Abstract

The invention discloses a calculation method and system for a balance model of water, soil, grass and livestock in a pastoral area, and relates to the technical field of mathematical model calculation. The method takes the carrying capacity of water resources, land resources and grassland resources as the bottom line, aims to maximize the comprehensive benefits of economic and ecological benefits, and takes the comprehensive balance between "water-soil-grass-livestock" in pastoral areas as the criterion to determine reasonably The development scale of water and soil resources, the planting structure of agriculture and animal husbandry, the mode of production of animal husbandry and the appropriate stocking capacity, realize the sustainable utilization of water, soil and grass resources in pastoral areas, the benign development of the ecological environment and the sustainable development of social economy.

Description

technical field [0001] The invention relates to the technical field of mathematical model calculation, in particular to a calculation method and system for a balance model of water, soil, grass and livestock in a pastoral area. Background technique [0002] my country's pastoral areas are arid and rainless, water resources are scarce, water and soil resources do not match, grassland and livestock balance contradictions are prominent, grassland desertification and degradation are serious, and the ecological environment is very fragile. [0003] Problems in the current pastoral balance calculation: [0004] (1) Most of the previous studies were based on water-grass-livestock balance calculations, and insufficient consideration was given to soil, an important factor affecting the planting of irrigated artificial grasslands; [0005] (2) Previous studies mostly calculated with the goal of maximizing economic benefits; [0006] (3) Most of the previous studies were limited by t...
