A Study On The Accessibility Of Beautiful Villages Based On GWR Model

The construction of a beautiful village is an objective requirement to implement the construction of a beautiful China and realize the Chinese dream.Scientific research on the accessibility of beautiful villages is an important means to improve the rural ecological environment and develop urban and rural tourism markets.In this study,the accessibility of 43 beautiful villages in Changzhutan area of Hunan Province from 2016 to 2018 was selected as the explanatory variable.Four explanatory variables were selected: altitude elevation,road network density,shortest distance near water,and location slope to construct an OLS regression model.initial analysis.Based on the analysis results of OLS regression model,a GWR model for accessibility of beautiful villages in Changzhutan area is further constructed.Finally,the Kriging interpolation analysis method is used to visualize the contribution value of the influencing factors,and the following conclusions are drawn:(1)The spatial distribution of beautiful villages in Changzhutan area is uniform and has no cliff-like distribution characteristics;(2)The accessibility level of each beautiful village varies greatly,the number of beautiful villages with 0.7 <accessibility ≤ 1 is 25(accounting for 58.2% of the total);the number of beautiful villages with 0.5 <accessibility ≤ 0.7 is 11(accounting for Total 25.6%);7 beautiful villages with 0≤accessibility≤0.5(accounting for 16.2% of the total),the overall level of accessibility is not good;(3)According to the analysis of the GWR model,it can be seen that the elevation,location slope and road network density have a relatively obvious impact on the accessibility of beautiful villages,and the villages have obvious distribution characteristics along the river.The area where the beautiful village is located is relatively low in altitude and flat.The elevation value is between 30-286 m,the slope of the location is relatively gentle,and the slope range is between 0-24 degrees;(4)The regression coefficient of elevation elevation of beautiful villages in Changzhutan area decreases from the north and south ends of Changzhutan area to the middle;the regression coefficient of road network density is larger and denser in the southern part of Changzhutan area,followed by the east and midwest The area is average.The slope regression coefficient gradually decreases from north to south.Based on the analysis results of the accessibility of beautiful villages in Changzhutan area,the comprehensive spatial distribution pattern of beautiful villages in Changzhutan area,road traffic network and tourism market,the development situation of beautiful villages in Changzhutan area,"village revitalization strategy" and other factors Three spatial strategies are proposed for differentiated development of beautiful villages,optimizing road traffic quality and spatial structure,and combining land and space planning techniques to create beautiful villages.Comprehensively improve the development level of beautiful villages in Changzhutan area and promote the integrated development of urban and rural areas.
