黄河流域生态保护下的农业韧性时空转变与障碍因素——以陕西省为例

Temporal and spatial changes and obstacles to agricultural resilience under ecological protection in the Yellow River Basin——Take Shaanxi Province as an example

【目的】为了实现农业强国的迫切需要。【方法】首先拓展了适应性循环周期理论在农业领域的研究范围;其次,采用综合指数法和障碍度模型研究2006—2021年陕西省农业韧性的时空演变特征和障碍因素。【结果】结果表明:1)陕西省农业韧性经历了保持-释放、重组-开发、再保持三个时期,农业生产能力先减弱后增强,社会调节能力不断增强,科技创新能力发展不足;2)陕西省农业韧性空间特征显著,农业生产能力南北高中间低,社会调节能力聚集性明显,科技创新能力发展不均衡;3)科技创新能力是影响陕西省农业韧性提升的关键因素,研发投入、人力资本、科技创新能力是影响农业韧性提升的主要障碍因子。【结论】提出加强农业科技创新与推广应用,提升社会调节能力优化农业结构以及加强区域协调发展缩小地区差异的政策意见。

[Objective]In order to achieve the urgent need of agricultural power.[Methods]Firstly,the research scope of adaptive cycle theory in agricultural field was expanded.Secondly,the spatial and temporal evolution characteristics and obstacle factors of agricultural resilience in Shaanxi Province from 2006 to 2021 were studied by comprehensive index method and obstacle degree model.[Results]The results showed as follows:1)The agricultural resilience of Shaanxi Province experienced three periods:maintenance-release,recombination-development and then maintenance.The agricultural production capacity was first weakened and then increased,the social adjustment ability was continuously enhanced,and the scientific and technological innovation ability was under-developed;2)The spatial characteristics of agricultural resilience in Shaanxi Province are significant.The agricultural production capacity is high in the north and the south and low in the middle,the social adjustment capacity is clustered,and the development of scientific and technological innovation capacity is uneven;3)Scientific and technological innovation ability is the key factor affecting the improvement of agricultural resilience in Shaanxi Province,and R&D investment,human capital and scientific and technological innovation ability are the main obstacle factors affecting the improvement of agricultural resilience.[Conclusion]Policy opinions on strengthening innovation and popularization of agricultural science and technology,improving social adjustment ability,optimizing agricultural structure,strengthening regional coordinated development and narrowing regional differences are put forward.
