Analysis Of Ecosystem Service Value Changes And Ecological Compensation Of Typical Water Erosion Scenic Spots In The Middle Section Of The Northern Slope Of Tianshan Mountains Under Tourism Disturbance

Analyzed changes in ecosystem service value and ecological compensation standards under tourism disturbance,and provide a reference for the development of tourism and the construction of ecological civilization on the northern slope of the Tianshan Mountains.This paper takes typical water erosion scenic spots in the middle section of the northern slope of Tianshan Mountain(Xibaiyanggou,Juhuatai and Lujiaowan scenic spots)as the research object.Based on the survey data of sample plots,the method of combining mathematical statistics,environmental economics and functional value methods is used to quantitatively analyze the yurt.And the characteristics of the impact of tourism disturbance on plant and soil ecosystems near the tourism route,the dynamic evaluation of the change law of ecosystem service value under tourism disturbance,and the establishment of tourism ecological compensation standards applicable to the middle section of the northern slope of Tianshan Mountains.Concluded as follow:(1)With the increase in the intensity of tourism disturbance near the yurt and tourist routes,the vegetation and soil ecosystem of the Xibaiyanggou,Juhuatai and Lujiaowan scenic spots have undergone significant changes(P<0.05).In the plant ecosystem,the composition structure of the community species tends to be single,and the species importance value tends to a few dominant species;the characteristics of the plant community and the community species diversity index(except the Simpson index)all show a decreasing trend as the intensity of tourism disturbance increases;soil ecosystem except for soil bulk density,available potassium,and p H,the other soil physical and chemical properties decrease with the increase of tourism disturbance intensity;the vegetation and soil ecosystem of different scenic spots are affected by tourism disturbance in different degrees.The plant and soil ecosystem near the yurt are affected by tourism.The degree of tourism disturbance is represented by Lujiaowan scenic spots >Xibaiyanggou scenic spots > Lujiaowan scenic spots,and the vicinity of the tourist route is represented by Xibaiyanggou scenic spots > Lujiaowan scenic spots >Lujiaowan scenic spots;the plant coverage and the main physical and chemical properties of soil under tourism disturbance There is a significant correlation(P<0.05)between the plant coverage near the yurt and soil bulk density,water content,porosity and saturated water content(P<0.05),and the plant coverage near the tourist route There is a significant correlation with soil bulk density,water content and saturated water content(P<0.05).(2)With the increase of tourism disturbance intensity near yurts and tourist routes,the positive and negative values of ecosystem services show different development trends.Among them: the positive value of ecosystem services and the value of its four sub-services all show a significant downward trend with the increase in tourism disturbance intensity(P<0.05),especially the regulation service value accounts for the highest proportion,accounting for more than 51.00%;ecology;The negative value of system services showed a significant upward trend with the increase of tourism interference intensity(P<0.05).Soil nutrient losses accounted for the highest proportion,accounting for more than 83.00% of the total economic loss of water erosion;the positive and negative values of ecosystem services in different scenic spots were affected The degree of tourism disturbance is consistent.The positive and negative values of the ecosystem services near the yurt are affected by tourism disturbance as Lujiaowan Scenic spots>Xibaiyanggou Scenic spots >Juhuatai Scenic spots;the vicinity of the tourist route shows Xibaiyanggou Scenic spots >Juhuatai Scenic spots>Lujiaowan Scenic spots;Compared with soil factors,plant factors are the main driving factors affecting the positive and negative values of ecosystem services.Biomass has the greatest direct influence on regulating service values,and plant coverage has the greatest impact on economic losses due to water erosion highest.(3)With the increase in the intensity of tourism disturbance,the ecological compensation priority index and the ecological compensation amount near the yurts and tourist routes of the West Baiyanggou,Juhuatai and Lujiaowan scenic spots show a downward trend.Compared with severely disturbed areas,the ecological compensation priority index and ecological compensation amount of non-disturbed areas are in the first place.The payment of ecological compensation contributes the most to the economic development of non-disturbed areas,and ecological compensation support should be given priority.The ecological compensation standards on the northern slope of the Tianshan Mountains have low compensation standards,universal coverage,and insufficient funds for ecological projects.Therefore,it is recommended to raise the standard of ecological compensation,implement the differentiation of ecological compensation,and increase the input of ecological engineering.
