重庆合川近28a蒸发特征分析
|
摘要
利用合川区1980—2007年小型蒸发皿蒸发量资料,分析了合川区蒸发量的变化特征及其影响变化的原因。结果表明:合川年、季和月蒸发量均存在明显的上升趋势,影响蒸发量变化的因子有风速、日照、相对湿度、温度、气压、水汽压、降水等,并对影响因子与蒸发的关系进行相关分析。
Evaporation data from small-sized evaporating dish during 1980—2007 in Hechuan district of Chongqing have been used to analyze variaton characterstrics and their reasons of evaporation capacity.The results showed there is an tendency of inereasing yearly,seasonial and monthly evaporation capacities.The factors which influence variation of evaporation capacity include wind velocity,sun shine,relative humidity,temperature,pressure,vapor pressure,precipitation and so on.The relationships between influence factors and evaporation have been analyzed by simple and multiple correlations and meteorological prediction model of influencing evaporation has been found out by stepwise regression.
