Embodiment 1

[0042] figure 1It is a flow chart of a method for evaluating the conversion of real water and virtual water provided by Embodiment 1 of the present invention. This embodiment is applicable to quantitatively evaluating the conversion of real water and virtual water. The method can be evaluated by evaluating the conversion of real water and virtual water Converting means to perform, the means can be implemented by software and / or hardware, generally can be integrated in a computer, the method specifically includes the following steps:

[0043] Step 110, obtaining the physical water consumption of each economic sector in the preset area.

[0044] The physical water consumption of each economic sector in a preset region (such as a province) can be calculated according to the statistical data of water resource usage in the preset region.

[0045] Among them, physical water includes surface water and groundwater, such as river, river and lake water and shallow groundwater. Therefo...

Embodiment 2

[0075] figure 2 It is a flow chart of a method for evaluating the conversion between physical water and virtual water provided by Embodiment 2 of the present invention. This embodiment is an example based on the above embodiment. In this embodiment, the preset region is Hebei Province to evaluate the entity The conversion of water and virtual water, the method specifically includes the following steps:

[0076] Step 210, obtain the entity water consumption of each economic department in Hebei Province;

[0077] According to the "Hebei Provincial Water Resources Bulletin" and the first national economic census, the entity water consumption of 30 economic sectors of agriculture, industry and service industry in Hebei Province was obtained. The 30 economic sectors are: agriculture, forestry, animal husbandry and fishery, coal mining and washing industry, oil and natural gas mining industry, metal ore mining and dressing industry, non-metallic ore and other mining and dressing i...

Embodiment 3

[0094] Figure 4 It is a schematic structural diagram of a device for evaluating the conversion of real water and virtual water provided by Embodiment 3 of the present invention, as shown in Figure 4 As shown, the device for evaluating the conversion between real water and virtual water provided by the embodiment of the present invention includes: a real water consumption acquisition module 410 , a transfer matrix determination module 420 and a conversion amount determination module 430 .

[0095] Among them, the physical water consumption acquisition module is used to obtain the physical water consumption of each economic department in the preset area;

[0096] The transfer matrix determination module is used to determine the transfer matrix of physical water and virtual water of each economic sector based on the input-output model according to the physical water consumption;

[0097] The conversion amount determination module is used to determine the conversion amount of p...

Abstract

The invention discloses a method and an apparatus for evaluating the conversion of real water and virtual water. The method comprises: obtaining the consumed water of various economic department entities in a preset region; according to the consumed water of the entities, determining the water transfer matrix for the real water and virtual water of the various economic departments based on an input-and-output model; and based on the water transfer matrix for the real water and virtual water, determining the conversion amount of the entity consumed water and the virtually consumed water among the various economic departments. According to the invention, it is possible to evaluate quantitatively the conversion amount of the real water and virtual water among the various economic departments so as to deeply understand the flow process and characteristics of water resources in the economic and social system, to provide a new approach for the study of social water circulation and to provide scientific basis for industry reconstructing and water resource integrated regulation and management.

Description

technical field [0001] Embodiments of the present invention relate to water resource evaluation and management technologies, and in particular to a method and device for evaluating the conversion of physical water and virtual water. Background technique [0002] The shortage of water resources has become a "bottleneck" that affects the sustainable development of more and more countries and regions. In order to deal with the shortage of water resources, some measures currently taken, such as cross-basin water diversion projects, dam construction projects, etc., cannot completely solve the regional water resource problem. Especially in the context of economic globalization, the free competition of products and the unevenness of regional development have further exacerbated the contradiction between water supply and demand in water-scarce areas. This contradiction cannot be resolved by merely regulating physical water resources. [0003] British scholar Allan first proposed t...
