| 摘 要： | 水稻灌溉需水量是一个地区农田水利规划、灌溉系统规划的重要参数,也是合理开发利用水资源、水资源调度和实现地区可持续发展的重要依据。在水量平衡的基础上,对蒸散发项和渗漏项的计算方法做出改进,其中对蒸散发项的改进参考了新安江模型中二层蒸散发模型的计算方法,渗漏项的计算在实验的基础上采用半经验半理论的方法改进。最后,结合当地的... |

| Abstract: | Rice irrigation quota is not only an important parameter for irrigation planning and irrigation scheme,but also an important basis for the rational development and utilization of water resources,water resources regulation and achieving sustainable development in a region.Based on the water balance equation,the calculation method of evapotranspiration and leakage terms are ameliorated in this paper.In which,the calculation method of the second floor evapotranspiration Model in the Xin'anjiang Model is refere... |
