气候舒适度对人居环境和人类活动具有深远影响,相关的评价模型/指数在建筑设计、城市规划、人体健康和旅游发展等领域有着广泛应用。体感分级标准作为气候舒适度评价模型不可或缺的关键环节,对模型效度有着重要的裁量权,也是实践应用中最终的度量衡工具。目前体感分级标准研究和应用中异地套用和局地实测的传统做法,在制定国家尺度普适性标准时遇到较大瓶颈。本文试图提出包含“定级—定名—定点—定宽”等基本环节的“季节锚点法”这一新的体感分级思路,并基于中国1981-2010年间814个基本(基准)气象站点的日值气象数据,以温湿指数和风效指数为例开展了实证研究。研究给出了“暑—热—暖—温—凉—冷—寒”这一针对中国区域的7级体感划分标准,并具体给出了温湿指数和风效指数在各体感等级上的阈值区间,进而在此基础计算评价了中国气候舒适期和不舒适期的时间长短、空间格局及其历时变化,得到一些有益发现。未来的研究可以进一步就细分人群、测试模型和区域差异等方面的体感分级标准开展更多深入探索。

Climatic comfort or human thermal comfort has a far-reaching impact on human settlements and human activities. A number of thermal indexes are widely applied in the fields of architectural design, urban planning, human health, and tourism development. As an indispensable and critical part of climatic comfort assessment, scale of thermal sensation not only greatly affects the validity of a thermal index, but also makes the comparison among different thermal indexes possible. At present, a few traditional scales of thermal sensation are generally used for the climatic comfort assessment in different regions without any localized adjustment. Alternatively, experimental investigation and questionnaire survey are adopted to formulate the scale of thermal sensation for a certain area. Therefore, a new approach named "seasonal anchor method" is proposed in this paper, which includes 4 steps --"grading, naming, anchoring, and projecting". Furthermore, based on the long term daily meteorological data (from 1981 to 2010) from 814 national basic meteorological observing stations throughout China, a case study is carried out. In this study, a 7-level scale of thermal sensation, which includes "torrid, hot, warm, neutral, cool, cold, and frozen", is proposed. Meanwhile, the threshold values of each level of thermal sensation for THI (temperature and humidity indexes) and WEI (wind effect index), which can be adopted as a national standard, are generated. Finally, climate-comfortable period and climate-uncomfortable period in China are evaluated, which brings us some meaningful discoveries.
