面向行为尺度的城市绿地格局公平性评价及其优化策略——以深圳市为例

Equity Assessment on Urban Green Space Pattern Based on Human Behavior Scale and Its Optimization Strategy:A Case Study in Shenzhen

应用景观生态学基本概念和理论,提出城市绿地格局公平性概念,探讨面向行为尺度的城市绿地格局公平性评价方法。以深圳市为例,利用ArcGIS中邻域分析方法,对4种情景的绿地格局公平性进行评价,并提出针对性优化策略。研究结果表明:1)深圳市绿地公平性存在明显的空间分异;2)绿地格局的绝对公平性(E)与相对公平性(E*)差异明显,居住用地的配置在一定程度上会影响城市绿地格局的公平性;3)不同行为尺度下的公平性差异明显,出行距离会对城市绿地格局公平性产生影响;4)公平性评价结果可以用于指导绿地格局优化设计,进而为城市绿地系统规划和管理提供参考依据。

Integrating the basic theories of landscape ecology,the concept of equity of urban green space pattern is put forward to explore an equity assessment method oriented on human behavior scale.The authors choose Shenzhen as a case study,using the method of neighborhood analysis on ArcGIS platform,to assess the equity of urban green space pattern in four scenarios and carrying out discussions on its optimization strategy.The results show that： 1） spatial differentiation exists obviously in equity on urban green space in Shenzhen;2） the big differences between absolute equity（E） and relative equity（E＊） on urban green space pattern indicate that the configuration of the residential land could affect the equity of urban green space pattern in some extent;3） the different results under two behavior scales demonstrate that trip distance could impact the equity of urban green space pattern;4） the equity assessment results could be used to guide the optimization of urban green space pattern and provide reference for urban green space system planning and management.
