Problems solved by technology

[0003] Purpose of the invention: Aiming at the problem that the water resource network vulnerability assessment in the prior art only considers the water supply risk of the local entity and ignores the virtual water supply risk, resulting in an insufficiently comprehensive assessment of the vulnerability of the water resource network, the present invention proposes a regional entity-virtual water Resource Network Vulnerability Assessment Method

Embodiment 1

[0044] refer to figure 1 , this embodiment provides a vulnerability assessment method for a regional entity-virtual water resource network. The vulnerability assessment method is based on an inter-regional input-output model, combined with regional physical water consumption, virtual water consumption, and water pressure inside and outside the region. Provide technical support for regional physical water and virtual water, reduce risks inside and outside the water resource network, and alleviate regional water pressure.

[0045] The vulnerability assessment method of the physical-virtual water resources network in this region specifically includes the following steps:

[0046] Step S1: According to the inter-regional input-output method calculated by virtual water trade, calculate the regional water footprint. Wherein the regional water footprint includes an internal water footprint and an external water footprint. In this embodiment, the calculation formula of the regional w...

Abstract

The invention discloses a regional entity-virtual water resource network vulnerability evaluation method, which comprises the following steps of S1, calculating regional water footprints according toan inter-regional input and output method of virtual water trade calculation; S2, obtaining the overall vulnerability of the regional water resource network through the direct vulnerability and indirect vulnerability of the regional water resource network; and S3, evaluating the vulnerability of the regional entity-virtual water resource network according to the overall vulnerability of the regional water resource network. According to the invention, the vulnerability of the regional entity-virtual water resource is quantified; the dependence degree of the region on entities and virtual waterresources and the water supply risk caused by the dependence degree are revealed; virtual water is incorporated into a method system for evaluating the vulnerability of the water resource network, sothat the evaluation of the vulnerability of regional water resources is more comprehensive and reasonable, and technical guidance is provided for overall planning of regional entity water and virtualwater, reduction of risks inside and outside the water resource network and relief of regional water pressure.

Description

technical field [0001] The invention relates to the technical field of water resource vulnerability assessment methods, in particular to a regional entity-virtual water resource network vulnerability assessment method. Background technique [0002] With the acceleration of my country's economic development, population growth and urbanization, the problem of insufficient water supply in many regions has become increasingly prominent. District water supply includes not only physical water supply, but also water implicit in external input products and services, i.e. virtual water supply or external water footprint. Virtual water refers to the water needed to produce commodities. Once these commodities enter the trade chain, virtual water flow or virtual water trade will be generated. Water footprint refers to the total amount of water resources required by all products and services consumed by a country, region or individual within a certain period of time. The water footprin...
