基于可达性的公园绿地选址设计——以邯郸市主城区为例
Site Selection and Design of Parks and Green Spaces Based on Accessibility—The Case of Handan Main Urban Area

可达性是衡量居民能否便捷地享受公园绿地的重要标准。本文以邯郸市主城区为研究范围，将多源数据纳入高斯两步移动搜索法，计算居民到公园绿地的可达性；以局部莫兰指数识别可达性薄弱地区。结果表明：邯郸市公园绿地可达性空间分布不均衡，形成城区中心与西南两个圈层递减区域；可达性低值聚类区域位于城区北部与正南侧，是公园绿地选址设计应重点关注的地区。研究结果可精准识别公园绿地短缺区域，为城市公园绿地的选址设计提供一定的科学建议及参考。
Accessibility is an important criterion to measure whether residents can enjoy park green space conveniently. This paper takes the main urban area of Handan City as the research scope, and incorporates multi-source data into the Gaussian two-step moving search method to calculate the accessibility of residents to parks and green spaces; and identifies the weak areas of acces-sibility with the local Moran index. The results show that the spatial distribution of the accessibility of parks and green spaces in Handan is not balanced, forming two decreasing areas in the centre and south-west of the urban area; the areas with low accessibility clusters are located in the north and south of the urban area, which are the areas that should be paid attention to for the design of parks and green spaces. The results of the study can accurately identify the shortage areas of park green space and provide certain scientific suggestions and references for the site selection and design of urban park green space.
