珠江上游流域近55年气温变化特征分析
Analysis on character of temperature variation in upstream of Pearl River basin during 55 years
摘要
Abstract
Based on linear regression, Mann-Kendall test and wavelet analysis methods, the temperature series from 1959 to 2008 in the upstream of Pearl River basin were researched. The results indicated that; ①during recent 55 years, the annual temperature presents a significantly upward trend. The temperature rising obviously areas focuses on Hongshui River, Liujiang River, Guijiang River, Hejiang River, Qianxunjiang River, downstream of Wuzhou and North River basin. In addition, the annual temperature exhibits 3,7, 17 and 43 year periods. ②As for seasonal temperature, the summer and autumn temperatures demonstrate a significantly upward trend, while there is an insignificantly upward trend in spring and winter. Generally, seasonal temperature periods are nearly as same as annual temperature, which exist more or less 3,7, 18 and 40 year periods. The results will play an important significance in the climate prediction of Pearl River basin.关键词
