During past decades, much progress has been made to elucidate the relationship between the quantity of urban green space and crimes, but less is known about how their spatial distribution is associated with crimes. Therefore, this study aims to understand how the composition and configuration of urban green space are related to crimes in metropolitan cities in the United States. Our study performed landscape analysis using 756 census tracts for violent crimes and non-violent crimes in Chicago from 2017 to 2021 while controlling socioeconomic status. Spatial lag models showed that tree canopies were negatively associated with crime rates, while grass areas were positively associated with crime rates. In terms of the spatial distribution, there were more crime incidents in irregularly shaped green spaces compared to reguraraly shaped green spaces. On the contrary, disconnected tree canopies were more likely to have lower crime rates. Aggregated (i.e., a single large) also tended to have less crime rates. The results of our study provide some evidence of the role of the spatial distribution of urban green space on crimes and shed light on the ways to reduce crimes through effective urban green space planning

芝加哥城市绿地的空间分布与犯罪相关吗？

在过去的几十年中，在阐明城市绿地数量与犯罪之间的关系方面已经取得了很大进展，但对其空间分布与犯罪之间的关系却知之甚少。因此，本研究旨在了解美国大都市的城市绿地的构成和配置与犯罪之间的关系。我们的研究使用 2017 年至 2021 年芝加哥 756 个人口普查区的暴力犯罪和非暴力犯罪情况进行景观分析，同时控制社会经济状况。空间滞后模型显示，树冠与犯罪率呈负相关，而草地面积与犯罪率呈正相关。从空间分布来看，不规则绿地犯罪事件多于规则绿地。相反，断开的树冠更有可能降低犯罪率。聚合（即单一大）的犯罪率也往往较低。我们的研究结果提供了城市绿地空间分布对犯罪的作用的一些证据，并揭示了通过有效的城市绿地规划减少犯罪的方法
