【摘要】：为获取连片特困地区综合交通可达性与贫困程度的空间耦合特征,基于空间截面数据,构建了因子分析—熵权多维贫困测度模型、综合交通可达性评估模型和空间耦合协调模型,并以滇西边境山区为例进行分析验证.结果表明:整体空间上,贫困程度表现出由中心向外围扩散的模式,呈现南部高于北部、边缘高于中心的空间特征;综合交通可达性空间分异显著,可达性值呈"偏左正态分布",并在主要节点形成了"Y字型"综合交通可达性优势带;贫困程度与综合交通可达性的耦合协调水平两极化特征明显,中心区域及边缘地带上的空间耦合关系显著,协调发展水平较高;其他县域耦合协调发展水平偏低,交通基础设施的扶贫效应有待发挥.
[Abstract]:In order to obtain the spatial coupling characteristics of the comprehensive traffic accessibility and poverty degree in the special hardship areas, a multi-dimensional poverty measurement model with factor analysis and entropy weight is constructed based on the spatial cross-section data. The integrated traffic accessibility assessment model and spatial coupling coordination model are integrated, and analyzed and verified by taking the western Yunnan border mountain area as an example. The results show that the poverty degree in the whole space shows a pattern of spreading from the center to the periphery, which is higher in the south than in the north. The spatial characteristics of the edge are higher than the center, the spatial differentiation of the comprehensive traffic accessibility is significant, the reachability value is "left-handed normal distribution", and the "Y-shaped" comprehensive traffic accessibility dominant zone is formed at the main nodes. The coupling and coordination level between poverty degree and comprehensive transportation accessibility is obvious, the spatial coupling relationship between the central region and the edge area is obvious, the level of coordinated development is relatively high, and the level of coupling and coordination development in other counties is relatively low. The poverty alleviation effect of transportation infrastructure needs to be brought into play.
