双峰寺水库汛期调度运用分析

Analysis of Opetation during Flood Seasons in Shuangfengsi Reservoir

在研究武烈河流域暴雨洪水季节性变化规律的基础上,对洪水规律进行分期研究,采用分期实测流量资料推求不同频率的设计洪水,并采用分期设计洪水过程进行调洪演算,为合理分析不同时期洪水对调洪成果的影响,确定双峰寺水库洪水调度原则,综合确定水库规模提供依据。

this paper focuses on the main meteorological factors affecting the greenhouse crop water requirement include the daily mean temperature, the daily mean relative humidity and the daily solar radiation, this article takes these meteoro- logical factors in greenhouse as the input vector, the corresponding crop water requirement as the output vector, and at last establishes the predication model using the BP neural network. This predication model can portray the undefined and non- linear relationship between the factors impacting the greenhouse crop water requirement, and finally improve simulation accuracy. The effects will be verified by the example of the experimental base＇s analogy.
