Study On The Tourism Environmental Carrying Capacity Of Changchun Diao Shuihu National Forest Park

From the beginning of reform and opening up,China’s economy has entered a stage of rapid development,and the national GDP per capita has increased year by year.The main contradiction of residents has changed from solving food and clothing to the pursuit of spiritual level.The demand for tourism is becoming stronger and stronger.The domestic tourism industry has entered a stage of rapid development As a result of the surge in tourism activities,the impact of tourist destinations has become stronger.When a tourist destination is overloaded,it will not only cause irreversible damage to the destination’s own tourism resources,but also reduce the tourist’s tourist satisfaction,reduce the tourist’s evaluation of the tourist destination,and make the tourist experience poor.The sustainable development of the destination has a negative impact.In order to protect the sustainable development of the scenic spots in the forest park,increase the tourist flow of the scenic spots and realize the purpose of revitalizing the local villages,this study builds the national forest of hanging kettles from the actual situation of the scenic spots such as the four criteria of nature,resources,economy and psychology of the hanging bottle national forest park.The index system of the park’s tourism environment carrying capacity uses AHP to analyze the index weight of the whole Hanging Kettle Scenic Spot,and collects the background values of the cave’s internal volume,CO₂ content and calorific content of karst caves and ice caves through field visits.Calculate the tourism environmental carrying capacity of cave tourist attractions,study the tourism environmental carrying capacity of hanging kettle scenic spots,provide data support for the sustainable development of Hanging Kettle National Forest Park,and provide suggestions for the future development direction of hanging kettle scenic spots.This type of scenic area provides scientific basis for tourism resource development and ecological environmental protection.The specific research results are as follows:（1）The field survey method,literature review method,expert consultation method,and analytic hierarchy method were used to construct the evaluation index system of eco-tourism environmental carrying capacity according to the current situation of the scenic spot and calculate the system,and the ecology in combination with the regional situation of the scenic spot were analyzed.The current status of tourism environmental carrying capacity,and the development model of the scenic area were used to develop plans to strengthen the utilization of the carrying capacity of the scenic area.According to the wooden barrel theory,the minimum value of each sub-capacity of the eco-tourism environmental carrying capacity were used as the selection index.The natural environmental carrying capacity（NEBC）is 8400 people/day.The resource and environmental carrying capacity（REBC）is 5600 people/day.The economic environment carrying capacity（EEBC）is 240 people/day and the social environment carrying capacity（SEBC）is 4648 people/day.The analytic hierarchy process was used to draw the conclusion that the daily carrying capacity of the eco-tourism in the Diao Shuihu national forest park was 6,160 people and the annual carrying capacity of the eco-tourism environment was985,600 people.The current tourism development of the Diao Shuihu National Forest Park has not yet entered a period of rapid development.The infrastructure of the scenic area is not complete and the tourism reception facilities have not yet formed a scale.The theoretical carrying capacity is calculated to be greater than the existing ecological tourism environmental carrying capacity of the scenic area.At present,it is necessary to form an integrated development model of scenic spots and villages based on scenic spots as soon as possible;do a good job of highlighting publicity to increase the popularity of scenic spots;and improve tourism service facilities and infrastructure.（2）The tourism environmental carrying capacity of caves and ice caves was calculated by monitoring the CO₂ concentration and temperature in the cave spots.According to calculations,it was known that the carrying capacity of the Diao Shuihu cavern tourism environment was large and the cave was in a state of sparse loading;the ice cave was restricted by the passage of the tour route and the tourism environment carrying capacity was small.The results showed that the scenic spot as a whole was in the initial stage of imbalanced development and underdevelopment.According to the current problems of cave tourism in the Diao Shuihu forest park scenic spot,ecological planning suggestions were proposed to provide theoretical support for the sustainable tourism development of cave landscapes.
