Abstract: Based on the meteorological data during 1953-2004, the characteristics of climate change in Shenzhen in the recent 50 years are studied. The results are summarized as below: the temperatures have increased, with a warming rate of 0.34 ?/10 a; the warming rate is larger in summer and autumn; temperature increase at night is more remarkable. Daily temperature ranges become smaller, particularly in autumn and winter. The lowest temperature shows an increasing trend. Hot days is increasing. Precipitation days, sunshine times and relative humidity are obviously decreasing. These characteristics are more remarkable after 1980s, when Shenzhen started developing rapidly. The results suggest that the effect of urbanization in Shenzhen should be considered in future study of climate change.

Key words: Shenzhen, climate change, warming, urbanization

摘要： 利用对深圳站1953—2004年气象资料分析深圳50多年的气候变化特点。主要表现为气温呈明显上升趋势，增温速率达0.34 ℃/10a，其中夏、秋季增温较大；夜间温度上升较明显；日较差呈下降趋势，秋冬季节下降幅度较大；极端低温上升趋势明显，高温日数也显著增加；年降水天数、日照时数和相对湿度都明显下降。各气象要素在进入20世纪80年代后都有比较明显的变化趋势，这与深圳的城市高速发展时期十分吻合。这说明对深圳气候变化的进一步研究中需要分析城市化的重要影响。
