| Abstract: | 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. |
