"In this study the author seeks to find whether changes in urban vegetation can be linked to urban social changes by using Detroit [Michigan] as a case study. Demographic trends in Detroit are analyzed in light of the increasing greenness in the city detected by recent satellite images. Robust relationships between greenness change and demographic factors associated with urban decay (population decline, an increase in poverty level, and an increase in vacant units) are found.... It is concluded that vegetation trends could be used as indicators of urban socioeconomic changes. A vegetation-based urban environmental quality index could therefore be developed to monitor physical and social changes in the cities."

城市植被变化是城市人口趋势的指标：底特律为例。

“在这项研究中，作者试图以底特律[Michigan]为例研究是否可以将城市植被的变化与城市社会变化联系起来。鉴于最近在底特律发生的绿色变化，分析了底特律的人口趋势发现绿色变化与人口统计因素之间的稳固关系，这些因素与城市衰落有关（人口减少，贫困水平增加和空置单位增加）....结论是，植被趋势可以用作指示城市的社会经济变化。因此，可以制定以植被为基础的城市环境质量指数，以监测城市的自然和社会变化。”
