城市绿色空间服务绩效评估及影响机制--基于武汉中心城区的案例

City Green Space Service Performance Evaluation and Influence Mechanism:Phenomenon and Planning Implication of Wuhan Central Urban Area

在理论推导绿色空间服务绩效与城市空间结构存在相互关系以及良好服务绩效标准的基础上,以武汉中心城区实证表明了在绿色空间总体供给水平大幅度下降的压力下,多中心结构是一种导向良好服务绩效的理性模式。接着以交叉表统计方法对城市空间要素和绿色空间的关联性和作用机制作出解释。最后,基于武汉研究的发现,提出多中心城市空间组织优化与提高绿色空间服务绩效的规划政策建议。

On the basis of the relationship between city green space service performance and urban spatial structure,firstly,this paper summarizes a good criterion of green space service performance.Secondly,taking Wuhan Central Urban Area as an example,it is verified that under the pressure of the overall supply level of green space dropping significantly,multi-center structure is a rational model to guide good service performance.Thirdly,paper uses cross table statistical method to explain the relationship and mechanism between urban spatial elements and green space.Finally,based on the discovery of Wuhan case,we propose planning policy advices for multi-center urban space optimization and the improvement of green space service performance.
