Abstract Understanding preferences for urban green infrastructure (UGI) and the factors responsible for these are very important for adequate provision and effective management of these vital components of the urban environment. There are however very few studies that provide insight into residents’ preferences for UGI in sub-Saharan Africa. The aim of this study was to examine residents’ preferences for the different forms of UGI with green, tree, water and other features and the factors that influence these in Lagos Metropolis, Nigeria. The data were obtained via a questionnaire survey of 1560 participants in the study area and analysed using descriptive statistics, Mann-Whitney U and Kruskal Wallis tests and multiple regression analysis. The results indicate that the participants generally showed more preferences for UGI with green features including green corridors, lawns, sports fields, parks and gardens than others. Variation in the participants’ preferences for UGI was mainly due to differences in their local government area of residence. Nevertheless, the four top determinants of participants’ preferences for the different forms of UGI were the environmental and health benefits and quality of UGI as well as the respondents’ involvement in pro-green infrastructure activities in their neighbourhoods. The study conclude that urban planners should focus on strategies that maximise the environmental and health benefits and quality of green infrastructure and foster citizens’ participation in the development and management of UGI in cities in Nigeria and others countries in sub-Saharan Africa.

尼日利亚居民对城市绿色基础设施偏好的决定因素：来自拉各斯大都会的证据

摘要 了解对城市绿色基础设施 (UGI) 的偏好以及导致这些偏好的因素对于充分提供和有效管理城市环境的这些重要组成部分非常重要。然而，很少有研究深入了解撒哈拉以南非洲居民对 UGI 的偏好。本研究的目的是检查尼日利亚拉各斯大都会居民对具有绿色、树木、水和其他特征的不同形式 UGI 的偏好以及影响这些的因素。数据是通过对研究区域 1560 名参与者的问卷调查获得的，并使用描述性统计、Mann-Whitney U 和 Kruskal Wallis 检验以及多元回归分析进行分析。结果表明，与其他人相比，参与者普遍对具有绿色特征的 UGI 表现出更多的偏好，包括绿色走廊、草坪、运动场、公园和花园。参与者对 UGI 偏好的差异主要是由于他们当地政府居住地区的差异。尽管如此，参与者对不同形式 UGI 的偏好的四个主要决定因素是 UGI 的环境和健康效益和质量，以及受访者在其社区参与支持绿色基础设施的活动。
