| At present,China vigorously promotes cultural revitalization,promotes China’s excellent traditional culture,and protects material and intangible cultural heritage more and more urgent.In the era of universal tourism,the canal cultural heritage resources and tourism will be integrated and developed,the canal cultural heritage resources will be protected and utilized,and the canal cultural scenic spots will be developed,which will be beneficial to the utilization and protection of the canal cultural heritage resources and accelerate the spread of canal culture among the masses.Speed,stimulating the public’s cultural identity and acting on the protection of the canal’s cultural heritage.This study will take the Jiangnan section of the Grand Canal as the research area,select the canal heritage tourism resources in the study area,that is,the canal scenic area as the research object,and analyze the research tourist space structure based on the heritage corridor theory.With the help of GIS software,the database of canal scenic spots in the south section of the Grand Canal was constructed,and the visual data processing of the canal scenic spots in the database was carried out.Based on the spatial metrology method,the spatial distribution characteristics of the canal scenic spot and the spatial transportation network characteristics of the canal city were analyzed.Based on the social network analysis method and UCINET software,the spatial structure of the spatial tourism economic association network of the canal tourism city in the region is analyzed.Based on the "point-axis" theory and the core-edge theory,the optimization of the tourism space structure of the canal heritage corridor in the southern section of the Beijing-Hangzhou Grand Canal is proposed.Based on the canal axis and the traffic line,a hierarchical optimization scheme is proposed for the transportation space structure of the heritage corridor tourism.Based on the elements of urban tourism economy and other aspects,the development of integrated canal tourism development is optimized.This paper draws the following conclusions:(1)There are 61 canal scenic spots in the Jiangnan section of the Beijing-Hangzhou Grand Canal,with a low overall development and utilization level.The canal scenic area has a cohesive distribution in the whole area,but the spatial distribution of the canal area is uneven among the canal cities.The utilization of the three cities of Suzhou,Wuxi and Jiaxing is the most concentrated;in the combined effect of the canal scenic area Suzhou City is more prominent,and the cultural heritage resources of the canal covered are more diverse.(2)The tourism economic spatial correlation network density of the seven cities in the southern section of the Beijing-Hangzhou Grand Canal is relatively low,and the overall lifting speed is relatively slow,which is greatly affected by the geographical distance.The three cities of Suzhou,Wuxi and Hangzhou in the region have certain control and radiation power to their surrounding cities.Traffic access between cities in the region is high.(3)Canal tourism in the southern section of the Beijing-Hangzhou Grand Canal can be optimized for “networked structure” and “dual-core structure”.In the “networked structure” optimization model,Suzhou is a first-class core city,Wuxi and Hangzhou are secondary development cities,Changzhou and Jiaxing are three-level development cities,and Zhenjiang and Huzhou are four-level development cities.The tourism association between the canal cities was strengthened from the two aspects of canal culture and transportation,and the network structure of the regional heritage corridor tourism space structure was accelerated.The “dual-core structure” model has established cores for Jiangsu Province and Zhejiang Province respectively.Jiangsu Province has Suzhou as the core city and Zhejiang Province has Hangzhou as the core city.Based on the above research conclusions,combined with the heritage corridor theory,the countermeasures are proposed from the point,line and area of the Grand Canal Heritage Corridor to the regional spatial structure optimization.According to the distance from the canal scenic spot to the main axis of the Beijing-Hangzhou Canal,The transportation network structure of the canal in the south section of the canal is optimized to three levels.According to the core position of the canal city in the spatial structure of the regional tourism economy and the spatial distribution characteristics of the canal scenic area,the development of inter-city tourism between the canals is proposed.Tourist area: the canal industrial heritage tourist area,the canal ancient town tourist area and the canal cultural tourism area provide a theoretical basis for the optimization of the tourism spatial structure of the Jiangnan section of the Beijing-Hangzhou Grand Canal. |
