三峡库区香溪河流域近20年气候趋势分析
Climate Change Trend Analysis of Xiangxi River Basin of Three Gorges Reservoir Region in Recent 20 Years
摘要
Abstract
Based on meteorological data from Xingshan weather station from 1990 to 2009, which is located at Xiangxi River Basin of Three Gorges Reservoir region, the change tendency of precipitation, air temperature, humidity, wind speed and sunshine duration (solar radiation) in this region was examined using method of Mann-Kendall test. The results show that; Over the past 20 years, the increase of precipitation was not significant (12 mm/10 a) but with apparent inter-annual fluctuations; precipitation in spring and summer was increasing, while fall and winter was decreasing; in the context of global warming climate, the air temperature in this region has increased gradually, the average temperature increase is 0. 3 ℃/10a; the mean minimum increase is 0. 19℃/10a and the maximum increase is 0. 4℃/10a (significant); wind speed decreased firstly and then increased; during 1990 - 2002 wind speed decreased (0. 1 m/s/10a); then since 2003 increased significantly (0. 2 m/s/l0a); humidity was decreasing and monthly evaporation capacity was positively correlated to sunshine duration, while the overall annual tendency presented a negatively correlation.关键词
