摘要:
在乡村振兴背景下,明确农业生态系统内部各要素的变化特征、揭示农业生态系统发展阶段和转型现状,对指导山区农业发展具有重要意义。已有研究缺乏对山区农业生态系统转型机理的研究,缺乏直观揭示山区农业生态系统转型路径的分析方法,未能从乡村经济社会发展视角探索农业生态系统内部各要素在时间尺度上的转型特征。本文采用实证研究的方法,以三峡库区腹地这一典型山区农业生态系统为例,构建了农业生态系统形态转型研究框架,从乡村经济社会转型视角探究六个区县在劳动力要素变动下的农业生态系统形态的演变规律及动力机制。结果表明:(1)乡村经济社会由初期阶段到发展阶段,在农户、政府需求耦合转变下,人口结构、土地利用结构、农作物产量结构、生产投入结构、农民收入结构的变化决定着农业生态系统形态的转型。(2)农业生态系统形态存在内部结构演化的阶段性,其农业生态系统形态在2000—2008年实现了从生产社会-粗放型向经济生态-发展型转型,在2009—2019年实现了从经济生态-发展型向生态社会-集约型转型。(3)农业生态系统形态转型的驱动机理表现为经济社会、政策驱动力沿“城镇化发展、政策的响应—农业收入和非农收入差异—乡村经济社会转型—农业人口变化—土地利用转型与乡村转型—农户、政府需求耦合转型—农业生态系统结构变化—农业生态系统形态转型”这一路径联合响应。研究结果可以为山区农业结构调整、农业发展模式选择以及农业生态系统转型规律研究提供新的视角。
Abstract:
In the circumstance of rural revitalization campaign in China, for upgrading of rural economy it is quite necessary to characterize the changes in the elements of a developing agroecosystem, and describe its progress in phases, which is great significance in governing healthy mountain economy in mountainous regions of China. Although much research had been conducted relative to agroecosystem, there was hardly investigation into the mechanism of agroecosystem conversion, which should introduce a proper approach to an inclusive description of transformation path, and distinguish the phases of a conversion for each element in the agroecosystem from a perspective of rural economic and social development. Taking the Three Gorges Reservoir Area as an example, this study introduced a framework of agroecosystem morphological transformation(AMT), and used empirical research methods to explore AMT's evolution law and dynamic mechanism of the area from the perspective of rural labor changes. Results show that:(1)With the change of the rural economy and society from the initial stage to the development stage in the mountainous area, the demand of farmers and the government experienced a coupling transition, resulting in the structural changes of population, land use, crop yield, production input, and farmers' income, which further determined AMT.(2)There was periodic evolution within the agroecosystem internal structure. Agroecosystem morphology transformed from productive social-extensive type to economic ecological-development type in 2000 to 2008, followed by the transformation from economic ecological-development type to ecological social-intensive type in 2009 to 2019.(3)Driven by economy, society, and policy, AMT formed a multi-process, multi-stage joint response trajectory, which was represented by “urbanization development and policy response, agricultural income and non-agricultural income disparities, rural economic and social transformation, agricultural population change, land use transformation and rural transformation, coupling transformation of farmers and government demand, agroecosystem structural change, agroecosystem morphology transformation”. The results can provide new perspectives for studying agricultural restructuring, agricultural development mode selection, and agroecosystem transformation patterns in mountainous areas.
