摘　　要：滨水公园是城市蓝色空间的重要组成部分,其活力的提升对宜居性城市建设具有重要意义。以昆明市24个典型的滨水公园为例,利用手机信令数据分析其不同时段的活力时空特征及影响因素。在已有的研究基础上提出活力峰度和偏度,分析不同时段滨水公园活力的时空分布特征;从服务、交通、景观三个维度利用地理探测器分析滨水公园的活力驱动因子及其交互作用。结果表明:(1)昆明市滨水公园活力时间分布呈现出“早晚低谷,午后高峰”的特征,活力高峰都出现在下午,但工作日的活力高峰较休息日向后推迟;工作日滨水公园活力集聚明显,高峰突出;休息日则高峰分散,活力较为均衡;在空间上活力值围绕滇池呈现“北高南低,东部聚集”的特征。(2)在活力影响因素方面,滨水公园1000m内各类设施的功能混合度是影响不同时段活力的共性因素,此外,工作日500m的交通路网密度以及公交站点数量的影响较为显著,而在休息日与CBD的距离以及水域面积的影响较为显著;滨水公园活力的受到多维度因子共同作用的影响,景观维度的影响因子与其他维度的影响因子交互作用最显著。基于此为进一步提升昆明市滨水公园活力从功能完善、空间协调、设施配置、景观提升角度提出了优化建议。Waterfront parks are an essential part of urban blue spaces.Improving the vitality of waterfront parks is crucial to constructing livable cities.The study analyzed the spatial and temporal features of the vitality of 24 typical waterfront parks in Kunming City in different periods and relevant influencing factors using mobile phone signaling data.Vitality kurtosis and skewness were proposed based on existing studies to analyze spatial and temporal distribution features of the vitality of waterfront parks in different periods.Additionally,the relationship between the built environment of waterfront parks and vitality was discussed in depth,and the spatial and temporal features of vitality were disclosed through a quantitative study.The key influencing factors of service,traffic and landscape as well as their interactions were further analyzed.The results show that:(1)concerning temporal distribution,the vitality of waterfront parks in Kunming is characteristic of a"valley in morning and evening,but peak in afternoon."The vitality peak occurs in the afternoon,but the vitality peak during workdays(after 17:00)is later than on non-workdays(after 15:00).Vitality on all days presents a general trend of steady,rising,and decreasing.The vitality of waterfront parks concentrates obviously on workdays,with prominent peaks.The vitality peak on non-workdays disperses and is relatively balanced.(2)Regarding spatial distribution,the vitality of waterfront parks is characteristic of"high in the north,low in the south and concentrating in east."The east bank areas are close to the main urban area and have high traffic accessibility.Waterfront parks with high vitality mainly focus on the northeast bank areas of Dian Lake.The road network density on the west bank of Dian Lake is low,and the waterfront parks are large in scale.However,the overall comprehensive vitality is relatively low.There is some mismatch between the level scale and the vitality of waterfront parks.(3)The function integration of various facility types within 1,
