气候变化背景下桂东地区旱涝变化特征分析
Analysis of drought and flood characteristics of eastern Guangxi under the background of climate change
摘要
Abstract
Based on the Z index of precipitation and dry-wet index Si, the annual mean temperature and precipitation data of 9 stations from 1965 to 2013 in eastern Guangxi were analyzed. The conclusion is that in the past 49 years, the degree of drought has increased significantly in eastern Guangxi and the south is 4a more than the north in drought years; there are oscillation periods of 18a, 13a, 6a, 4a, and 2A scales, additionally, from the large-scale oscillation period, the eastern Guangxi has entered a new flood period from 2012. In the study of drought and flood characteristics in eastern Guangxi, the Si index is more advantageous than the Z index and our research results can provide a guide for application.关键词
