摘要
Abstract
The data for this study were collected at the weather station of Guide,Qinghai Province,including average daily temperatures of every day,monthly precipitation,and the daily highest and lowest temperatures from 1961 to 2010.According to these data,trends of atmospheric temperatures,precipitation and the daily highest and lowest temperatures over the last 50 years were analyzed,and the years of abrupt changes were checked.We judged drought or waterlog degrees from concurrent precipitation,so as to compare the years of drought or waterlog disasters and their ratios before and after the abrupt changes.The results showed that drought and waterlog disasters became more frequent over the last 50 years.The results of Markovian analysis indicated that waterlog disasters would be in greater probabilities in 5 years from 2011 to 2015.关键词
