Please refer to Fig.1 A and Figure 1B, the modeling side of the hydrological distribution model of the finite element control of the preferred embodiment of the present invention
Method, including step：
S1:Basin is subjected to finite element division, generates the finite element distribution in basin；
In this step, then please refer to Fig. 2.The finite element division is close according to watershed system attribute and rainfall stand control
What degree carried out, each finite element has identical or approximate underlying surface attribute, wherein a finite element by a precipitation station into
Row control, the finite element of a rainfall stand control different attribute, limited elemental area set are equal to drainage area.
Specifically, in grid-distributed hydrological model, the grid of same or similar underlying surface attribute is merged, and
The identical finite element of all kinds of basin attribute matter is generated according to rainfall stand control density.
Wherein, finite element is generated according to watershed system attribute and rainfall control density, and distribution considers river network of watershed
Concentration time.It is broadly divided into mountainous region, Plain, farmland, meadow, cities and towns, the water surface, forest finite element etc..
Being worth noting is, linear-scale is the key that processing basin precipitation runoff nonlinear problem, that is, line is used in basin

The precipitation in (meadow becomes farmland, and farmland becomes the water surface or cities and towns etc.) or basin control density has occurred when the attribute of underlying surface
When change, the distribution of basin finite element is only adjusted, the distributed model of finite element control is according to the distribution of new basin finite element
It is combined, the hydrological distribution model of finite element control is constant, and the parameter constant of all kinds of finite element models is limited after adjustment
Elemental area set is constant.The adjustment of finite element distribution is to switch to realize by finite element distributed controll, is realized according under being
The observation of pad face year border and survey data.
S2:Finite element model is generated according to the finite element of the division；
The finite element model or the first hydrological model, in this step, the finite element model is physics hydrological model,
Production stream is calculated using three water sources, calculates slope concentration using linear resesvoir, all kinds of finite elements have single underlying surface attribute, raw
At finite element model have independent and specific model parameter, each finite element model parameter such as the following table 1 to 8.

Further, the basin water-holding capacity parameter in the corresponding model of the finite element is variable, when the mankind live
It is dynamic when changing the moisture holding capacity of watershed system, pass through underground water buried depth amendment finite element model corresponding with reservoir capacity relationship
Reservoir capacity parameter.
S3:The hydrological distribution model of finite element control is generated by concentration of river network according to the finite element model.
In this step, in the hydrological distribution model generating process of finite element control, finite element model passes through concentration of river network
It calculates to basin and exports the hydrological distribution model for generating finite element control, concentration of river network uses linear resesvoir or Muskingum method
Calculation is adjusted, output result is runoff process and water level process.
When mankind's activity changes the moisture holding capacity of underlying surface, as the exploitation of basin underground water causes unsaturated zone depth to be sent out
When changing, the underground water buried depth and reservoir capacity relationship established by data for many years correct finite element model reservoir capacity ginseng
Number.Such as the first-class station WM of spring and underground water buried depth relational graph, water level storage capacity relation line See Figure 4, Fig. 5, Fig. 6 and Fig. 7：
