摘要
研究了湖北省1961～1995年年、季、月时间尺度平均最高气温、最低气温和气温日较差的气候倾向率时空差异．结果表明，在年平均情况下，湖北省大部分地区最高气温有弱降温趋势，最低气温有明显增加趋势，气温日较差有显著减小趋势；还分析了气温日较差减小的三种类型，并指出最高、最低气温的变化趋势与日照百分率及大气相对湿度的变化趋势有关．
?The inclination rate of mean maximum temperature (7'M ), mean mini-mum temperature (Tm) and diurnal temperature range (TD) is calculated in differenttime scales (year, season, month ) from l961 to l995 in Hubei Province. The re-sults show that: Tm. has been increasing significantly in winter and TM has beendecreasing significantly in summer. Yearly average minimum temperature hasbeen increasing while yearly average maximum temperature changes little. This re-sults in very obvlous decreasing trend for 7'I,- The reasons are also analysed in thepaper.
