摘要:

为探明黄淮烟区以烟为主农田碳排放特征,以田园综合体为基本研究单元,分析其在植烟前后农田生态系统碳足迹变化,明确主要碳排放环节,为以烤烟为种植结构主体的农田区域实现绿色低碳管理提供理论依据。本研究选取山东某地田园综合体,该田园综合体自2019年起,转变为以烟为主的田园综合体。通过对当地不同种植系统种植过程的原材料投入、农业管理措施、产量等要素进行问卷调查,利用生命周期法核算2018年和2020年农田生产的碳足迹及其组成。2020年单位面积经济效益为41548元/hm2,为2018年的3.2倍。2020年单位面积碳排放量为185.45 t/(hm2·a),较2018年增加108%,单位面积碳汇量为548.9 t/hm2,较2018年减少30%;单位面积碳足迹和单位产量碳足迹分别下降48%和40%,碳生产效率和碳生态效率分别下降58%和75%,碳经济效率提高103%;烤烟种植体系单位面积碳排放量为119.40 t/(hm2·a),是区域平均值的64%,碳汇量为98.8 t/(hm2·a),是区域平均值的18%。烤烟种植是弱的碳活动种植体系,农田系统变更为以烤烟为种植主体后,整个区域的碳汇量减少,碳排放量增加,碳足迹降低。

Abstract:

To investigate the carbon emission characteristics of tobacco-dominant agricultural fields in the Huang-Huai region, this study took the rural complex as the basic research unit, and analyzed the changes in the carbon footprint of farmland ecosystem before and after tobacco planting. The main carbon emission links were identified, which could provide theoretical basis for the realization of green and low-carbon management in tobacco-dominated farmland areas. This study selected an agricultural complex in Shandong, which had transformed to a tobacco-dominant model since 2019. Through a questionnaire survey of raw material input, agricultural management measures, yield and other factors in the planting process of different local planting systems, the carbon footprint and composition of farmland production in 2018 and 2020 were calculated using the life cycle method. In 2020, the economic benefit per unit area reached 41548 yuan/hm2, which was 3.2 times of that in 2018. Carbon emission per unit area in 2020 was 185.45 t/(hm2·a), with an increase of 108% compared with 2018, and carbon sink per unit area was 548.9 t/(hm2·a), with a decrease of 30% compared with 2018. Carbon footprint per unit area and carbon footprint per unit yield decreased by 48% and 40%, carbon production efficiency and carbon ecological efficiency decreased by 58% and 75%, and carbon economic efficiency increased by 103%. The carbon emission per unit area of flue-cured tobacco planting system was 119.40 t/(hm2·a), 64% of the regional average, and the carbon sink was 98.8 t/(hm2·a), 18% of the regional average. Flue-cured tobacco cultivation was a weak carbon active cropping system. After the farmland system was changed to flue-cured tobacco as the main planting system, the carbon sink of the whole region decreased, carbon emissions increased, and carbon footprint decreased significantly.
