| 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. |
