The Environmental Bearing Capacity Of Heishan Shilin Scenic Area Ecotourism

With the increase for tourism activities in recent years,the number of tourists in scenic spots has become larger and larger,as a result,not only the economic benefits have grown,but also the environment problem caused by human activities in scenic spots.The destruction of force.This paper analyzes the current status of ecotourism development in the Heilin Shilin Scenic Area,and uses a multi-index system and a weighted comprehensive evaluation method to qualitatively analyze the ecotourism environmental bearing capacity of the Heilin Shilin Scenic Area.The main research results are:(1)A four-level indicator system for assessing the ecotourism environmental bearing capacity of the Heilin Shilin Scenic Area is composed with 1 target level,3 criterion levels,8 field levels,and 20 indicator levels.The target level(A)consists of natural environmental carrying capacity(B1)、 the social environmental carrying capacity(B2)and the economic environment carrying capacity(B3).(2)Using the analytic hierarchy process to determine the weight of each index in each layer: the weight of the natural environment bearing capacity in the guideline is 0.6144,the weight of the economic environment bearing capacity is 0.1172,and the weight of the social environment bearing capacity is 0.2684.The weight values of the environmental carrying capacity,the ecological carrying capacity,and the spatial carrying capacity of the tourism resources under the bearing capacity of the natural environment are: 0.5278,0.3325,and 0.1396.The weight values of the carrying capacity of tourism service facilities,the carrying capacity of tourism infrastructure,and the carrying capacity of tourism management under the economic environment bearing capacity are: 0.1919,0.1744,0.6337.The weight values of social psychological carrying capacity and social cultural carrying capacity under social environmental bearing capacity are: 0.6667,0.3333(3)Using the weighted comprehensive evaluation method,the comprehensive evaluation value of the ecological tourism environmental bearing capacity of the Heilin Shilin Scenic Area was calculated to be 0.7173,belonging to a lightly overloaded state.It shows that the Heilin Shilin Scenic Area is highly developed and utilized,and its sustainability is poor.(4)It is concluded that the limiting factors for the carrying capacity of ecotourism environment in the Heilin Shilin Scenic Area are mainly the water quality of the viewing water,the occupancy rate,the carrying capacity of the land resources,the spatial carrying capacity of the water resources,the catering capacity and the management team.This puts forward measures to optimize the treatment facilities for tourist sewage inside the scenic spot,properly control the number of tourists,and try to resettle local residents for employment in scenic areas,etc.,in order to realize the sustainable and healthy development of the Heilin Shilin Scenic Area.
