英那河地处北方半湿润地区,其降水的显著特点是在时空上分布极不均匀。由于降水分布不均,该地区洪涝及干旱灾害很严重。因此研究该地区的洪水预报对该地区的防汛抗旱工作、水资源的合理利用与保护、水利工程建设与管理及工农业生产与人民生活等方面有着重要的意义。研究选用新安江模型、API模型和TOPMODEL对英那河上英那河史家堡流域的产汇流规律及洪水预报进行研究应用,并对三个模型在研究区域应用的结果进行比较分析。
The river is located in the northern semi-humid areas, the salient features of its precipitation is very uneven distribution in time and space. Due to the uneven distribution of precipitation, the floods and drought disasters in this area are very serious. Therefore, studying flood forecasting in this area is of great significance to flood control and drought relief in the region, rational utilization and protection of water resources, construction and management of water conservancy projects, industrial and agricultural production and people’s livelihood. The study selected Xin’anjiang model, API model and TOPMODEL to study the law of runoff generation and flood forecasting in the Shijiabao Basin of the Yingnahe River and the comparative analysis of the results of the application of the three models in the study area.
