论文在分析河北省近50年来耕地数量动态变化的基础上，对1988－1995年间河北省耕地资源数量下降的状况及其构成进行了详尽的剖析，探讨了河北省耕地减少的原因，并提出了减缓耕地减少的对策。农业结构调整占地（占耕地总减少量的47％）是河北省耕地减少的主要原因；其次是非农建设占地和灾害毁地，分别占总减少量的22％和30％；在新增加的耕地类型中，开荒和复垦的比例分别占耕地总增加量的49％和44％，是耕地增加的主要来源。 |

Based upon which, the situation and composition of cultivated land loss during 1988～1995 are examined. The causes of cultivated land loss are discussed and the countermeasures are advanced. It is found out that the adjustment of agricultural structure is the main cause of cultivated land loss, which accounts for 47% of the total amount of cultivated land loss; land devoting to non-agricultural constructions and damaged by natural hazards are the secondary causes, which respectively account for 22% and 30% of the newly added types of cultivated land, reclamation and reuse of abandoned land are the main sources of cultivated land increase, which respectively account for 49% and 44% of the total increased cultivated land. |
