【摘要】：基于碳效应视角分析归纳了黄土高原退耕区农户的现实农业生产模式,通过深入剖析不同模式之间碳效应的差异,再次明确了低碳农业生产模式"经济效益与生态效益双赢"的核心理念。研究表明:退耕还林工程建设促使黄土高原地区农业土地利用方式和农业生产结构不断调整、优化,农户逐渐分化为粮食作物主导型、设施经济作物主导型、经济林木主导型、家禽家畜主导型4种类型;农户在生产经营过程中,为追求自身利益最大化,对不同生产要素进行筛选、组合,逐步形成了11种黄土高原地区典型的农业生产模式;不同模式之间碳效应、碳密度存在明显差异,退耕任务对不同模式的碳效应和碳密度具有明显的影响,退耕规模是影响不同模式碳排放密度差异的重要因素;实现经济效益和生态效益双赢是低碳农业发展的关键所在,通过对黄土高原退耕区不同类型农户农业生产模式的碳效率比较分析,最终农户的低碳农业生产模式显化为种养复合循环生产模式、设施有机生态生产模式、旱区节水生产模式、设施养殖循环生产模式4种类型。
[Abstract]:Based on the perspective of carbon effect, the paper analyzed and summarized the real agricultural production mode of farmers in the Loess Plateau, and analyzed the difference of carbon effect among different models. The core idea of "economic benefit and ecological benefit win-win" in low-carbon agricultural production mode is defined again. The research shows that:. The construction of returning cropland to forestry project promotes the adjustment of agricultural land use mode and agricultural production structure in the Loess Plateau. The farmers gradually divided into four types: the dominant type of grain crop, the dominant type of facility cash crop, the dominant type of economic forest, and the dominant type of poultry and livestock. In the process of production and management, in order to maximize their own interests, farmers screen and combine different factors of production and gradually form 11 typical agricultural production models in the Loess Plateau. There are obvious differences in carbon effect and carbon density among different models. The task of returning farmland has obvious influence on carbon effect and carbon density of different models. The scale of returning farmland is an important factor affecting the difference of carbon emission density in different models. The key to the development of low-carbon agriculture is to realize the win-win of economic and ecological benefits. The carbon efficiency of different types of farmers' agricultural production modes in the Loess Plateau is compared and analyzed. In the end, the low carbon agricultural production model of farmers can be divided into four types: compound cycle production model, organic ecological production model, water-saving production model in arid area and circular production mode in facility farming.
