中文摘要：

商业网点规划是指导和管理城市商业空间发展的法律依据，对实施效果的评估是评价规划和监督执行的重要措施之一。中国已实施的城市规划评估大都以定性评估方法为主，难以保证评估的客观性和科学性。基于长沙市商业网点规划和实地调查数据，从空间布局和业态结构两个方面，应用GIS分析方法，对发展现状与商业网点规划进行比较研究。研究显示：规划与现状存在较大差别，商业网点规划没有充分认识城市空间结构、商业业态的发展特点和空间区位选择机制，未能有效地引导和控制商业和业态空间结构的发展和演变。

英文摘要：

Commercial network planning is an important legal basis to guide and administer urban development of commercial space. Assessment of implementation effect is one of the concrete measures of examining the planning. Most of urban planning assessments in China adopted qualitative methods, which cannot guarantee the objectivity and accuracy of the evaluation to some degree. This paper conducts a comparative study on current development situation and commercial network planning by applying GIS methods from two aspects of the spatial layout and format structure, based on the commercial network planning and survey data of Changsha city. The results are shown as follows. There are large differences between planning and current situation of commercial network. Commercial network planning has not focused on the structure of urban space, the development stage of commercial activities and spatial location selection mechanism, thus failed to effectively promote the commercial spatial structure evolution and development.
