建昌地区气候变化对蒸发皿蒸发量的影响

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.
