摘要:
开放空间是城市更新的重要抓手,既提供复合功 能、产生综合价值,又促进公众参与,带动周围环境持续自主 更新,从而产生事半功倍的改造提质效果。为充分发挥这项优 势,引入城市触媒理论,使用多源数据和多种方法,从动力、 空间和时间维度建立量化评价体系,对全面反映综合价值和外 部效应的城市开放空间景观触媒效应开展实时、跨尺度、可持 续的评价研究,并以重庆市为例进行实证分析。结果表明,该 评价体系从发展动力、实质性成效和可持续潜力等角度综合揭 示不同尺度下开放空间的现状建设水平和未来发展痛点,其应 用可为以开放空间为架构的城市更新模式提供决策依据。

Quantitative Assessment of Landscape CatalyticEffect of Urban Open Space: A Case Study ofChongqing City
WANG Ziming,ZHU Jie
Abstract:
Open space is vital to urban renewal, providing multiple functions and generating plural values, while promoting spontaneous public participation and driving the surroundings to continuous autonomous renewal, thus producing twice the result with half the effort. To give full play to this advantage, this paper introduces the urban catalyst theory, uses multi-source data and multiple methods to measure the comprehensive performance of open space in terms of landscape catalytic effect, establishes a quantitative assessment system of open space landscape catalytic effect in dynamic, space, and time dimensions, and conducts an empirical study in Chongqing, China. The results show that the assessment system thoroughly reveals the current service level and future development problems of open space at different scales from the perspectives of development dynamics, substantial effectiveness, and sustainability, and its application provides a decision basis for urban renewal approaches using open space as a structure.
Key words:  landscape architecture  open space  catalytic effect  quantitative assessment system  multi-source data  multiple methods
