摘　　要：为协调公园绿地社交服务潜力供需关系,文章以西安市12个公园为例,基于公园环境特征及参观者的行为特征等数据,采用因子分析、熵值法确定公园绿地社交空间潜力和需求潜力(行为类、属性类)的测度模型,然后利用耦合协调模型分析两者的供需协调度,并确定每种协调关系的环境优化路径。结果表明:1)公园绿地因环境、规模及服务群体的差异,其社交空间潜力及行为类需求潜力存在明显变化。2)基于公园社交空间潜力与需求潜力的协调度将公园分为4种类型:供需协调、供给与行为类需求失调、供给与属性类需求失调及供需失调。3)明确景观休憩场所的兼容改造、场地设计、区位环境的协同升级、个人交通可达性和非景观类活动设施的完备性提升是改善不同类型公园绿地供需不协调的有效策略。综上可知,依据居民社交需求潜力特征,调整完善公园绿地的多功能设施供给及与区位环境的协调程度,是实现公园绿地社交潜力供需匹配的核心。To coordinate the supply-demand relationship of social interaction potential in park green spaces,the paper takes 12 parks in Xi'an to develop the measurement model for spatial potential and demand potential(behavior-oriented and attribute-oriented)of park green spaces in social interaction by using factor analysis and entropy value approach based on the data such as park environmental features and visitors'behavioral characteristics.Then the coupling coordination model is used to analyze the supply-demand coordination degree and then to determine the environment optimization path for each coordination relationship.The results show that:1)Park green spaces have significantly varied social spatial potential and behavior-oriented demand potential because of their differences in environment,scale and groups served;2)Parks are classified into four types based on the coordination between space potential and demand potential of parks,including supply-demand coordination,mismatching between supply and behavior-oriented demand,mismatching between supply and attribute-oriented demand,and supply-demand mismatch;and 3)Identify that the strategies to improve the mismatching between the supply and the demand of various park green spaces are compatible renovation of recreational landscape spaces,site design,synergistic upgrading of location environment,accessibility of personal transportation and facility improvement for non-landscape-focused activities.In conclusion,the key to achieving the matching of supply and demand of social potential in parks is improving the the supply of multi-functional facilities in parks and the level of coordination between parks and its coordination with the location environment in accordance with the features of residents'potentials in social demand.
