Spatial Mismatch of Tourism Resources and Tourism Economy:A Case Study of Ice and Snow Tourism in altay region

Asian Agricultural Research 2024年第11期16卷 1-8页

The coordinated development of tourism resources and tourism economy is vital improve the quality and efficiency of regional *** the ice and snow tourism in altay region as an example,this study constructed an evaluation indicator system and used the methods of gravity center model,spatial mismatch index model and obstacle degree model to calculate the spatial mismatch index and influencing factors of ice and snow tourism resources and tourism economy in altay region as a whole and in each county and *** found in the study period:(i)the ice and snow tourism resources and tourism economy in altay region was synchronous in the development of time sequence,while the spatial distribution pattern was characterized by regional imbalance;(ii)at the macro scale,the spatial mismatch degree of the ice-snow tourism resource center and the tourism economic center in altay region was gradually reduced,but they were always separated from the spatial geometric center of altay region;(iii)at the micro scale,the spatial mismatch index of counties and cities in altay region was mainly negative mismatch,and the types of spatial mismatch changed in different degrees;(iv)the factors showed certain spatial differentiation characteristics in different counties of altay region,and there were some differences in the obstacles of different mismatch level areas,and the economic basis was the most frequent obstacle in different mismatch level areas of altay region.
