摘要
采用建昌气象站1960-2014年蒸发皿蒸发量资料,运用相关分析等气候统计诊断分析方法,研究了该地区蒸发量变化特征和主要影响因子,为区域性水平衡研究提供技术支撑。结果表明:建昌地区蒸发量减少趋势明显,气候倾向率为-49.28mm/10a,年蒸发量减少15.2%;地面平均温度、日照时数和风速是影响蒸发皿蒸发量的主要因子;模拟预测蒸发量模式准确率为87.3%。研究成果可为地方水循环水平衡研究提供依据和参考。
In order to regional water balance studies provide technical support,using the Climate Diagnostic Statisti？cal analysis Jianchang 1960-2014 weather in pan evaporation data,using correlation analysis,research evaporation characteristics of the region and the major changes affecting factors. The results showed that：reduce evaporation Jian？chang region was evident that climate trend rate-49.28mm/10a,15.2% reduction in evaporation;Average surface temperature,sunshine and wind speed are the main factor in pan evaporation;Simulation model to predict the exact amount of evaporation was 87.3%. The research results can provide the basis for local water cycle water balance studies.
