山东省农业可持续发展空间分异研究*

本文选取山东省2012年—2020年的数据，通过构建山东省区域农业可持续发展指标体系，利用熵值法对山东省整体及各地级市农业可持续发展进行综合分析和评价；同时借助地理空间分异图以及三维趋势图分析山东省农业可持续发展水平的空间变化状况。经一系列分析后，结果显示：（1）山东省整体农业可持续发展水平不断提升，各区域之间农业可持续发展水平差距日益缩小。（2）从空间格局分布来看，山东省各地级市农业可持续发展水平分布不均匀且具有不均衡性，序列两端区域稳定。（3）从东西方向来看，农业综合发展水平由西向东平滑过渡，东部地区优于西部地区，呈阶梯状。南北方向上呈现南部与北部弱于中部地区的趋向。各区域在空间上仍存在差异但也呈缩小的趋势，但空间差异格局仍然存在。最后根据上述的研究结论，提出相关建议：（1）西部地区要依靠技术创新改造其传统农业存在的弊端，加大现代化农机设备的投入力度；（2）东部地区依靠其独有的资源优势，加快新技术、新产品的开发；（3）中部地区依托其地形的特点，开发多样化的新型农业发展模式。

STUDY ON SPATIAL DIFFERENTIATION OF AGRICULTURAL SUSTAINABLE DEVELOPMENT IN SHANDONG PROVINCE*

This paper selects the data of Shandong province from 2012 to 2020, through constructing the index system of regional agricultural sustainable development in Shandong Province, and uses entropy method to comprehensively analyze and evaluate the agricultural sustainable development of Shandong province as a whole and prefecture-level cities. At the same time, the spatial variation of agricultural sustainable development level in Shandong province was analyzed with the help of geographic spatial differentiation map and three-dimensional trend map. After a series of analysis, the results show that :(1) the overall level of agricultural sustainable development in shandong province is constantly improving, and the gap of agricultural sustainable development between different regions is narrowing day by day. (2) From the perspective of spatial pattern distribution, the sustainable agricultural development level of all prefecture-level cities in Shandong province is uneven and unbalanced, and the two ends of the sequence are stable. (3) From the east-west perspective, the level of comprehensive agricultural development transitions smoothly from west to east, and the eastern region is better than the western region in a ladder shape. The trend of south and north is weaker than the central region. There are still spatial differences among different regions, but the pattern of spatial differences still exists. Finally, based on the above research conclusions, some suggestions are put forward :(1) western China should rely on technological innovation to reform the disadvantages of traditional agriculture and increase the investment in modern agricultural machinery and equipment; (2) The eastern region relies on its unique resource advantages to speed up the development of new technologies and products; (3) The central region relies on the characteristics of its terrain to develop diversified new agricultural development modes.
