Inner Mongolia Water Footprint Account Accounting and Water Resources Evaluation Analysis

Abstract

On the basis of expounding the concepts of virtual water and water footprint, and summarizing the calculation method of water footprint based on the virtual water content of products, taking Inner Mongolia Autonomous Region as an example, the water footprint and its related indices (water scarcity degree) of 12 administrative regions from 1995 to 2020 were calculated. , water resources dependence, water resources self-sufficiency rate and water footprint intensity), analyzed the time series of water footprint and water footprint intensity, and further explored the temporal and spatial differences of water footprint in each administrative region through the water footprint pressure index. The results show that, from the time point of view, the water footprint shows an increasing trend, while the overall water footprint intensity shows a downward trend. There are differences in the degree of dependence and the degree of externalization of the water footprint.
