Embodiment Construction

[0066] The technical solutions of the present invention will be further described below in conjunction with the examples.

[0067] figure 1 Describes the relationship among water resources, energy and food. The life cycle of water resources is divided into six links in sequence: extraction, purification, transportation, utilization, discharge and reuse: the extraction link includes surface water, groundwater, rainwater and recycled water; the utilization link includes industrial water, agricultural water, domestic water and ecological water for four purposes. Energy includes coal, crude oil, natural gas, electric energy, water energy, wind energy, light energy, nuclear energy and fuel ethanol. The life cycle of coal is divided into four links: mining, washing, transportation and utilization in sequence; the life cycle of crude oil is The sequence is divided into four links of mining, transportation, refining, and utilization; the life cycle of natural gas is divided into thr...

Abstract

The invention discloses a water-energy-grain link relationship prediction method based on a resource life cycle process. The method comprises the following steps: determining water resource, energy and grain supply amount of a prediction year through a life cycle theory and a gray prediction model; calculating the total demand of water resources, energy and grains in the predicted year; and calculating the water resource, energy or grain satisfaction degree of the prediction year, wherein the satisfaction degree is the ratio of the supply amount to the total demand amount. According to the prediction method, a life cycle theory and a grey prediction model are combined, the link relation among water, energy and grain is fully considered, the problems that an existing mathematical model method is not comprehensive in consideration and low in prediction precision are solved, multiple resource production and consumption schemes can be put together to be calculated and compared, and the difference of different resource production and consumption schemes is objectively quantified.

Description

technical field [0001] The invention relates to a water-energy-food bond relationship prediction method, in particular to a water-energy-grain bond relationship prediction method based on the resource life cycle process, which belongs to the field of natural resource management. Background technique [0002] Water, energy, and food are indispensable resources for the production and life of human society. In the process of economic and social development, water, energy, and food are interdependent and interdependent. In the context of global population growth, resource shortage, and environmental degradation, the research on the relationship between water-energy-food has become an important topic in the field of sustainable development. In November 2011, the German Federal Government held the "Water-Energy-Food Security Nexus Conference" in Bonn, pointing out for the first time that there is a complex "bond relationship" between water, energy and food. [0003] From the per...
