【摘要】 通过1979—2007年华北平原传统农业区土地利用变化探讨土地非农化规律,为粮食安全,区域土地利用优化和可持续发展提供理论参考和科学依据。构建土地非农化评价模型,运用遥感技术等方法获得的土地利用数据,对研究区土地利用非农化进行分析。研究区土地利用类型中的耕地持续减少,林地、建设用地迅速增加。土地非农化加速明显,粮食总产量受到挟制。区内土地利用变化较大,土地非农化加速;粮食单产的提高淡化了土地非农化对粮食产量的影响。土地非农化程度应与国民经济的增长速度保持一致,着眼于保障粮食安全,应调控建设用地规模;非农地中林地显著增加,宜成立统一的农林局,避免农林争地。更多还原

【Abstract】 This paper supplies academic reference and scientific base for grain supplying security—sustainable development and regional land use optimization by means of land use change and exploration into non—agriculturalization of land in traditional agricultural region in the North China Plain from 1979 to 2008.Constructed non—agriculturalization of land evaluation model and gained land use data by application of 3S technique, and analyzed non—agriculturalization of land use in the study region. Cultivated land sustainably reduced, while forestland and construction land rapidly increased in the study region. The non—agriculturalization of land accelerated dramatically, and total grain yield was subject to coercion. In the study region, land use pattern change greatly and non—agricultralization of land accelerated, an increase of grain yield per unit area weakened the effect of non—agriculturalization of land on grain yield. In order to ensure grain supplying safety, we should control construction land scale, make non—agriculturalization of land degree and national economic growth rate consistent.Because forest land proportion of non—agricultural land increasing significantly, the united agriculture and forest bureau should be established to prevent agriculture and forest from seizing land.更多还原
