| 摘 要： | 根据1978～2008年相关数据,分析了邯郸市耕地-粮食-人口系统的动态变化,计算了耕地压力指数,并分析了该指数的动态变化及成因。结果表明:1978年以来邯郸市耕地面积及其人均量持续减少;粮食总产量及人均产量总体呈增加趋势;受其影响,最小人均耕地面积和耕地压力指数呈现相似的变化趋势。最后探讨了缓解耕地压力的调控策略,指出保持区域内一定数量的耕地、种植高产作物、严格控制人口增长是缓解耕地压力的重点。

| Abstract: | According to related data in Handan City during 1978-2008,the dynamic change of arable land-grain-population system was analyzed.The arable land pressure index was calculated,the dynamic change and causes were analyzed.The results showed that: since 1978,the arable land area and amount per capita in Handan City continuously decreased;the total grain yield and yield per capita increased;affected by that,the minimum arable land area per capita and pressure index indicated similar variation trend.Finally,strategies for releasing arable land pressure were discussed,such as maintaining a certain amount of arable land area,cultivating high-yielding crop and controlling population growth strictly. |
