摘　　要：区位优势度是衡量一个地区经济、社会发展的重要指标。为加强区域内部资源整合与生产力要素合理配置,区位优势度评价在城乡体系规划中起到日益重要的作用。基于网格思想,建立统一的空间分析评价基础模型,提出以交通网络密度优势度、距交通线路距离优势度、经济影响力优势度作为区位优势度基本指标的评价模型,经济影响力优势度指标是以各城镇GDP数据来计算的,较以往模型中的行政地理区位影响指标更具有合理性。模型计算的每一类指标都可以量化比较,可从不同角度对城镇发展潜力进行量化评价与对比分析。利用GIS强大的空间分析能力实现了环渤海地区区位优势度的综合评价分析。Location advantage value is an important indicator to evaluate regional economy and social development. In order to strengthen the integration of regional internal resources and the rational allocation of production factors, location advantage value evaluation plays an increasingly important role in urban and rural system planning. Based on the idea of grid, to build an integrated base model of spatial analysis and evaluation, proposals were made to take advantage values of traffic network density, distance from transport line and economic influence as location advantage value basic indexes of evaluation model. The advantage value of economic influence here is calculated by GDP data of towns, and it is more reasonable than the influence indicator of administrative geographical area from previous model. Each class index that is calculated by model can be quantitatively compared, and urban development potential can be quantitatively evaluated and compared at a different angel. Finally, the results show that this model better reflects difference of the location advantage value in Areas Surrounding Bohai.
