| 摘 要： | 生态需水量核算问题中,国内外常用的几种潜在蒸散量计算模型具有一定的限制性,为此,结合东北地区特点,以哈尔滨市为例,选取时间序列指标数据,对比分析常用计算模型的适用性及不足,提出修正并优化Hargreaves(HM) 模型的方法并进行参数修定．修正后HM模型的计算结果与PM模型的相关系数达0.826,相对均方差为0.119,相关性较好,可满足哈尔滨市蒸散量的计算．

| Abstract: | Many researches focus on the ecological water demand accounting problem. But it has a certain restriction of several potential evapotranspiration models commonly used in China and abroad. Combined with the northeast area characteristic, the paper has chosen Harbin as the example. It has selected a series time of indicator data and compared the applicability and disadvantage about these models. The paper proposes the method to amend and optimize the Hargreaves (HM) model. It also revised the parameters. The correlation coefficient of amending HM and the PM calculations is 0.826, and the relative mean squared deviation is 0.119. It has a good correlation of calculating the evapotranspiration calculation of Harbin. And it will lay the foundation for the quantitative accounting ecological water demand of the northeast region. |
