Informal green spaces (IGS) are the overlooked and unplanned green spaces in our cities. They have been shown provide a potentially important social and ecological green space asset through contributing to ecological habitat and connectivity, as well as green space accessibility for urban residents. Despite their potential value to urban social-ecological systems, IGS are often overlooked and forgotten in urban planning policy. However, before we can think about how best to govern these spaces, we must first know where they are. This paper proposes a method to spatially locate IGS in a practical and resource sensitive way. We outline a method that uses an overlay analysis of open government data to map IGS at a high resolution and at a landscape scale based on key social-ecological characteristics. The method was applied to a case study in the City of Darebin, Melbourne, Australia, and evaluated through an onsite validation process. Results indicate that the method accurately predicted the location of IGS within the urban environment with an accuracy of 83%. This mapping method has several useful applications both within the Melbourne and Australian contexts, as well as potential application globally. These include enabling future research into how IGS contribute to urban social-ecological systems, as well as enabling land use decision makers seeking to better understand the abundance and nature of IGS sites they manage and how they may govern these spaces in a more informed way.

寻找被遗忘的空间：使用社会生态框架绘制澳大利亚墨尔本的非正式绿色空间

非正式绿地（IGS）是我们城市中被忽视和未规划的绿地。事实证明，它们通过促进生态栖息地和连通性以及城市居民的绿色空间可达性，提供了潜在的重要社会和生态绿色空间资产。尽管 IGS 对城市社会生态系统具有潜在价值，但它们在城市规划政策中经常被忽视和遗忘。然而，在我们考虑如何最好地管理这些空间之前，我们必须首先知道它们在哪里。本文提出了一种以实用且资源敏感的方式对 IGS 进行空间定位的方法。我们概述了一种方法，该方法使用开放政府数据的叠加分析，根据关键的社会生态特征以高分辨率和景观比例绘制 IGS 地图。该方法应用于澳大利亚墨尔本戴宾市的案例研究，并通过现场验证过程进行评估。结果表明，该方法准确预测了 IGS 在城市环境中的位置，准确率为 83%。这种绘图方法在墨尔本和澳大利亚都有多种有用的应用，并且在全球范围内都有潜在的应用。这些包括促进未来研究 IGS 如何为城市社会生态系统做出贡献，以及使土地使用决策者能够更好地了解他们管理的 IGS 地点的丰富性和性质，以及他们如何以更明智的方式管理这些空间。
