TEMPORAL-SPATIAL EVOLUTION OF WATER WORKS RESORTS AND SPATIAL STRUCTURAL OPTIMIZATION OF WATER WORKS TOURISM IN YELLOW RIVER STREAM
This paper,aiming at promoting a coordinated development of water works tourism in Yellow River stream,uses gravity center standard deviation ellipse,kernel density and exploring spatial data analysis method to study the temporal-spatial evolution of water works resorts in 2009,2014,and 2021 in Yellow River stream,and combines"point-axis"theory with central function index and gravity model to define the development nodes,axis and plates in water works tourism.Development of water works resorts in Yellow River stream has 3 stages.Resorts are spreading along E-W and S-N with gravity center shifting to southwest.Their distributing density shows scattering in the upper-stream and concentrating in the middle-and down-stream,high density concentrating areas are located along banks of Yellow River,Weihe River,Fenhe River and Qinhe River.Their spatial distribution generally displays a strongly positive correlation,"high-high"concentrating in Shandong province,"low-low"in Hehuang valley and partial Gansu province.Hotspots in Yellow River stream remain unchanged,while the cold spots are concentrating toward the upper-stream,and the sub-hotspots migrating to the northwestern middle-stream.Spatial structure after being optimized is composed of three levels of water works tourism development nodes,two levels of development axes and five development domains.This paper presents suggestions on differentiating domain variance,optimizing spatial pattern of water works tourism from construction status,water resources,geographic characteristics and social-cultural environment.And improving transportation,consolidating water works tourism,boosting radiation of node cities.
