Abstract

The invention provides a measuring and calculating method for distinguishing live pig and pork production water footprints in different scales of production scale. The method comprises the following steps: determining a measuring and calculating area and a measuring and calculating time period; acquiring feed crop and product production data in the measuring and calculating time period; acquiringthe consumption data of live pigs; obtaining annual slaughter quantity, annual product yield, live weight, pork product processing water consumption, live pig excrement content, pollutant content in excrement and pollutant discharge standards of a calculation year; calculating the feed crop production water footprint of the calculation year; calculating a water consumption footprint of the feed crops; calculating by-product water footprints of the feed crops; calculating unit water footprints of the concentrated feed and the coarse feed; calculating feed water footprints of live pigs of various scales; calculating a drinking water footprint and a service water footprint of each scale; calculating pollutant water footprints of each scale; representing live pig production water footprints, and distinguishing green water footprints, blue water footprints and gray water footprints; measuring and calculating pork production water footprints. According to the method, the measurement and calculation precision of regional live pig and pork production water footprints is effectively improved.

Description

technical field [0001] The invention relates to the calculation of the consumption of different types of water resources and the impact on the water environment of pig and pork production under different production scales in the region, specifically relates to a method for measuring and calculating the water footprint of pig and pork production based on the supply chain of pork products, and particularly relates to a method for distinguishing Production-scale method for estimating the water footprint of hog and pork production. Background technique [0002] Quantitative accounting of pig and pork production's water consumption and impact on water quality is an important prerequisite for ensuring the development of the animal husbandry industry while implementing the most stringent water resource management system. Based on the four production scales of scattered breeding, small-scale, medium-scale and large-scale, analyze the composition of the water footprint of pig and por...
