Embodiment 1

[0054] like Figure 1-Figure 4 As shown, the Jinghe River Basin is located in the central part of the Loess Plateau of China (106°20′~108°42′E, 34°46′~37°19′N), with a drainage area of ​​45421 km 2 , most of the basin belongs to the Longdong Loess Plateau. The north of this area is the loess hilly area, the central part is the loess remnant area, the southwest is the mountain forest area, and the southeast is the mountains and rivers and Hechuan area. The terrain and geomorphic features are rich, and it is a typical area for the study of the Loess Plateau. The Jinghe River Basin originates from the eastern foot of Guandong, Jingyuan County, Ningxia Hui Autonomous Region. The basin is 450km long and has a total drop of 2180m. It is the primary tributary of the Wei River and the secondary tributary of the Yellow River. The basin is deep in the continent and has a typical temperate continental climate. The average temperature of the basin is 8°C for many years, the average temp...

Abstract

The invention discloses a river runoff research method, and relates to the technical field of hydrogeology. The method comprises the following steps: determining an influence factor influencing the actually measured runoff volume of the river; D; determining a research reference period and a change period; E; establishing an influence factor simulation situation route by utilizing a distributed hydrological model and a control variable mathematical method; S; selecting a corresponding hydrological model according to the simulation situation route; D; determining the simulated perpetual averagerunoff volume of the river by utilizing the influence factors and the hydrological model; D; determining the change value of the actually measured runoff volume of the river; D; determining the influence quantity of the influence factor on the river runoff according to the simulated river years of average runoff and the river actual measurement runoff change value; and determining the contribution rate of the influence factors on the actually measured river runoff of the river, wherein the contribution rate is used for judging the influence of each influence factor on the river runoff. By adopting the research method, the influence of climate change and human activities on river runoff can be accurately evaluated, and a scientific basis is provided for reasonable and effective managementof water resources.

Description

technical field [0001] The invention relates to the technical field of hydrogeography, in particular to a research method for river runoff. Background technique [0002] Human activities and climate change are two important factors affecting the hydrological cycle. Intensified human activities and climate change in recent years will greatly change the hydrological cycle process and cause changes in the temporal and spatial distribution of available water resources. Among the various elements of the water cycle in a watershed, runoff is the most important component of water resources management, and its changes affect the water use patterns of various industries. By studying the causes of runoff changes and the interaction between the influencing factors, effective countermeasures to deal with these changes can be put forward in time. Climate change includes factors such as rainfall, radiation, temperature, and wind; human activities include water diversion, water resource d...
