| 摘 要： | 采用比较分析法分析了邢台市耕地流转的时空特点,计算出耕地保护的阀值,提出了相应的耕地资源调控措施.结果表明,近年来,虽然邢台市耕地数量持续减少,人口不断增加,人均食物消费水平不断提高,但对耕地资源的压力却没有随之恶化,反而呈现降低的趋势,原因在于耕地生产率在不断提高.依靠增加投入和科技进步,不断提高耕地生产率,是保证粮食安全的耕地资源基础和满足工业化、城市化对土地需求的根本途径.政府对耕地资源利用与调控和管理的目标应当是努力加大投入,提高耕地生产率,在保障粮食生产安全的前提条件下,合理、适度地转移耕地用途,最大限度地发挥耕地资源的效用,而不仅仅局限于严格控制耕地的转用.

| Abstract: | The purpose of the paper was to provide some countermeasure for cropland allocation in Xingtai Region, based on the temporal-spatial feature of the cropland conversion and calculating the threshold value about cropland protection. Methods of documentation and comparison were employed. The results showed that the pressure of cropland resource was gradually decreasing as the cropland area decreasing and the population growing. It depended on the progress of agricultural technology. To meet the demands of land for grain security, industrialization and urbanization,the only way of decreasing pressure on cropland was to increase input and improve agricultural technology to promote the cropland productivity ceaselessly. The government should not only pay attention to control the conversion of cropland into urban uses, but also to improve integrative benefit. |
