中文摘要：

本文根据《翁同琳日记》中关于1868年-1898年季节性换装的记录和北京的器测温度记录，采用相关分析和回归分析方法，探讨了季节性换装的迟早与气候变化的关系。结果表明：①从1868年-1898年年内冷暖变化和季节性换装的平均状况来看，作者的衣冠质地随着温度的季节性变化而改变，但是任意一类衣冠对应的上半年的温度条件均比下半年偏高3℃～5℃，而且春季的换装速率比秋季慢；其中，后者是人对北京地区春季升温速率较秋季降温速率慢的气候特征做出的适应性响应；②从年际波动和变化趋势来看，上半年的变冷（暖）对应于季节性换装日期的推迟（提前），下半年与之相反；1868年～1898年，上半年的季节性换装日期趋于推迟，下半年趋于提前，这是人对北京地区春季和秋季均呈变冷趋势的适应性响应。但是，人类季节性换装对不同时节冷暖变化响应的敏感性存在明显差异，对初春、暮春、秋初、秋末的响应较为敏感，特别是对秋末的响应最为敏感。

英文摘要：

Climate change has impacted human society on many aspects, including the daily life. Seasonal dressing change （SDC） as a main component of daily life has also been influenced obviously. In this paper, dates of several SDC during 1868 - 1898AD about Weng Tonghe are extracted from a private diary named ＂Weng Tonghe Diary＂ ,which was written by Weng Tonghe during 1858 - 1904 AD and edited by Chen Yijie in the later of 20th century. These SDC nearly cover the whole year, from the April to the December. Then, with the monthly mean temperature measured by instruments in the same period, the Pearson Correlation and Linear Regression are employed to investigate the correlation between the date of SDC and climate change. Firstly, the average dates of twenty kinds of SDC are analyzed. It is revealed that the dress with different textures are alternate seasonally with the seasonal wanning/chilling cycle, but the corresponding relationship between dress texture and temperature in the early half of year was different from it in the later half of year. In detail, based on the four kinds of dress with different textures, in the early half of year, fur coat, wadded jacket, shirt, normal silk and Ge Sha （sinker silk） respectively fits in with lower than 12℃, 12℃ - 16℃, 16℃ - 22℃, 22℃ - 26℃ and higher than 26℃ ; however, in the later half of year, these four kinds of dress respectively fits in with lower than 6℃, 6℃ - 14℃, 14℃ - 18℃, 18℃ - 21 ℃ and higher than 21 ℃. In other words, the temperature to which any kind of dress was corresponding in the early half of year was higher 2 ℃ - 3℃ than it in the later half of year. Besides, in the early half of year, it could take about 90 days from fur coat to Ge Sha （a very thin silk） ; however, it only takes about 60 days from Ge Sha to fur coat, in the later half of year. This phdnomenon is the adaptive response to the climate characteristics of Beijing that autumn chilling is more quickly than spring warming. Secondly, on the inter-an
