摘要

This paper analyzed the data of temperature and precipitation in Turpan and Nantong,in the west and east of China,respectively,during the period of 1961- 2007 by linear growth rate,moving average methods,Mann-Kendall nonparametric and moving T tests. The result indicated that the annual average temperature in Turpan had a linear growth rate of 0. 42 ℃ /10 a,while the annual average temperature in Nantong had a linear tendency of 0. 48 ℃ /10 a. The annual average maximum temperature in Turpan with linear growth rate of 0. 16 ℃ /10 a was lower than 0. 56 ℃ /10 a of Nantong,and the annual average minimum temperature in Turpan with linear growth rate of 0. 86 ℃ /10 a was higher than 0. 70 ℃ /10 a of Nantong. The annual average temperature of Turpan increasing was 7 years earlier than Nantong. The annual average maximum temperature of Turpan increasing was 5 years later than Nantong. The annual average minimum temperature of Turpan increased as same as Nantong in 1986,but the curve showed different process completely. The abrupt change year of average temperature between Turpan and Nantong were same in 1996,and the abrupt change year of average maximum temperature of Turpan was 5 years later than Nantong. For precipitation,Turpan and Nantong had the same trend of increased and decreased. The reason of almost identical trend of temperature and precipitation between Turpan and Nantong may be urbanization and population increasing influencing climate change in a small area.
