摘要: 营造便利的生活环境,成为提高民生的有效抓手,也逐步成为衡量这座城市综合竞争力的重要指标。首先深度解读国际上 通用的Walk Score评价方法,认为其内核是步行圈生活便利的评价。然后基于Walk Score的评价思路,构建15分钟步行圈生活 便利指数的评价指标体系与方法体系,对成都市中心城区生活便利指数展开评价。最后与居民的活动空间相结合,优化了 生活便利指数分区对比的方法。结果表明:生活便利指数高于85的区域主要集中在成都市二环内,而南部新区生活便利指数 较低,即通过步行难以解决日常生活需求;中心五城区生活便利指数与人口密度的空间相关系数皆大于0.6,说明人口密度 高的区域生活便利指数也高,侧面反映了设施布局的合理性;按照人口活动区域对比各区县的生活便利指数,相较于按照行 政地域单元统计更科学,区县之间生活便利指数的差异更小。

Abstract: Building a convenient living environment has become an effective way for improving the livelihood of the people, and has gradually become an important indicator of the comprehensive competitiveness of the city. This paper first deeply interprets the international Walk Score evaluation method, and considers that its kernel is the evaluation of the convenience of the walking circle. Then based on the evaluation idea of Walk Score, the evaluation method of 15-minute walking circle life convenience index was constructed, and the life convenience index of central city of Chengdu was evaluated. Finally, combined with the residents' activity space, the method of subarea comparison of life convenience index was optimized. The results showed that the area of the convenience index higher than 85 was mainly concentrated in the second ring of Chengdu. The living convenience index of the southern new built-up area is low, that is, it is difficult to solve the daily life demand by walking. The spatial correlation coefficient between the life convenience index and population density is greater than 0.6, which reflects the rationality of the layout of the facilities. According to population activity area, the life convenience index of counties is more scientific than that of administrative region units, and the difference of living convenience index between counties is smaller.
