According to the conventional meteorology observation data and the water surface evaporation of 20 m2 experimental pool from 1997 to 2000 in Changji,the paper sets up the forecast model of water surface evaporation of the Xinjiang plain area based on BP Neural Network.
利用新疆地矿局昌吉地下水均衡试验场1997—2000年非冻结期20 m2水面蒸发池的蒸发量数据,基于BP神经网络,建立新疆平原地区水面蒸发量的预测模型,结果表明:模型构建简单,误差较小,且所需资料易于获得。
There are low precipitation and high evaporation in Xinjiang while water surface evaporation main stem from water loss of river runoff.
农业是新疆经济的主要支柱和优势产业,而新疆的农业是灌溉农业,渠系众多,水面蒸发量损失较大,合理地预测水面蒸发量是有效利用水资源和促进农业发展的基础。
In order to make ET estimated conveniently,this research analyzed the correlation between water surface evaporation(E0) and crop evapotranspiration(ET) measured by large scale lysimeter,and the variation of evaporation coefficient.
为了更方便地估算作物蒸发蒸腾量,以大型称重式蒸渗仪实测的冬小麦蒸发蒸腾量(ET)为依据,分析了水面蒸发量(E0)与实测蒸发蒸腾量(ET)的相关性,并研究了蒸发系数的变化规律。
