Embodiment Construction

[0042] In order to understand the technical content of the present invention more clearly, the specific implementation method of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] Such as figure 2 , image 3 As shown, the present invention firstly divides the annual runoff sequence into the base period (natural period) and the period of human activities, and further performs restoration calculation on rainfall and temperature hydrological elements. Establish a hydrometeorological database and a spatial database respectively. The spatial database includes data such as land use, soil, and terrain elevation, and then select a large-scale watershed distributed hydrological model to simulate and carry out simulation calculations under different scenarios. and the impact of human activities. The method of the invention can adopt the international common numerical calculation fortran language to carry out program...

Abstract

The invention provides a method for quantifying influence on basin water resources by climate change and human activities. The method comprises the following steps: S1, dividing a long sequence reference period; S2, carrying out restore calculation on hydrologic features of rainfall and temperature; S3, establishing a foundation database; S4, carrying out large-scale basin distributed hydrologic simulation; S5, quantitatively representing influence sub-items of the climate change and the human activities. According to the method provided by the invention, a basin distributed hydrologic model, a hydrologic feature restore technology and a sub-item quantifying method are effectively coupled, the method for quantifying the influence on the basin water resources by the climate change and the human activities is established, and the method has important significance to decisions such as basin water resource evolution analysis and identification, water source project planning layout and water resource space allocation in a varying environment.

Description

technical field [0001] The invention belongs to the technical field of water resources engineering, and in particular relates to a quantification method for the impact of climate change and human activities on water resources in a river basin. Background technique [0002] With the increasing impact of global climate change and human activities, the spatial distribution of water resources in the basin and the structure of supply and demand have been affected to varying degrees, and this impact has attracted national and even global attention. Water resource security is an important basic condition for the sound and rapid development of the national economy and society. In recent years, countries around the world have carried out many studies on the impact of climate change and human activities on water resource security. The results show that: climate change directly causes rainfall, Hydrological factors such as runoff and evaporation change in time and space cycles, while h...
