达坂城地区1964—2008年蒸发量变化特征分析
Analysis of Evaporation Variatiom Features in Dabancheng Region during 1964-2008
摘要
Abstract
By using the actually observed data on evaporating capacity at Dabancheng weather station of Urumqi from 1964 to 2008,the Variation features of evaporating capacity in Dabancheng and corresponding influential factors were analyzed.The results indicated that the annual,quarterly and monthly evaporating capacities at Dabancheng revealed a declining trend.The annual evaporating capacity was decreasing at a tendency rate of 179.7mm/10a.The declining tendency was mainly happened in summer and spring,and the evaporating capacity decreased the most in May.The influence factors of evaporating capacity were sunshine,temperature,relative humidity,among which evaporating capacity showed positive correlation with wind speed,and negative correlation with sunshine,temperature and relative humidity.The constant decreasing wind speed and increasing relative humidity year by year were the important reasons for the declining evaporating capacity in this region.The increasing tendency of temperature and drought index analysis alsohowed a warm-wet trend signal in Dabancheng region.关键词
