针对农村公路与区域社会经济协调性评价问题,分析了农村公路协调发展影响因素,采用主成分分析法构建评价指标体系,以可拓学、关联函数为基础,构建综合物元评价模型,将复杂多指标评价转换为单目标评价,通过计算综合关联度,对农村公路与区域社会经济协调性做出评价,最后将模型应用于青海省海东地区。评价结果表明:海东地区农村公路与社会经济协调发展的综合关联度为0.3687,处于不太协调状态,符合目前海东地区农村公路与社会经济的发展现状。
In order to evaluate the coordination between rural roads and regional socio-economic development, this paper analyzes the influencing factors of the coordinated development of rural roads, and constructs the evaluation index system by using principal component analysis. Based on extenics and related functions, it constructs the comprehensive matter-element evaluation model, The multi-index evaluation is converted into a single-objective evaluation. By calculating the comprehensive correlation degree, the rural highway and regional social-economic coordination are evaluated. Finally, the model is applied to the Haidong area in Qinghai Province. The evaluation results show that the comprehensive correlation between rural roads and socio-economic development in Haidong is 0.3687, which is in a less coordinated state, which is in line with the current development of rural roads and social economy in Haidong.
