| 摘 要： | 根据抚顺地区3个气象站1995~2004年的气象资料,应用FAO推荐的Penman-Monteith公式计算了10年来每年(5~9月)各月的参考作物需水量ET0,分析了ET0的月际变化和年际变化特征。抚顺地区的ET0月际和年际变化都较大,但ET0的变化趋势十分相似。同时分析了各气象因素对ET0的影响,对清源气象站的年均ET0的影响较大的气象因素是:最高气温(Tmax)、相对湿度(RH)、实测风速(U)以及日照时数(H),其中相对湿度(RH)与ET0呈负相关性;对章党气象站的年均ET0的影响较大的气象因素是:相对湿度(RH)和日照时数(H),其中相对湿度(RH)与ET0呈负相关性;对新宾气象站的年均ET0影响较大的气象因素是:大气压(P)和日照时数(H),与ET0均呈负相关性。日照时数(H)是影响抚顺地区参考作物需水量ET0最主要因素。抚顺地区ET0空间变化也较大,从山区到绿洲平原ET0多年平均值呈递增趋势,ET0与海拔高度呈显著负相关。

| Abstract: | Based on the meteorogical data collected from three weather stations in recent 10 years in Funshun region,the crop evapotranspiration(ET_0) was calculated with the Penman-Monteith equation recommended by FAO.The change characteristics of monthly and annual ET_0 were analyzed.The differences of monthly and annual ET_0 were very much,but the change trend of monthly and annual ET_0 was quite resemble.The impacts of climate factors on the crop evaportanspiration were analyzed.The T_(max),RH,H and U impacted greatly on the ET_0 in the Qingyuan station.Spatial variation of ET_0 values was obvious and the value was increasing from mountainous area to plain in Fushun Region. |
