英文摘要	In this paper, the variability of daily temperature in the Yangtze River Delta (YRD) for the period 1958-2007 was investigated by selecting three typical temperature variables (daily minimum, mean and maximum temperatures) and the diurnal temperature range (DTR). Three variability patterns of daily mean temperature and two variability patterns of daily minimum and maximum temperatures were first classed, and then statistical properties of three temperature variables in 1958-1985 and 1986-2007 were analyzed. After that, temporal trends of three temperature variables and DTR were detected. Finally, the impacts of urbanization on the variability of daily temperature were investigated. Results indicate that: (1) daily mean temperature shows more complex variability than daily minimum and maximum temperatures; (2) in 1986-2007 three temperature variables have bigger mean values but smaller Cv (coefficient of variance) values, and are more close to normal probability distribution; (3) three temperature variables show positive trends in 1986-2007, and the increase of daily mean temperature is more due to the increase of daily minimum temperature in the northern YRD but due to daily maximum temperature in the mid and southern YRD; (4) in the mid and southern YRD, daily maximum temperature has bigger increasing magnitude than daily minimum temperature in 1986-2007, causing positive trend of DTR; and (5) rapid urbanization causes normal distribution of three temperature variables, and notably increasing magnitude of daily temperature and DTR in 1986-2007 at the lower reaches of the Yangtze River and the Hangzhou Bay. 2012 Elsevier B.V.
