基于干旱K指数的阿勒泰地区夏旱风险区划
Risk Zone of Summer Drought in Altay Area Based on Drought K Index
摘要
Abstract
Using the monthly average temperature and precipitation data that observed by seven weather stations in Altay area from June to August, from 1981 to 2010. The drought index, K , is determined firstly by calculating the potential evaporation through Thomthwaite method, the risk of the summer drought in Altay area were discussed and evaluated using the variation coefficient, the risk probability and risk index of the drought index (K). The results show that the risk of the summer drought was high in Altay. The probability of precipitation less than normal in summer was about 80% and the probability of serious drought was 22%~36%. The results of the comprehensive risk division show that the high possibility of summer drought concentrated in the northern and middle easthern regions in Altay area, while the probability of risk decreased from the northern to southern Altay area.关键词
