摘　　要：如何将高密度建成环境内具有一定生境特征的绿色空间转化为城市公园,是集约利用城市空间、平衡空间约束和需求增长、提升人居环境的关键。以成都市青羊区为例,设定现状公园、修正后公园和优化后公园3种情景,构建基于生态供给和社会支撑两个维度,数量、质量和可达性3个方面的评估框架,展开对比性评估和耦合协调度分析。结果表明:现状公园在生态供给维度上量、质失均,社会支撑维度上均衡性和公平性不足,呈现出失调衰退的协调发展特征;将全域范围内具有一定生境特征的绿色空间转化为城市公园,能有效提升城市公园体系的生态供给和社会支撑特征,并显著优化耦合协调特征。因此,为有效优化城市公园及体系,需兼顾绿色空间的供给潜力,在提升现状绿色空间多维供给水平基础上,兼顾生态特征按需配置进行公园建设,并辅以精细管养耦合公园参与的治理管控模式。How to transform green spaces with certain habitat characteristics in high-density built environments into urban parks is the key to intensively utilizing limited urban space,balancing spatial constraints and demand growth,and improving high-quality living environments.With Qingyang District in Chengdu City as the study case,this study sets three scenarios of current parks,modified parks,and optimized parks,to construct an evaluation framework based on the two dimensions of ecological supply and social support and the three aspects of quantity,quality,and accessibility.Then comparative evaluation and coupling coordination analysis are conducted.The research results show that the current parks exhibit uneven quantity and quality in ecological supply,insufficient balance and equality in social support,and a imbalanced and declined coordination of development.To effectively optimize urban park and its systems,it is necessary to take into account the supply potential of green spaces.On the basis of improving the multidimensional supply level of current green spaces,park construction should be carried out according to ecological characteristics and needs,supplemented by a governance model that involves fine management coupled with park participation.
