Improvement and application of a three-dimensional ecological footprint evaluation model for grass and livestock

This Compared with the single-dimensional ecologi-cal footprint evaluation, the three-dimensional ecological footprint evaluation of grass and livestock has the characteristics of categor-ical characterization of natural resource flow occupation and stock consumption status of grass and livestock, and at the same time can reflect the relationship between natural resources and sustain-able development more accurately. In this paper takes the grass-livestock balance relationship as the entry point, based on the eco-logical footprint and ecological carrying capacity, and uses the 3D ecological footprint improvement model to calculate the depth of grass-livestock footprint, the breadth of grass-livestock footprint and the 3D ecological footprint of grass-livestock in the agricul-tural and pastoral areas of each league and city in Inner Mongolia from 2018 to 2020, and then decodes the causes of formation. The results of the simulation experiment show that: at the social level, the more rural population, the larger the grass-livestock ecological footprint; at the economic level, industry accounts for a large pro-portion, there is industrial competition for food, and the grass-live-stock ecological footprint is small; at the natural level, the annual rainfall is more, and the corresponding grass-livestock ecological footprint is small.
