Spatio-temporal evolution characteristics and impact mechanism of high-quality agricultural development of the Yellow River Basin in Shaanxi Province

In order to research the high-quality agricultural development at a smaller scale, based on the county-level panel data, an evaluation index system was constructed from the five dimensions, e. g. green development, product quality, industrial benefit, production efficiency and scale management. Taking the Yellow River Basin in Shaanxi Province as the research area, the spatio-temporal evolutionary characteristics and impact mechanism of high-quality agricultural development were investigated by comprehensively use AHP-entropy combination weighting method, TOPSIS method and Geodetector. The results showed that: 1)The level of high-quality agricultural development in the Yellow River Basin of Shaanxi Province has increased by more than 5 times from 2003 to 2017, and production efficiency and industrial benefit have been greatly improved, but the level of green development has dropped significantly; 2)The county-level differentiation and pattern change of high-quality agricultural development level are obvious, and its spatial evolution unfolds along the main stream and tributaries of the Yellow River. The high-level areas are located on the periphery of the Xi''an metropolitan area, and expand along the Weihe and Luohe River, then become a whole area in the Guanzhong Plain Region. The low-level area moves inward from main stream of the Yellow River in northern Shaanxi and tends to be dispersed; 3)The spatio-temporal evolution of high-quality agricultural development level in the basin is the result of the interaction of multiple factors. The main influencing factors for the differentiation of development level are per capita arable land, total investment in fixed assets, transportation superiority, urbanization rate and water resources. In conclusion, the high-quality agricultural development should be driven by the high-quality green agriculture, construction of new infrastructure, new urbanization and major projects, precise regional evaluation and countermeasures.
