兼顾城市规划因素的城镇土地定级技术路线探讨——以武汉市商业用地定级为例

研究目的:基于国家行业规程对城镇土地定级因素因子及土地定级技术路线进行再认识,并提出一种兼顾城市规划影响的城镇土地定级技术途径。研究方法:采用多因素综合评价法建立地价潜力模型,揭示城市规划对土地质量的综合影响,基于模型测算结果提炼成城市规划因素因子,纳入城镇土地定级因素因子体系后参与多因素综合评价确定土地级别。研究结果:城市规划通过协调城市空间布局和综合部署各项城市建设对土地价值的空间分布及变化趋势产生了重要影响;兼顾城市规划因素的土地定级技术路线不仅能克服传统土地定级的局限,而且对现有国家规程的技术框架进行了扩展。研究结论:武汉市商业用地定级的实证研究结果验证了技术路线的有效性。

Technical Roadmap of Urban Land Grading Combining Urban Planning Factors: A Case of Commercial Land Grading in Wuhan

The purpose of this study is to discover the factors and technical roadmap of urban land grading and to discuss an approach for urban land grading regarding to the urban planning factors. Method of multi-factor synthetic evaluation is employed to model the potential land values and to quantify the impacts of urban planning on land grade. Based on the model result, a set of urban planning factors is refined for urban land grading. The results indicate that urban planning has significant effects on the spatial distribution and variation tendency of urban land values in terms of the urban dimensional distribution and constructions; the technical roadmap taking account of urban planning factors may not only overcomes the limitations of traditional urban land grading, but also expand the technical framework of national regulations. The paper uses a case study of commercial land grading in Wuhan city to demonstrate the validity of the technical roadmap.
