摘要
【目的】以分析北京核心区口袋公园的分布特征为主要目的。【方法】采用矢量数据整理与ArcGIS空间分析相结合的研究方法,以2018年北京市遥感影像图(坐标系为GCS_WGS_1984)为基础,利用ArcGIS软件对北京核心区口袋公园进行矢量化处理,得到2018年北京核心区口袋公园地理数据库。基于数据库进行空间统计分析,对北京核心区口袋公园分布特征做出定量、客观的评价。【结果】北京核心区口袋公园面积整体偏小,平均面积为0.22 hm^(2),具有一定的绿化占比;分布模式呈聚类分布,二环内口袋公园聚类程度比二三环之间更高;分布密度高,具有多个散落的分布重心。【结论】提出目前北京核心区口袋公园布局建设中存在的问题及改善建议,希望对北京核心区以及其他城市中心城区口袋公园建设和旧城更新提供理论参考。
【Objective】The main purpose is to analyze the distribution characteristics of pocket parks in the core area of Beijing.【Methods】This study used a combination of vector data collation and ArcGIS spatial analysis.Based on the remote sensing image map of Beijing in 2018(the coordinate system is GCS_WGS_1984),the ArcGIS software was used to vectorize the pocket parks in the core area of Beijing to obtain the geodatabase of pocket parks in the core area of Beijing in 2018.Based on the spatial statistical analysis of the database,a quantitative and objective evaluation of the distribution characteristics of pocket parks in the core area of Beijing is made.【Results】The overall area of pocket parks in the core area of Beijing is relatively small,with an average area of 0.22 hm^(2),with a certain proportion of greening;the distribution pattern is clustered,and the degree of clustering of pocket parks in the second ring is higher than between the second and third rings;High distribution density,with multiple scattered distribution centers of gravity.【Conclusions】The problems and improvement suggestions in the construction of pocket parks in the core area of Beijing are proposed.It is hoped to provide theoretical reference for the construction of pocket parks and the renewal of old cities in the core areas of Beijing and other urban centers.
