| 摘 要： | 农业现代化是农业发展的必然趋势,是国民经济快速增长的基础。分析区域农业现代化水平的空间分异规律为区域经济发展、城乡融合及生态环境建设提供基础资料。该研究以陕西关中平原为研究区,从农业生产、经济收益、人才、生态4个维度,构建区域农业现代化评价指标体系,探讨陕西关中平原农业现代化发展水平时空变化规律及影响因素。结果表明：1）2010－2020年关中平原农业现代化水平中高西低,整体呈现快速－缓慢提升趋势,西安市及邻县农业现代化达到成熟阶段;2）农业生产与产出水平提升强度相对较大且持续上升,人才与农业生态发展相对落后;3）区域农业现代化相对发展强度在时空上呈现"均衡发展－两极发展"趋势,各县域发展能力从相差较小转变为差异显著,这取决于区域现代农业类型;4）关中平原农业现代化表现出聚集模式的空间特征,且在发展格局上呈现方向性减弱、发展重心向东南方向迁移特征,但空间格局仍以东－西方向为主。研究区域农业现代化发展现状与空间分布规律有利于区域农业"对症下药",因地发展农业模式,对推进区域农业现代化具有重要意义。

| Abstract: | Agricultural modernization has been the overwhelming trend as the rapid growth of the economy in recent years. Taking the Guanzhong Plain, Shaanxi Province, China as the study area, a systematic analysis was made on the spatial differentiation and influence mechanism of agricultural modernization level, particularly for the regional economic development, urban-rural integration, and ecological environment construction. There was the regional difference of agricultural modernization in the grain-producing area, where the Weihe River running from the west to East offered the favorable irrigation conditions suitable for crop planting. An evaluation index system of regional agricultural modernization was constructed from the four dimensions, including agricultural production, economic income, talents, and ecology. The temporal and spatial variation and influencing factors were proposed for the development level of agricultural modernization using AHP, entropy weight method, global Moran''s I index model, and Sellers Discretionary Earnings (SDE) method. The results showed that: 1) The level of agricultural modernization was high in the middle and low in the west from 2010 to 2020, indicating a rapid and slow upward trend as a whole. It infers a developed stage in agricultural modernization. 2) The improvement intensity of agricultural production and output level was relatively large and continued to rise, whereas, there was a backward development of talents and agricultural ecology. 3) The relative development intensity of regional agricultural modernization presented the trend of "balanced development bipolar development" in time and space. The development capacity of each county changed from a small to a significant difference, particularly depending on the type of regional modern agriculture. 4) There were the spatial characteristics of the aggregation mode. The development pattern showed the weakening directionality and the migration of development focus to the southeast, but the spatial pattern was still dominated by the east-west. 5) There were outstanding spatiotemporal grades and relative development intensity of agricultural modernization, indicating the consistent trends of spatiotemporal changes. The development intensity of agricultural modernization in the districts and counties was related to the type of modern agriculture. The regional economic level, policy system, and natural conditions of agricultural production posed a great impact on the agricultural modernization pattern. Two suggestions were proposed to realize the regional agricultural modernization. First, the agrochemical products can be cut down to promote the agricultural and ecological environment. Second, the green production mode was integrate the three industries. A new business or production mode can integrate the technical potentials in the other industries and industrial chain nodes, in order to improve the agricultural production level and output capacity in sustainable agricultural mechanization. |
