【摘要】 伴随我国城镇化进程的加快，城市人口规模不断增加、城市建成区迅速拓展，高密度空间的建设成为现代城市空间形态的显著现象。城市空间密度强度的地域分布，在一定程度上反映出城市主体建设区域与活力聚点，是衡量城市空间资源合理利用的重要表现指标。基于形态现象的分布规律，应对城市更新的内在需求，该文以沈阳铁西区核心区为例，通过划分街区单元，以建筑密度、容积率与平均层数来表征城市用地斑块密度特征分布，并探究道路、绿地、服务设施点等因子分布与城市高密度空间分布的相关性，进而通过识别空间问题，探寻形态集聚规律，为城市更新治理的后续开展、合理分配空间资源与营造城市活力触媒，提供研究基础。更多还原

【Abstract】 With the acceleration of our country’s urbanization process, the scale of urban population continues to increase, urban built-up areas are rapidly expanding, and the construction of high-density spaces has become a significant phenomenon in the form of modern urban spaces. To a certain extent the geographical distribution of urban spatial density intensity reflects the main urban construction areas and vitality gathering points,and is an important performance indicator for measuring the rational use of urban spatial resources. Based on the distribution law of morphological phenomena, in response to the inherent needs of urban renewal, we take the core area of Tiexi District in Shenyang as an example. By dividing block units, the characteristic distribution of urban land patch density is characterized by building density, floor area ratio and average number of floors.We also explore the correlation between the distribution of factors such as roads, green spaces, and service facilities and the high-density spatial distribution of cities, and then through identifying spatial problems, we explore the pattern of agglomeration rules, and rationally allocating space resources and creating urban vitality catalysts for the follow-up development of urban renewal governance, so as to provide research foundation.更多还原
