Although Open Space Ratio is a critical control in the Development Approval process, there are no ultraviolet radiation (UVR) protection guidelines for urban parks. This study explores key strategies for shade provision in children's play areas in urban parks, aiming to promote sun-safe play environments against alarming skin cancer trends. The literature review identified primary issues affecting UVR exposure in public venues, and the research comprises a shade audit of Beaton Park in Dalkeith. The methods involved using virtual park modeling and Shadow Analysis simulations to generate the daily average number of hours in shade for each month. Our recommendations based on this analysis are (a) a minimum canopy cover representing 50% of the entire ground cover; (b) a minimum diameter for a shade (umbrella) of about 2.5 times the diameter of the table; and (c) an ideal umbrella height of 90 cm from the table surface. This research proposes a potential nexus between landscape design and a UVR protection framework for child-friendly Sun-safe Zones (SsZ).
尽管开敞空间比率是开发审批过程中的一个关键控制因素，但城市公园并没有针对紫外线辐射 (UVR) 的保护指南。本研究探讨了在城市公园的儿童游乐区提供遮荫的关键策略，旨在针对令人担忧的皮肤癌趋势，推广安全的阳光游乐环境。文献回顾确定了影响公共场所有关 UVR 暴露的主要问题，本研究包括对达基特的比顿公园进行遮荫审计。所采用的方法包括使用虚拟公园建模和阴影分析模拟，以生成每个月的阴影中的小时数的日平均值。根据此分析的建议是：(a) 树冠覆盖率最低为整个地面覆盖面积的 50%；(b) 遮荫（伞）的最小直径约为桌子直径的 2.5 倍；和 (c) 理想的伞高度为离桌子表面 90 厘米。本研究提出了景观设计与儿童友好型防晒安全区 (SsZ) 的 UVR 保护框架之间的潜在联系。
