摘　　要：文章以福州沙滩公园为研究对象,利用泰玛斯TM-213紫外线测光仪测量公园内不同下垫面的紫外辐射强度,检验不同下垫面对紫外线辐射的屏蔽效果,并基于单因素方差分析法识别不同下垫面的紫外线屏蔽效果差异。结果表明,天空直射和地表反射两种情况下的两大类下垫面的紫外线屏蔽效果均存在显著差异。研究结论将对今后优化城市游憩空间的下垫面设计具有重要的参考价值。This paper takes Fuzhou Beach Park as a case to measure the ultraviolet radiation intensity of different underlying surfaces in this park using the TM-213 ultraviolet photometer,to test the shielding effect of the different underlays on ultraviolet radiation.Then it identifies the difference in the shielding effectiveness of the underlying surfaces based on one-way ANOVA method.The results show that there are significant differences in ultraviolet shielding effects between two types of underlying surfaces under the context of the direct sunlight and ground reflection.The research results will have important reference value for optimizing the design of the underlying surface of urban recreation space in the future.
