中文摘要	通过构建县域层面农业现代化水平评价指标体系,基于Theil指数、Wolfson极化指数及障碍度模型等方法揭示陕西省农业现代化水平时空格局演变特征及障碍因素。结果表明:①2003-2017年陕西省农业现代化水平整体经历上升(2003-2009年)-稳定(2010-2014年)-下降(201 5-2017年)演进过程;②Theil指数和Wolfson极化指数整体呈缓慢上升趋势,区域内部不均衡性是陕西省农业现代化水平区域差异不断扩大的主要原因,其平均贡献率达86.81%;③陕西省农业现代化水平呈现中部高,南北低的时空分布格局,关中渭北旱原、宝鸡市和榆林市北部区县是农业现代化水平高值区和热点地区,且高值区沿主要河流分布以及向三大地理区域过渡地带扩展的趋势明显;④质量效益是陕西省农业现代化水平的最大准则层障碍因素,年平均障碍度为41.58%,设施农业发展水平、劳均经济作物产出以及畜产品产出水平是主要障碍因子。最后,针对陕西省农业现代化发展突出问题,结合黄河流域农业高质量发展战略需求提出相关对策建议。
英文摘要	This study constructed a comprehensive evaluation index system for county agricultural modernization level. Theil index and Wolfson polarization index, as well as an obstacle degree model were used to analyze the characteristics of the spatial and temporal patterns of agricultural modernization level and obstacles in Shaanxi Province. We found that:(1)The agricultural modernization development pattern in Shaanxi Province can be divided into three stages, including the rising period(2003-2009), the stable period(2010-2014), and the declining period(2015-2017).(2)Theil index and Wolfson polarization index were slowly rising, and intraregional inequality was the main reason that regional differences of agricultural modernization level in Shaanxi Province expanded, which contributed 86.81% of the overall Theil index.(3)Agricultural modernization level in the Guanzhong Plain Region was higher than that of the Loess Plateau Region and the Qinling-Daba Mountains Region, and the arid area of northern Weihe River and Baoji City, as well as northern Yulin City were the high-level regions and hot spots in Shaanxi Province. Counties with high level of agricultural modernization are distributed along some main rivers and expanded from the Guanzhong Plain Region to the geomorphic transition zone.(4)Agriculture development quality was the biggest sub-index level obstacle factor, with an annual average obstacle degree of 41.58%. The key obstacles that affected agricultural modernization level were facility agriculture development, output efficiency of economic crops, as well as the production of animal products. Finally, this article put forward some suggestions for agricultural modernization development in Shaanxi Province and high-quality development of agriculture in the Yellow River Basin.
