| 摘 要： | 利用生产成本分析河北省耕地利用集约度的发展变化特征,通过建立近20年河北省耕地利用数据库,确定反映集约度的评价指标,基于生产成本计算耕地利用集约度,并对研究区集约度变化特征进行研究。研究结果表明：河北省耕地利用集约度经历了“两快两稳”4个发展阶段,区域间的耕地集约度是栾城≈遵化＞张北,劳动集约度在耕地利用集约度中的比重是张北＞栾城＞遵化。研究发现,耕地利用集约度与经济发展水平有明显相关性,且随着经济的发展,资金集约度的比重会逐渐上升,而劳动集约度比重会逐渐下降,体现了资金投入逐步替代劳动投入的趋势;研究区内耕地利用集约度的变化受地块区位和微地形的影响。

| Abstract: | The characteristics of inter-annual, inter-regional and regional agricultural land use intensity are studied based on the production cost. The German classical formula is used to compute the intensive use degree of Luancheng, Zunhua and Zhangbei counties of Hebei Province, based on the database of Hebei. Intensive use of arable land in Hebei Province experienced a four-stage development progress of "two-speedy and two-steady". The intensity distribution of regional agricultural land is Luancheng≈Zunhua＞Zhangbei, the proportion of labor-intensity to the agricultural land use intensity is Zhangbei＞Luancheng＞Zunhua. With the economic and technological development the agricultural land use intensity is rising, and the inter-regional land use intensity is affected by the location of plots, resources and other conditions such as micro topography. |
