Tree Equity Score 2025 - Suburban
收藏资源简介：
This layer displays calculated 2025 Tree Equity Scores for the Suburban Official Plan Transect. The layer was produced using a modified version of the American Forests methodology, where a Tree Canopy Goal was created based on a Transect-level building density calculation. Tree Equity Scores were calculated at the census tract level for all Official Plan designated residential areas within the urban boundary. Canopy cover was calculated using the 2022 Canopy Cover Assessment. The Priority Index was calculated using data from 2021 Census, 2019-2020 Canadian Community Health Survey, and 2022 Landsat thermal band imagery. More information on the methodology used to create the data can be found on the City of Ottawa website. This layer was produced by Climate Change and Resiliency Services, Strategic Initiatives Department, to guide the selection of priority areas for tree planting under the Tree Planting Strategy. Accuracy: Data are complete and there are no known issues. The Tree Equity Score analysis was created using 2021 census data to provide information on socio-economic and demographic data. Census data was combined with urban heat and canopy cover data to produce a Tree Equity Score. The analysis was performed only for urban, residential areas of the census tracts. Results of the analysis have been used to identify and prioritize areas of in need of tree canopy cover.

本图层展示了郊区官方规划样带(Suburban Official Plan Transect)的2025年树木公平评分(Tree Equity Score)计算结果。本图层采用经改良的美国森林协会(American Forests)方法制作，该方法通过样带(Transect)级别的建筑密度计算设定树木覆盖目标。树木公平评分以普查区(census tract)为统计单元，针对城市边界内所有官方规划指定的住宅区开展计算。树冠覆盖率通过2022年树冠覆盖评估数据计算得出。优先指数(Priority Index)则整合2021年加拿大人口普查数据、2019-2020年加拿大社区健康调查(Canadian Community Health Survey)以及2022年Landsat热波段影像数据进行计算。有关本数据集制作方法的详细信息，可访问渥太华市(City of Ottawa)官网查询。本图层由战略倡议部气候变化与韧性服务部门制作，旨在为《树木种植战略》下的优先植树区域遴选提供决策支撑。 数据准确性说明：本数据集完整无缺，暂无已知问题。本次树木公平评分分析采用2021年人口普查数据，以提供社会经济与人口统计相关信息。普查数据结合城市热环境与树冠覆盖数据，生成树木公平评分。本次分析仅覆盖普查区范围内的城市住宅区。分析结果已用于识别并优先确定亟需提升树冠覆盖的区域。 数据归属：本数据由气候变化与韧性服务部门所有。引用来源：美国森林协会方法、2025年Environics Analytics(EA)-2025社区健康报告、加拿大统计局(Statistics Canada)2021年人口普查数据、美国地质调查局(U.S. Geological Survey)数据。 属性说明： CTUID：唯一普查区识别编号 CTNUM：简化版普查区识别编号 NAME：普查区名称 TRANSECT：普查区所属样带 CANCVR：普查区面积占比的树冠覆盖率（百分比） CANGOAL：基于建筑密度计算的样带级目标树冠覆盖率（百分比） CANGAP：样带级目标树冠覆盖率与普查区实际树冠覆盖率的差值（百分比） GAPSCORE：以目标与实际树冠覆盖最大差值归一化后的差值评分 PRIORITY INDEX：针对每个普查区的优先指数，由7项权重均等的社会经济、城市热环境与健康因子组成 TREE EQUITY SCORE：基于GAPSCORE与PRIORITY INDEX计算得出的普查区树木公平评分 PRIORITY AREA：标记该普查区是否被认定为优先区域 备注：普查区样带分类包括：市中心核心区、内城区、外城区、郊区。 联系方式：Nick Stow，自然系统项目经理
