国内外城市绿色空间遮阳标准比较研究

Research on Comparison of Domestic and Foreign Shading Standards of Urban Green Space

标准化能将理论研究成果转化为实践导则,更科学地指导设计。目前,中国风景园林领域热环境设计专项标准暂缺,但在其他国家和相关行业已出台了多项涉及城市绿色空间相关热环境标准,其中遮阳作为最主要的降温方式,相关内容在所有标准中占了较大比重。在归纳了国内外主要热环境遮阳标准的基础上,对各自的评价方式、单项指标异同进行比较,分析存在差异的主要原因是气候地理、社会背景、发展程度等条件不同,并从中得出我国同类标准制定研究时,宜丰富指标体系、提升数据可获得性、采用开放评估方式,并保证标准周期性与时效性,以期为我国风景园林行业热环境设计专项标准的制定研究提供参考。

Standardization can help designing more scientifically,with theoretical research knowledge transformed into practical guidelines.Heretofore,there is no thermal environment design standard in the field of Landscape Architecture in China.However,some other countries and related fields have issued some important thermal environment standards.Shading,as a cooling method,is the very important part in all these standards.Based on comparing the evaluation,indicators,and constitutor of the main thermal environment shading standards at home and abroad,this paper concludes that the differences are due to different conditions such as climate,geography,social context,and development phases,and suggests that enrich the index system,improve the availability of data,adopt transparent evaluation methods,and consideration of the periodicity and timeliness of standards.This research aims to provide experiences for developing thermal environment design standards in the field of Landscape Architecture in China.
