摘要
基于2001-2020年统计数据,运用数理统计和区域差异法,分析了山东省花生生产地域格局的变化特征及其影响因素,为山东省花生生产的可持续发展提供科学决策依据。研究表明,近20年来,山东省花生生产呈“两减一增”局面,面积和产量分别下降33.00%和22.34%、单产增加15.93%;花生生产区域向以临沂为中心的鲁西南地区和烟台、威海、青岛所处的胶东东部地区集中;20年中有4年花生面积贡献率大于单产贡献率,有16年小于单产贡献率。研究发现,鲁东和鲁西南地区经济作物面积占比减少,是导致山东省花生种植面积下降的直接影响因素;山东花生净利润和成本利润率降低,特别是近年来的“断崖式”下跌,是导致花生种植面积和总产量逐年下降的根本原因;国内外贸易市场不稳定带来的风险,也制约了花生产业的发展。
To support the decision making for peanut production sustainability,based on the statistical data from 2001 to 2020,we use mathematical statistical approach and spatial exploring method to analyze the changes of peanut distribution and clarify the influence indicators for the changes.The results showed that during this two decades,the peanut harvested area and production decreased by 33.00%and 22.34%,respectively,while the yield increased by 15.93%.The spatial patterns of peanut concentrated to the northwest,including Linyi and east region,such as Yantai,Weihai and Qingdao.There are four years that the contribution for peanut production of harvested area is higher than that of yield,and 16 years on contrast.Through the spatial exploring method,the cropland decreased and the proportion of harvested area of the economic crops decreased,and the proportion of peanut production declined consequently.The net profits of peanut production in Shandong were lower than that in other regions and dropped in recent years,and then the harvested area and production declined regularly.In addition,the democratic and global market of peanut and its processed products was not stable,restricting the development of the peanut industry.
