| 摘 要： | 应用GIS技术和空间自相关分析方法,分析了1990年以来环渤海地区县域人均粮食占有量的空间演化特征.结果表明,研究区县域人均粮食占有量空间自相关特征明显,高-高聚集和低-低聚集趋势增强;人均粮食增长更多表现出空间分布的随机性,地理集中趋势不明显;县域人均粮食占有量以上升为主,增长类型以总产低、快速增长型为主,粮食生产重...

| Abstract: | The area along Bohai Rim,including Beijing,Tianjin,Liaoning,Hebei and Shandong,is one of the important grain production bases that guarantee food security in China.With the acceleration of area urbanization in the past 20 years,the grain production and consumption patterns along Bohai Rim have brought about significant changes.Agricultural statistics of the area along Bohai Rim at county-resolution level for the time period of 1990-2008 is collected and the GIS technique as well as other tools such as the M... |
