本研究通过分析哈尔的小型绿地来解决城市绿地访问的不平衡问题. 它提出了一个多功能网络,以加强环境正义和实现可持续发展目标.
科学领域:
- 城市规划与环境科学
- 生态系统服务和环境正义
背景情况:
- 公平获得城市绿色空间对于环境正义至关重要,与联合国可持续发展目标 (SDGs) 保持一致.
- 从生态系统服务的角度来看,对小型城市绿地及其多功能性的研究是有限的.
研究的目的:
- 分析哈尔城市建筑区绿地供需情况.
- 评估小城市绿地对生态和社会利益的多功能性.
- 构建一个多功能和高效的小型城市绿地网络.
主要方法:
- 分析层次过程 (AHP) 用于分类绿色空间供需.
- 分析功能定位的最小累积阻力和感兴趣点 (POI).
- 绿色空间优先级和定位的多标准决策模型.
主要成果:
- 发现了显著的不平衡:30.17%的严重和48.50%的中等绿色空间不匹配.
- 为五种类型的领域提出了指导方针:集中开发 (16.94%),备份开发 (14.31%),维护 (61.51%),保护 (3.02%) 和优化 (4.22%).
- 一个277.60公里的多功能小型城市绿地网络被提议.
结论:
- 该研究提供了一个框架,以加强城市建筑区的绿色空间公平性.
- 调查结果为决策者和城市规划者提供了关于开发多功能绿色网络的有价值的见解.
- 这种方法可以作为一个模型,在包括发展中国家在内的各种城市环境中实现绿色空间公平.
