Problems solved by technology

We know that rainwater plays a major role in the water ecological environment of the basin, but due to the lack of planning and management methods, human activities have seriously caused the degradation of the most critical and active factor (vegetation) in the water cycle

Embodiment 1

[0089] Below, the Ziya River Basin is taken as the research area, 2008 is selected as the base year, and the above steps are taken as an example to further illustrate the method of the present invention.

[0090] According to the precipitation values ​​obtained from 409 precipitation stations in and around the Ziya River Basin, the inverse distance weighted interpolation method (IDW) was used to interpolate the precipitation in the Ziya River Basin to obtain the precipitation distribution map (see figure 1 ) and contour plots (see figure 2 ), taking precipitation as the total water resource P of the basin.

[0091] Obtain latent heat of vaporization, maximum air temperature, minimum air temperature, saturated water vapor pressure, canopy surface net radiation, air density, soil heat flux, specific heat of air at constant pressure, canopy conductance, saturated water vapor pressure, and actual water vapor in the river basin pressure, aerodynamic conductance, leaf area index, ...

Abstract

The invention relates to the field of water conservancy, specifically to a river basin water resource planning and utilization method. The method includes the steps of measuring a rainfall value of a river basin, and estimating a vegetation transpiration value, a soil evaporation value, a land area evapotranspiration quantity and an evapotranspiration quantity of the river basin, and obtains water storage variables of the basin according to a green water quantity and a blue water quantity in the river basin and by virtue of models and formulas, thereby achieving the purpose of water resource planning and utilization. The method provided by the invention can be accurately and reliable applied to basin water resource planning, ecological environment evaluation, ecological water demand accounting, basin hydrologic cycle process simulation and the like, has a wide range of application, and is a method of planning seeking for sustainably utilizing water resources based on an eco-hydrological idea; and the method achieves a guiding function for water resource management, eco-water environment construction, industry and agriculture industrial planning and flood control and drought relief, thereby enabling an industry and agriculture industrial structure and water resource development and utilization to be more scientific and more reasonable, and promoting sustainable development of regional economy.

Description

technical field [0001] The invention relates to the field of water conservancy, in particular to a method for planning and utilizing water resources in river basins. Background technique [0002] With the increasingly prominent water-related ecological environment problems, the protection of the ecological environment has attracted widespread attention in today's society, and people have increasingly realized the importance of harmonious coexistence with the natural ecosystem for the sustainable development of human beings. The change of regional hydrological process caused by the development and utilization of water resources will inevitably have an impact on the regional ecological environment system, and the change of regional ecological environment, especially the change of vegetation ecosystem, is bound to have an effect on the regional hydrological process. Facing the reality of increasing shortage of global water resources, look for a new method and theory of basin wa...
