摘要
针对高斯两步移动搜索法不满足城市空间精细化治理的客观需求,该文以北京市西城区为例,综合考虑不同公园绿地属性差异,在高斯两步移动搜索法的基础上分别构建公园绿地综合服务能力评价与吸引力评价模型提出阈值可变化方法,解决其固定阈值问题.并对高斯两步移动搜索法和可变阈值的高斯两步移动搜索法进行对比分析.结果表明,该文方法使搜索阈值精细化、动态化,更能精准真实地反映居民日常游览公园绿地的出行实际,对未来城市公园绿地空间的合理规划布局与建设具有良好的参考价值.
Abstract
Aiming at the problem that Gaussian two-step mobile search method can not meet the objective needs of fine governance of urban spaces,taking Xicheng District of Beijing as an example and given the differences of different park green space attributes,the park green space comprehensive service capability evaluation model and attractiveness evaluation model were constructed respectively on the basis of Gaussian two-step mobile search method in this paper,and a threshold variable method was put forward to solve the problem of fixed threshold.A comparative analysis of Gaussian two-step mobile search method and Gaussian two-step mobile search method with variable threshold was studied.The results showed that the proposed method made the search threshold refined and dynamic,which could be more accurately and truly reflect the actual travel of residents visiting park green space,and had reference value for the rational planning,layout and construction of urban park green space in the future.
