摘　　要：在介绍研究区域概况的基础上,依据《丰县统计年鉴》中人口、耕地面积、农作物播种面积、粮食播种面积、粮食单产等数据,采用耕地压力指数模型,分析了耕地压力指数各相关因素随时间的变化过程以及耕地资源的紧张程度。研究表明,19992005年丰县耕地压力较大,县域范围内粮食供需一直处于不安全状态,今后丰县耕地供需矛盾将会更加突出,粮食安全将面临更大压力。为缓解耕地压力,实现耕地资源的可持续利用,确保丰县耕地和粮食供需平衡,稳定和提高县域范围内的粮食生生产能力,提出了合理保护耕地的对策与建议：一是采用最严格的耕地保护制度,保护现有耕地资源;二是加大土地开发整理与复垦力度,增加耕地面积;三是加大农业科技投入,提高粮食单产。Based on the introduction of the general situation of research region,pressure index model of cultivated land is adopted according to the data of population,cultivated land area,crop sowing area,grain sowing area,and unit grain yield in the Statistical Yearbook of Fengxian County.The change of relevant factors of cultivated land pressure index over time is analyzed,as well as the tension level of cultivated land resources.Research shows that the pressure on cultivated land is relatively great in Fengxian County in the years 1999-2005.Grain supply and demand is still under the unsafe state.There will be more prominent contradiction between supply and demand of cultivated land in Fengxian County in the future,and the grain security will under greater pressure.Several countermeasures are put forward to ease the pressure on cultivated land in Fengxian County,in order to realize the sustainable use of cultivated land resources,to ensure the supply and demand balance of grain and cultivated land,and to stabilize and improve the grain productivity in Fengxian County,such as protecting the current cultivated land resources by the strictest protection system of cultivated land,enhancing the intensity of land development and reclamation,enlarging the area of cultivated land,increasing the agricultural sci-tech input,and improving the grain unit yield.
