基于职住平衡与通勤的苏州城市职住空间结构特征

摘要

就业与居住的空间平衡是城市规划考虑的重要课题。研究利用 GIS 空间分析技术，基于交通出行调查数据，从不同的空间尺度，采用平衡度指标、自足性指标以及平均通勤距离和通勤时间，测度苏州市职住空间的结构特征和职住平衡情况。研究认为，苏州市总体职住平衡处于合理范围，但由于苏州市的产业布局导致职住空间分异明显，随着城区一体化的发展，职住空间结构正在加速重组；在此基础上，研究从城市规划、城市交通和住房等城市发展政策方面提出优化苏州市职住平衡的建议，为苏州市城市规划和城市空间优化提供一定的参考。%The spatial balance between job and housing is an important issue in urban planning. The paper uses GIS technology and transportation data, measures Suzhou job-housing spatial structure from dif erent spatial scales with balance indices, self-sufficiency indices, and commuting distance and time. The paper concludes that Suzhou job-housing structure is reasonable, yet with distinctive industry-leading housing space differentiation. The paper puts forwards Suzhou job-housing balance development suggestions in urban planning, transportation, and housing policy.
