摘要: 运用定量与定性相结合的分析方法,研究了1949~1998年河北省种植制度变化轨迹,结果表明:①种植结构变化与作物比较效益直接相关,90年代以来全省棉花面积下降、大豆和蔬菜面积上升都是比较效益作用的结果。②全省稳定了以一年两熟为主体的熟制体系,种植模式向复合、高效发展,种植指数提高,相当于比1952年扩大播种面积151.1万hm2。③今后河北省种植业发展的方向是优质、高效,并注重高产,目标是提高生产系统的复合度和资源利用效率。

Abstract: Cropping system transition from 1949 to 1998 in Hebei province was studied. Results showed that ① changes in cropping structure is directly related to comparative benefit among crops. The decline of cotton area and the increases of soybean and vegetable areas in the last decade were the resulsts of changes in comparative benefits;② the cropping system in Hebei is mainly characterized by two-cropping-a-year and cropping systems are tending to be integrated and higher efficient. The planting index increase has resulted in the enlargement of crop sowing area by 1.51 million ha compared with that in 1952;③the directions for crop production in the future are to gain high quality, high efficiency and high yield as well and the goals are to improve the complexity and resource use efficiency.
