摘 要：大量关于城市绿地（UGS）的研究表明，设计和管理UGS不仅可以为城市提供社会、环境和经济效益，还可以为城市居民提供心理、身体和生理效益。然而，过去的研究集中在城市地区广泛认可的绿地，如公园、花园和森林。被称为非正式绿地（IGS）的荒地、荒野和未规划的中间地带也可以提供补充绿地。本研究通过解决以下问题，对东京后工业卫星城——市川市的IGS进行了探索：（a）目标区域存在哪些类型的非标准化和非系统化绿地？（b） 目标区域的IGS是如何感知的？（c） IGS是否可以被视为城市的补充绿地？通过系统的土地利用调查，我们确定了市川市的九种IGS类型，占总土地利用的6.35%。一项问卷调查显示，本科生认识到他们的社区存在IGS，感受到多种好处，尤其是街道边缘、未改善的土地和水边作为潜在的补充绿地。我们得出结论，IGS可以作为补充绿地，并讨论如何将IGS整合到绿地规划中，以改善居民福祉。
Abstract: Multitudinous studies about urban green space (UGS) reveal that designed and managed UGS may provide not only social, environmental, and economic benefits for cities, but also mental, physical, and physiological benefits for their residents. However, past studies have focused on widely recognized green spaces in urban areas such as parks, gardens, and forests. Wasteland, wilderness, and unplanned in-between margins, which have been called informal green space (IGS), could provide supplementary green space. This study explores IGS in Ichikawa City, a post-industrial satellite town of Tokyo with scarce UGS, by addressing the following questions: (a) What types of non-standardized and unsystematised green space exist in the target area? (b) How is IGS in the target area perceived? (c) Could IGS be considered supplementary green space for the city? Using a systematic land use survey, we identified nine types of IGS in Ichikawa City that accounted for 6.35% of total land use. A questionnaire survey showed that undergraduate students recognize the existence of IGS in their neighbourhood, perceive multiple benefits and see especially street verges, unimproved land and water verges as potential supplementary green space. We conclude that IGS can serve as a supplementary green space and discuss how IGS might be integrated into green space planning to improve residents’ well-being.
