摘要
基于人工神经网络模型反演了盘锦市1970年至2015年间的逐月蒸散发量,并采用区域水量闭合法验证该模型的精确度。根据模拟结果总结了盘锦市蒸散发量的年内及年际分布规律,并分析了不同土地覆盖类型所对应的蒸散发演变特性,从而验证了人工神经网络法在城市尺度蒸散发演变规律分析中的适用性,为盘锦市的水文循环特性研究提供参考。
The current paper estimated the monthly evapotranspiration amount in panjin City for the period1970 ― 2015 utilizing the artificial intelligence model,and validated the accuracy of the model using the area water balance method.The annual and inter-annual distributions of evapotranspiration in the panjin City were summarized based on the modelled results,and the evolutionary characteristics of evapotranspiration corresponding to various land cover types were analyzed.The paper validated the applicability of artificial intelligence method in analyzing city-scale evolutionary regularity of evapotranspiration,and provided reference for the investigation of hydrological cycle characteristics in panjin City.
