Embodiment Construction

[0026] The water footprint sustainability evaluation method provided by the invention comprises the following steps:

[0027] (1) Calculation of regional water resource overload

[0028] Regional water resource overload refers to the difference between the sustainable water resources in the region and the water footprint of production, which represents the water shortage caused by production. A positive value represents regional water resource storage, and a negative value represents water resource overload.

[0029] WRO=WRC-WFP=Q*0.4-WFP (1)

[0030] In the formula: WRO is the overload of regional water resources; WRC is the sustainable water resources in the region, which is the product of the total amount of regional water resources (Q) and the threshold value of water stress index (WTA=0.4); Q is the total amount of regional water resources, Refers to the total amount of surface and underground water produced by local precipitation, that is, the sum of surface runoff and...

Abstract

The invention discloses a water footprint sustainability evaluation method, comprising the steps of: calculating the difference between the regional sustainable water resource amount and the regional production water footprint to obtain the regional water resource overload; and calculating the difference between the regional consumption water footprint and the regional production water footprint , to obtain the regional water resource trade deficit; calculate the difference between the regional sustainable water resources and the regional consumption water footprint, and obtain the regional water resource deficit; evaluate the regional water footprint according to the regional water resource overload, regional water resource trade deficit, and regional water resource deficit Persistent. The present invention reflects the relationship between production, consumption, trade and water resource endowment by comparing and studying the regional water footprint and the sustainable water resources in the region, and incorporates the impact of trade into the method system of water footprint evaluation, making the evaluation of water footprint more scientific and efficient. It is reasonable and has certain technical guiding significance for my country to coordinate physical water-virtual water to achieve national water security.

Description

technical field [0001] The invention belongs to the technical field of sustainability evaluation methods, in particular to a water footprint sustainability evaluation method. Background technique [0002] More and more studies have shown that regional water resource shortage is not always caused by the increase in water consumption brought about by local socio-economic development, and the consumption demand of external regions can also affect the sustainability of local water resources through trade. The impact of consumption and trade on water resources and water environment can be represented by the concept of water footprint. The 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 footprint of a region refers to the total fresh water consumption and pollution within the region’s boundaries (Hoekstra et al. ., 2011). Water footprint sust...
