基于Depthmap的城市滨水空间优化研究——以兰州市滨水公园为例

Research on Optimization of Urban Waterfront Space Based on Depthmap:A Case Study of Lanzhou Waterfront Park

随着近年来滨水区的扩建与改造,城市滨水空间使用效率及组织方式已成为衡量滨水区发展活力的重要指标。研究以兰州市马拉松主题城市滨水公园为例,利用Depthmap建立空间关系模型,并结合实地调研数据对相关测算值进行对比研究,通过分析验证了空间组织对空间使用者的吸引程度和使用效率。结果表明,兰州市马拉松主题城市滨水公园中景观空间节点的集成度较低;使用率较高的节点多为具有连接性及多用途功能性的广场开放空间;带状分布的滨水空间节点相关性较差,层次较不分明。基于此提出相关优化策略,并对未来滨水空间的发展予以数据化的理论支撑。

The utilization and organization mode of urban waterfront space grow into an important index to measure the development vitality of waterfront owing to the expansion and transformation of waterfront in recent years.Taking a city waterfront park,Marathon Theme,in Lanzhou as an example,the comparative research is conducted against relevant measured values by establishing a spatial relationship model,and considering the field survey data.Through the analysis,the attraction and utilization of spatial organization to space users are verified.As revealed by the results,the integration of landscape spatial nodes in the waterfront park of Marathon Theme maintains at a low level.The nodes with high utilization rate are usually square open spaces with connectivity and multi-purpose functionality.The correlation of waterfront spatial nodes with banded distribution is low and the boundary is not clear.In view of this,optimization strategies are put forward,and data-based theoretical support for the development of waterfront space in the future is provided either.
