Ecological Protection And Utilization Of Xuefeng Mountain National Forest Park Based On Ecological Sensitivity Evaluation

In this paper,the evaluation index of ecological sensitivity analysis of Xuefengshan National Forest Park is established from four aspects of physical geography,biodiversity,soil erosion and human activities,and the index data is extracted and analyzed by the combination of geographic information technology(GIS)and remote sensing technology(RS).Based on the ecological sensitivity evaluation method,comprehensively use the analytic hierarchy process(AHP),combined with the spatial weighting and superposition function of GIS,comprehensively evaluate the sensitivity of Xuefeng Mountain National Forest Park,and divide the spatial distribution of different sensitivities.Finally,based on the evaluation results,corresponding management and protection strategies are proposed for different sensitive areas,and ecological protection and utilization ideas based on the distribution of ecological sensitivity are proposed.The main research results obtained in this paper are as follows.(1)According to the natural resources and ecological characteristics of Forest Park,four first-class evaluation indexes and ten second-class evaluation indexes were selected,including physical geography,biodiversity,soil erosion and human activities.The paper used AHP to determine the weight of each evaluation factor layer by layer.Among them,the weight of physical geography factor is 0.1222,the weight of biodiversity factor is 0.4231,the weight of soil erosion factor is 0.2273,and the weight of human activity factor is 0.2274.(2)GIS is used to make the single factor ecological sensitivity classification map,and determine the weight of each single factor ecological sensitivity classification layer for spatial weighted superposition to obtain the comprehensive zoning map of Forest Park ecological sensitivity.The results showed that the ecological sensitivity of Forest Park was mainly severe sensitivity,extreme sensitivity and moderate sensitivity,and the distribution areas were 1258.23 hectare,1012.59 hectare and 690.96 hectare,respectively,accounting for 35.77%,28.79%and 19.64%of the total area of Forest Park.(3)According to the comprehensive evaluation of ecological sensitivity,this paper puts forward some ideas for the eco-tourism planning of Forest Park.Compared with the subjective judgment method of the overall planning of Forest Park,it is more conducive to realize the unity of protection and development,and promote the high-quality development of Forest Park.
