Spatial Distribution Characteristics Of Reservoir-type Tourist Attractions And Their Influencing Factors

Reservoirs are multifunctional,and with the continuous development of social economy,their leisure and tourism functions are becoming prominent.There are many reservoirs in China,and reservoirs are the main carrier of water conservancy tourism and the core resources of reservoir-type tourist attractions.At present,there are few studies on the spatial distribution characteristics of reservoirs and reservoir-type tourist attractions in China.The spatial distribution characteristics can reflect the development law of things,and the research on the spatial distribution characteristics of reservoirs and reservoir-type tourist attractions can help the sustainable development of reservoir tourism in China.This study takes large and medium-sized reservoirs and reservoir-type tourist attractions in China in 2020 as the research subjects,takes spatial analysis techniques and measurement methods as the main supporting means,explores the spatial distribution characteristics of large and medium-sized reservoirs and reservoir-type tourist attractions and the influencing factors through kernel density estimation and spatial autocorrelation,constructs ordinary least squares and geographically weighted regression models to explore the main driving factors,and finally the problems in the development of reservoir-type tourist attractions are analyzed,and corresponding suggestions are put forward in a targeted manner.The main results are as follows.(1)Large and medium-sized reservoirs are clustered and distributed nationwide,with obvious and uneven spatial distribution differences.On the regional scale,they are mainly distributed in the southern region;on the provincial scale,they are mainly distributed in Hunan,Guangdong,Hubei,Jiangxi and Guangxi;the high-density clustering area of large and medium-sized reservoirs is mainly the north-south vertical clustering from Hubei to Guangdong;the spatial distribution of large and medium-sized reservoirs shows obvious autocorrelation.(2)The spatial distribution of reservoir-type tourist attractions is uneven,on the provincial scale,mainly concentrated in Hunan,Shandong,Jiangxi,Hubei,Henan;the number of types,the largest number of distribution of National Water Parks,National Wetland Parks are second,and prototype-zone of national ecotourism attractions are the least;the high-density agglomeration area of reservoir-type tourist attractions is mainly the east-west horizontal distribution of Guizhou,Hunan and Jiangxi,with the emergence of multi-core center agglomeration characteristics;the spatial distribution of reservoir-type tourist attractions also shows obvious autocorrelation,with local high-high agglomeration areas mainly in Hubei,Hunan and Jiangxi.(3)The factors affecting the spatial distribution of large and medium-sized reservoirs include topography and geomorphology,river systems,average annual precipitation,population density,regional average GDP,and transportation location,etc.The empirical analysis shows that average annual precipitation and transportation location have significant effects on the distribution of large and medium-sized reservoirs.The factors influencing the spatial distribution of reservoir-type tourist attractions include large and medium-sized reservoirs,topography and geomorphology,river system,average annual precipitation,population density,regional average GDP,and traffic location,etc.More tourist attractions are distributed in areas with lower elevation and gentler slope,as well as more precipitation,more tourist attractions in areas with medium population density and less developed economy,and the number of tourist attractions built near major roads is also more obvious.The empirical results show that the number of large and medium-sized reservoirs,the average slope and the traffic location have significant effects on the distribution of reservoir-type tourist attractions.For the better development of reservoir tourist attractions in the future,according to the relevant analysis of this study,it is proposed to investigate reservoir resources,do a good job in spatial planning reservoir-type tourist attractions and optimize the development pattern;strengthen coordination and cooperation,expand and integrate related resources;strengthen traffic accessibility and improve the accessibility of tourist attractions,etc.
