From a global perspective, this paper firstly analyzes the governance strategies and cooperation mechanisms of urban open green space as responding to climate change in European countries. Then, taking the Central City of Beijing as a case, the paper explores its urban thermal environment, distribution of urban open green space, and climate governance operation based on the specific conditions in China. Further, with the digital technologies of GIS and RS, it analyzes the nature and related governance demands of urban open green space and then divides the Central City of Beijing into four governance zones, following which this paper discusses the climate policy strategies and implementation approaches of each governance zone.展开更多
【目的】随着中国进入后疫情时代,人们对在大型户外空间进行露营、野餐等集体休闲活动愈发热情与向往,构建针对城市综合公园开放共享适宜度的评价体系,可为住房和城乡建设部在全国开展的城市公园绿地开放共享试点工作提供参考。【方法...【目的】随着中国进入后疫情时代,人们对在大型户外空间进行露营、野餐等集体休闲活动愈发热情与向往,构建针对城市综合公园开放共享适宜度的评价体系,可为住房和城乡建设部在全国开展的城市公园绿地开放共享试点工作提供参考。【方法】以北京市中心城区的44个综合公园为例,通过调研量化分析影响综合公园开放共享的主要因素,包括公园可达性、周边兴趣点(point of interest,POI)功能密度、周边POI功能混合度3个外部建成环境指标,以及公园人流量、公园人均绿地空间、可开展活动丰富度3个内部属性指标,并运用熵权TOPSIS模型赋予各指标权重。【结果】综合计算得出各综合公园的开放共享适宜度,其中17个公园适合立即开放共享,22个公园需要延缓开放共享,5个公园暂不适合开放共享。【结论】在多维指标的影响下,公园开放共享适宜度与城市功能分区之间呈现出较强的相关性,公园可达性、公园人均绿地空间2个指标对公园开放共享适宜度影响较大,该结论可为城市公园可持续发展战略的制定提供参考。展开更多
