摘要
收集1980～1999年合肥市耕地、人口、粮食等资料,定量分析在城市化快速发展下耕地的数量、质量变化和耕地减少的形式以及人口、粮食的变化,并用回归法分析它们的变化趋势。研究认为,在2005,2010年合肥市食物保障能力分别为97%和95%,对粮食生产与其影响因素进行了灰色关联分析,提出提高粮食产量的对策和实现途径。
Collect data (1980～1999) on cultivated land, population and food in Hefei city and quantitative analysis is done on the change of cultivated land's quantity and quality and on reducing form of land.
