【摘要】：当前城市高速增长,土地资源稀缺,同时伴随高速城市化往往出现低效率的土地使用。紧凑与多样是未来城市发展的重要方向之一,这已经得到学界的普遍认同。本文在紧凑城市的理论基础上,着眼于城市用地紧凑度与多样性的研究。用地,是城市物质空间建立的基础。用地的紧凑与多样,是衡量土地集约利用的重要标准,也是现代城市可持续发展的目标之一。本文通过对不同城市(北京、天津、上海)、不同区位(城市中心区、过渡区、边缘区)、不同尺度(3km*3km、1km*1km、500m*500m)的用地样本进行量化测算与统计分析,归纳用地紧凑度与用地多样性在城市空间分布上的一般规律,论证用地紧凑度与用地多样性的正相关关系,并分析其在不同区位及不同尺度下相关性的变化趋势。在此基础上,文章在多尺度(片区、社区、街区尺度)多维度(水平、垂直、时间维度)视角下研究城市用地紧凑度与多样性建设模式。之后,以扬中市西城区控制性详细规划为例,综合考虑多尺度多维度,总结出规划实践中相应的规划策略,对规划前后及不同方案的用地布局进行量化,佐证文章提出的规划策略对于改善用地紧凑度与多样性的可行性与有效性。
[Abstract]:At present, with the rapid growth of cities and the scarcity of land resources, low-efficiency land use often occurs along with high-speed urbanization.Compactness and diversity is one of the important directions of urban development in the future, which has been generally accepted by academic circles.Based on the theory of compact city, this paper focuses on the study of compact degree and diversity of urban land.Land use is the foundation of urban material space.The compact and diversity of land use is an important standard to measure the intensive use of land, and also one of the goals of sustainable development of modern cities.This paper summarizes the general law of land compactness and land diversity in urban spatial distribution, demonstrates the positive correlation between land compactness and land diversity, and analyzes the changing trend of the correlation between land compactness and land diversity in different location and scale.On this basis, the paper studies the construction model of urban land compactness and diversity from the perspective of multi-scale (area, community, block scale) multi-dimension (horizontal, vertical, time dimension).Then, taking the controlled detailed planning of Xicheng District of Yangzhong City as an example, considering the multi-scale and multi-dimension, the paper summarizes the corresponding planning strategies in planning practice, and quantifies the land use layout before and after planning and different schemes.The proposed planning strategy is feasible and effective to improve land compactness and diversity.
