摘　　要：城市公园是城市中重要的组成部分,研究其可达性可以了解公园服务效能程度。为了研究沈阳市公园的可达性,基于百度地图应用程序接口(application programming interface,API)求取不同交通方式下最短通行时间;基于引力模型,结合人口数据、通行时间计算公园可达性,进一步分析公园时空可达性。结果表明:驾车方式下的公园可达性最高,其次是骑行方式,步行出行方式较低,在考虑环保、低碳等情况下,骑行是首选的出行方式;对于空间可达性,可达性较高的公园主要分布在城中心外围东北方位的区域,而中心城区的公园可达性较低;高可达性的小区人口密度较低,而低可达性区域人口密度较大,公园分布存在一定不足,在未来城市公园规划中,应着重考虑低可达性高人口密度的小区。City parks are important parts of the city and studying their accessibility helps us understand the service efficiency of these parks.In order to study the park accessibility in Shenyang city,the shortest travel time under different traffic modes is calculated based on Baidu map API(application programming interface).Then based on the gravity model,combined with population data and travel time,the accessibility of the park is calculated,and the spatial and temporal accessibility of the park is further analyzed.The results show that:the accessibility of the park is the highest under the driving mode,followed by the cycling mode,and the walking mode is relatively low,and therefore cycling is the preferred travel mode considering the environmental protection and low-carbon situation;for spatial accessibility,the parks with high accessibility are mainly distributed in the northeast of the urban area,while the parks in the city center have low accessibility;the population density in areas with high accessibility is low,but high in areas with low accessibility,due to those deficiencies in park distribution,in the future urban park planning,the residential areas with low accessibility and high population density should be mainly considered.
