RESEARCH ON SPATIAL PATTERN OPTIMIZATION OF WESTERN YUNNAN BORDER AREA BASED ON GEOGRAPHIC CAPITAL
How to promote the sustainable and healthy development of key development areas in the past poverty alleviation has become a key issue to be solved in regional spatial planning and rural revitalization.The principal component analysis method was used to comprehensively evaluate the geographical capital of the western Yunnan border area in 2000,2010 and 2020.GIS spatial analysis method and gravity model were comprehensively used to analyze the current spatial pattern and explore the pattern optimization scheme.The study finds that:(1)The o-verall level of regional geographic capital has improved significantly since poverty alleviation,but the level of re-gional geographic capital in Gongshan and Fugong is relatively low;The spatial accessibility of the study area shows a decreasing level with Dali City as the central circle,and the accessibility level of the capital city to the border counties needs to be further improved.The spatial pattern of the existing geographical capital varies greatly,with obvious advantages in the central region,while the radiating role of the core cities in other regions is relative-ly weak.(2)At present,the overall level of geographical capital in the western Yunnan border area is good,but the marginal area of the study area still needs to be further improved.Therefore,with the goal of boosting ge-ographical capital,the spatial pattern optimization scheme of"three cores in one area,five middle and four ax-es"is proposed,so as to strengthen regional linkages and give full play to the radiating role of advantageous cities and promote the overall sustainable and healthy development of the region.
