deficit zone experience green building block

Low with deficit zone of experience green at building block level (150m and 2 min walk). The deficit zone is the residential area that represents the inverse of the given range zone. By experience green we mean: - publicly accessible greenery for use without surface restriction: parks, pocket parks, hanging green, fort green, dog walking area, city forest, play forest, cemetery, green playgrounds, publicly accessible building green - agricultural or agricultural green, unless completely inaccessible - natural green, unless completely inaccessible: e.g. Hobokense Polder, Wolvenberg This data layer is updated annually in January, provided that the facility is managed and updated annually by the relevant sector/service. In addition to the spatial distribution of facilities at neighborhood, district and district level, with this fine-meshed building block level, we want to draw attention to the importance of the immediate proximity (two minutes walk) of greenery, square or nature, this in function of climate and against heat stress. Important barriers (water, ring, highway, rail, etc.) and safe crossings for vulnerable road users (tunnels, bridges, pedestrian crossings with traffic lights) are also taken into account here.

本数据集覆盖街区单元（building block level，即150米步行距离或2分钟步行时长）维度，体验型绿地（experience green）匮乏区域占比偏低。其中，匮乏区指与给定范围区呈反向对应的居住区。本数据集对体验型绿地的定义如下：一是无使用场地限制的公共开放绿地，包括公园、口袋公园、立体绿化、要塞绿地、遛狗专区、城市森林、游乐林、墓园、绿色游乐场、公共建筑附属绿地；二是农业用地或农业绿地，完全无法进入的除外；三是自然绿地，完全无法进入的除外，例如霍博肯圩田（Hobokense Polder）、沃尔文山（Wolvenberg）。本数据图层每年1月更新，更新前提为相关主管部门或服务机构需对设施进行年度管理与维护。相较于社区、片区及行政区级别的设施空间分布模式，本数据集通过精细的街区单元尺度，旨在凸显绿地、广场或自然空间在2分钟步行范围内紧邻可达的重要性，以助力气候变化应对与热应激缓解。本次分析还纳入了重要阻隔因素（水域、环城道路、高速公路、铁路等）以及面向弱势道路使用者的安全过街设施（隧道、桥梁、带交通信号灯的人行横道等）。
