）.The analysis results show that the most important factorsaffecting ecological sensitivity are slopeand vegetation coverage，followed bywater bufer 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 sensitivityweremainlydistributed in thenorthand northeast，accounting for 38.28% of the totalarea;themoderately sensitiveareasaremainly concentrated in themiddleand lower parts，accounting for 27.38% of the total area.The highly sensitive areaand medium-high sensitiveareaaccounted for 34.34% ，mainly concentrated in the south and southwest of the park.Based on this，this paper puts forward the strategy of'zoning controland hierarchical protection'，clarifies the functional positioningand development intensityof different regions，and puts forward specificprotectionand developmentmeasures.
