Embodiment Construction

[0032] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0033] A product industrial water footprint accounting method based on regional and seasonal water resource pressure indexes provided by the present invention will be divided into three parts: the first part is to propose the regional water resource pressure index and its evaluation model, and the second part is to propose the seasonal water resource pressure Index and its evaluation model, the third part is to construct the calculation method of product industrial water footprint based on regional water resources stress index and seasonal water resources stress index. The specific steps are:

[0034] Part I: Regional Water Resources Stress Index and Its Evaluation Model

[0035] Step 1: Propose the Regional Water Stress Index (RegionalWaterStressIndex, RWSI). For a specific geographical area, the volume capacity of water resour...

Abstract

The invention relates to a product industrial water footprint calculating system combining regional water resource pressure and seasonal water resource pressure influences, aiming to obtain a water footprint value reflecting the environmental influence degree of a certain product. A calculation method is characterized by comprising the following steps: providing a regional water resource pressure index and an evaluation model thereof; providing a seasonal water resource pressure index and an evaluation model thereof; providing a water footprint equivalent for a reference unit to comprehensively represent the influences of regional and seasonal differences on product industrial water footprint, and contributing a product industrial water footprint calculation method based on the regional water resource pressure index and the seasonal water resource pressure index. By adopting the method, different influences of industrial production activities on fresh water resources in different production regions and different manufacturing periods can be shown, and the problem of comparison among product industrial water footprints in different regions and different manufacturing periods is solved.

Description

technical field [0001] The invention relates to a method for calculating water footprints in the industrial production process of products, and in particular, relates to the calculation of industrial water footprints of products while considering the influence of water resources in different regions and seasons. Background technique [0002] Water resources are precious resources that human beings rely on for survival and development. However, with the rapid development of human industrialization, the contradiction between supply and demand of water resources has become increasingly serious, and the current situation of global water resource shortage has become increasingly prominent. However, while the shortage of water resources is becoming more and more serious, humans are polluting water sources on a large scale, which further leads to the deterioration of water quality. Therefore, the problem of water resources is not only a resource problem, but also a major strategic...
