Recreational utilization pattern and influencing factors of large and medium-sized reservoirs in China
Recreation is a common trend in the utilization of reservoirs in various countries.Taking 4748 large and medium-sized reservoirs in China in 2022 as the research object,the study analyses the pattern of recreational utilization of reservoirs and its influencing factors at multiple scales.The results show that:(1)There are 636 recreational reservoirs in China,accounting for 13.40%of the total number of large and medium-sized reservoirs;the overall recreation utilization rate is low,and varies significantly among eastern,central and western regions of China,with the utilization rate of 11.14%,15.60%and 13.05%,respectively;water-related recreation area systems are the dominant type of recreation reservoirs.(2)The number of recreational reservoirs in eastern,central and western regions of China accounts for 24.21%,41.04%and 34.75%,respectively;except for Shanghai and Tibet,recreational reservoirs are distributed in 29 provincail-level regions,more concentrated in the Hunan,Hubei and Jiangxi provinces of the middle reaches of the Yangtze River,and they are distributed in 262 cities out of the 333 prefecture-level cities;92%of recreational reservoirs are located in areas with precipitation above 400 mm,the Yangtze River basin has the largest number,the river basins in southwest China have the lowest number,and the Huaihe River basin has the densest distribution.(3)The spatial structure is characterized by"one core and one belt",the one core is Shandong province and the one belt is the band area connected by cities in the Yangtze River basin including Chengdu,Chongqing,Guiyang,Changsha and Nanchang.(4)Economic and social factors are main reasons for the spatial distribution differences in recreational reservoirs,6 indicators such as the per capita disposable income in urban and rural areas,and fixed-asset investment are significant indicators;natural factors directly affect the formation of resource conditions and indirectly affect the transformation of recreational reservoirs.The study can provide a scientific foundation for improving the level of recreational use of large and medium-sized reservoirs and promoting the ecological protection and governance of important rivers,lakes and reservoirs in China.
