摘要
在"双碳"目标背景下,种植业低碳化发展是一种必然的趋势,对减少种植业碳排放和促进农业可持续发展具有重要意义.文中基于2012-2021 年数据对张掖市种植业生产中所产生的碳排放量进行测算,并构建多元回归模型对张掖市种植业碳排放影响因素进行分析.结果显示:①2012-2021 年张掖市种植业碳排放总量年均增长率为 0.87%;②各生产要素均对张掖市种植业碳排放具有显著影响,但在影响程度上按照化肥、农膜、翻耕和农业机械的顺序依次减弱.因此,为了实现张掖市种植业低碳化发展,倡导应用有机肥代替化肥,采用喷灌和滴灌等技术,加大废旧农膜回收利用等减排措施,促进种植业生产碳减排.
Abstract
Under the background of the"double-carbon"target,the low-carbon development of planting industry is an inevitable trend,which is of great significance to reduce the carbon emissions of planting industry and promote the sustainable development of agriculture.Based on the data from 2012-2021,this paper calculates the carbon emission generated in the planting industry production in Zhangye City,and constructs a multiple regression model to analyze the influencing factors of the carbon emission in the planting industry in Zhangye City.The results show that:(1)The average annual growth rate of the total carbon emission of planting industry in Zhangye City from 2012 to 2021 is 0.87%;(2)All production factors have a significant impact on the carbon emission of planting industry in Zhangye City,but the influence is weakened in the order of chemical fertilizer,agricultural film,ploughing and agricultural machinery.Therefore,in order to realize the low-carbon development of planting industry in Zhangye City,this paper advocates the application of organic fertilizer instead of chemical fertilizer,adopt sprinkler irrigation and drip irrigation technologies,and increases the emission reduction measures such as the recycling and utilization of waste agricultural film,so as to promote the carbon emission reduction of planting industry.
