Industrialization, population growth, and urbanization are all trends driving the explosive growth of the construction industry. Creating buildings to house people and operate industry, together with building infrastructure to provide public services, requires prodigious quantities of energy and materials. Most of these virgin materials are non-renewable, and resource shortages caused by the development of the built environment are becoming increasingly inevitable. The gradually evolved circular economy (CE) is considered a way to ease the depletion of resources by extending service life, increasing efficiency, and converting waste into resources. However, the circularity of construction materials shows heavy regional distinctness due to the difference in spatial contexts in the geographical sense, resulting in the same CE business models (CEBMs) not being adapted to all regions. To optimize resource loops and formulate effective CEBMs, it is essential to understand the relationship between space and CE in the built environment. This paper reviews existing publications to summarize the research trends, examine how spatial features are reflected in the circularity of materials, and identify connections between spatial and CE clues. We found that the majority of contributors in this interdisciplinary field are from countries with middle to high levels of urbanization. Further, the case analysis details the material dynamics in different spatial contexts and links space and material cycles. The results indicate that the spatial characteristics can indeed influence the circularity of materials through varying resource cycling patterns. By utilizing spatial information wisely can help design locally adapted CEBMs and maximize the value chain of construction materials.
工业化、人口增长和城市化都是推动建筑业迅猛发展的趋势。建造房屋供人们居住和工业运营，以及建造基础设施提供公共服务，都需要大量的能源和材料。这些原始材料大多是不可再生的，由于建筑环境的发展，资源短缺变得越来越不可避免。逐渐演变的循环经济（CE）被认为是一种通过延长使用寿命、提高效率和将废物转化为资源来缓解资源枯竭的方法。然而，由于地理意义上的空间背景差异，建筑材料的循环性表现出明显的地域差异，导致相同的循环经济商业模式（CEBMs）不能适应所有地区。为了优化资源循环并制定有效的 CEBMs，了解建筑环境中空间与 CE 的关系至关重要。本文综述了现有文献，总结了研究趋势，考察了空间特征如何反映在材料的循环性中，并确定了空间和 CE 线索之间的联系。我们发现，该跨学科领域的大多数贡献者来自城市化程度中等及以上的国家。此外，案例分析详细说明了不同空间背景下的材料动态，并将空间和材料循环联系起来。结果表明，空间特征确实可以通过不同的资源循环模式来影响材料的循环性。明智地利用空间信息可以帮助设计适合本地的 CEBMs，并最大限度地提高建筑材料的价值链。
