安徽省油料生产与种植面积动态变化响应研究

Dynamic response of oil crop production and planting area in Anhui province

基于地理信息技术和数理模型,探究安徽省油料生产与种植面积动态变化及空间匹配关系,分析油料生产对面积变化的敏感程度。结果表明:安徽省油料作物种植面积呈减少趋势,油料密集区分布于皖中,油料稀疏区分布于皖北4市及皖南2市。油料生产效率同比提高了53.6%,且表现出皖北高、皖中次之、皖南低的地域差异性分布。考察期内油料产量与面积空间匹配年份达60%,匹配度均值为0.328,属低匹配类型。对比2002~2009年和2009~2017年两个阶段,安徽省油料生产对种植面积响应的敏感度下降,中﹑高敏感型减少了50%。

Based on GIS and mathematical model,explored the dynamic change and spatial matching re-lationship between oil production and planting area in Anhui province,and analyzed the sensitivity of oilproduction to area change.The results showed that the planting area of oil-bearing crops in Anhui prov-ince is decreasing,the oil-bearing concentrated area is distributed in the middle of Anhui province,andthe oil sparse areas were distributed in the four cities in the north and two cities in the south of Anhuiprovince.The oil production efficiency increased by 53.6%from the year before,and showed the re-gional difference distribution of high in the north part of Anhui,lower in the middle of Anhui and lowestin the south of Anhui.The spatial matching year of oil production and area was 60%,and the averagematching degree was 0.328 in the investigation period,which belongs to low matching type.Comparedwith the two stages of 2002~2009 and 2009~2017,The sensitivity of oil production in Anhui province tothe response of planting area decreased,and the sensitivity of medium and high sensitivity decreased by50%.
