绿色空间最近因城市可持续性效益而得到广泛认可，并在可持续发展目标中被提及。本文旨在解决知识差距的指标用于评估绿色空间的城市可持续性在北极使用的纳德姆，俄罗斯是说明紧凑的城市在苏联时期建造的一个系统ofmicrorayons的例子。国际组织实施的绿色空间评估的不同指标进行了比较，在俄罗斯使用的指标。利用极高分辨率的WorldView-3卫星图像和开放源数据，高精度地估计了绿色空间的数量和质量。除了传统上使用的人均绿色空间份额指标，步行距离内的公共空间的份额，以评估绿色空间的可用性和可达性，本文建议考虑到治理，分布和组成的重要性，使用历史遗产，市政预算分配绿色空间维护和归一化差异植被指数值的分析。与其他城市和各国相比，这种详细的观点可以丰富关于绿色空间作为地方和全球一级复原力来源的讨论。
Green spaces have recently received wide acknowledgement for urban sustainability benefits and are mentioned in the Sustainable Development Goals SDGs Target 11.7. The article aims to address the knowledge gap on indicators used for assessment of green spaces for urban sustainability in the Arctic using an example of Nadym, Russia which is illustrative of compact cities built during the Soviet time using a system ofmicrorayons. Different indicators implemented by international organizations for assessment of green spaces are compared with indicators used in Russia. Utilizing very high-resolution WorldView-3 satellite image and open source data, the quantity and quality of green spaces are estimated with high accuracy. In addition to traditionally used indicators of share of green space per capita, share of public spaces for common use within walking distance to assess availability and accessibility of green spaces, the paper suggests importance of taking into account governance, distribution, and composition using analysis of historic legacies, municipal budget allocation for green space maintenance, and Normalized Difference Vegetation Index values. Such detailed view can enrich discussions about green spaces as sources for resilience both at the local and global levels, in comparison with other cities and across countries.
