Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with specific embodiments.

[0035] Step 1: Obtain the basic data of pig breeding in the breeding area of ​​Yancheng City, Jiangsu Province, including basic breeding information such as the number of live pigs, breeding area, feed production, feed formula, feed input, power consumption of pens, transportation fuel consumption, etc. Meteorological data such as temperature, precipitation, and wind speed in the study area.

[0036] Step 101, the scope of the breeding area is the breeding status of 74 farmers in Yancheng City, Jiangsu Province in 2017.

[0037] Step 102. Obtaining data content includes basic breeding information such as the number of live pigs on hand, breeding area, feed formula, feed input, power consumption of pens, transportation fuel consumption, etc.;

[0038] Step 103. Sources and methods of data acquisition include household surveys, questionnaire surveys, expert interviews, sta...

Abstract

The invention discloses a method for measuring and calculating greenhouse gas emission in the pig breeding industry. The method comprises the following steps: step 1, obtaining basic breeding data oflive pigs in a breeding area, which comprises basic breeding information such as live pig stock, breeding floor area, feed production, feed formula, feed input, colony house power consumption and transportation oil consumption, and meteorological data such as temperature, rainfall and wind speed of a research area; 2, calculating greenhouse gas emission of live pig breeding in the aspects of feedprocessing, colony house energy consumption, transportation and the like through an IPCC greenhouse gas calculation method; 3, the greenhouse gas emission amount of the pig breeding excrement management link under the specific climate background is calculated through a Manure-DNDC model; and step 4, integrating calculation results of all the life cycles to obtain the total greenhouse gas emissionamount of the live pigs in the whole life cycle. Compared with a single coefficient method, the method is more accurate in calculation of greenhouse gas emission of the pig breeding industry.

Description

technical field [0001] The invention belongs to the research on the carbon emission of pig breeding, and in particular relates to a method for measuring and calculating the greenhouse gas emission in the pig breeding industry by combining the IPCC greenhouse gas calculation method with the Manure-DNDC model. Background technique [0002] Economic development has brought about continuous growth in the demand for pork products. China's annual per capita pork consumption in 2019 increased by 20.14% compared with 2010. The rapid increase in the number of pigs raised has caused a large amount of greenhouse gas emissions, which will have a profound impact on agricultural production, ecological environment and social and economic development. In recent years, under the background of global climate change, the calculation of greenhouse gas emissions in the industry life cycle has become a hot research issue in the field, which is of great significance to green production, industrial...
