Calculation and influencing factors of karst cave environmental carrying capacity based on three-dimensional model:a case study of Sanjiao Cave in Jiuxiang,Yiliang,Yunnan
摘要
Abstract
In view of current situation of insufficient research on the theme of environmental carrying capacity of karst caves,Sanjiao Cave in Jiuxiang,Yiliang,Yunnan is taken as an example to obtain karst cave point cloud data through terrestrial laser scanning and establishes a fine three-dimensional model.According to the require-ments of tourism cave planning and designing,the initial model is cut and extracted by using the height of safe water level in study area,and the lower model of safe water level is removed to obtain the tourism cave space mod-el and accurately calculate the size of tourists'sightseeing space.On this basis,considering various cave environ-mental influencing factors such as CO2 concentration,heat,light and river,the traditional ecological environment capacity method is improved,and the mathematical model of karst cave environmental carrying capacity based on three-dimensional model is established to calculate the maximum environmental carrying capacity of undeveloped caves,so as to better guide the development and design of karst caves.Compared with the traditional calculation method,it is found that heat is the most limiting factor of environmental carrying capacity of cave tourism.At the same time,according to the calculation results,the maximum difference in instantaneous bearing capacity is 19 146 people,and the maximum difference in daily bearing capacity is 123 189 people.The calculation results are more scientific and reasonable,more in line with the actual situation.关键词
