摘 要：
在GIS支持下,采用样区法测算了延庆县的耕地整理潜力。结果表明:县内平耕地的无效耕地系数平均为6.14%,低、中、高3种整理水平的耕地整理潜力系数是0.68%、2.10%、2.81%,相应的耕地整理潜力为109.29、337.53、451.64hm2;坡耕地的无效耕地系数平均为9.95%,低、中、高3种整理水平的耕地整理潜力系数是0.70%、3.03%、4.20%,对应的耕地整理潜力为90.68、392.52、544.09hm2。延庆县采用的测算耕地无效耕地系数的样区法、所取得的平耕地与坡耕地的无效耕地系数、不同耕地整理水平的耕地整理潜力系数可作为同类地区的耕地整理潜力测算参考,依据这两个系数测算的延庆县耕地整理潜力可作为延庆县耕地整理规划及土地整理项目可行性研究的科学依据。

摘 要：
Applying the reference area method, this paper estimated the consolidation potential for cultivated land in Yanqing County. Results show that the non-effective coefficient of cultivated land is 6.14% in average for flat area, and the potential coefficients of cultivated land consolidation are respectively 0.68%, 2.10% and 2.81% for low, middle and high consolidation levels, and the corresponding cultivated land consolidation potentials are (109.29) hm~2, 337.53 hm~2 and 451.64 hm~2. In sloping area, the average non-effective coefficient of cultivated land is 9.95%, the potential coefficients of cultivated land consolidation are 0.70%, 3.03% and 4.20% respectively in low, middle and high consolidation levels, and the corresponding cultivated land consolidation potentials are (90.68) hm~2, (392.52) hm~2 and (544.09) hm~2. The reference area method used for estimating the non-effective coefficient of cultivated land in Yanqing County, the non-effective coefficients of cultivated land both in flat and slopping areas, and the potential coefficients of cultivated land for three different consolidation levels may all be applied for the other similar counties for estimating the cultivated land consolidation potential. The cultivated land consolidation potentials estimated by using two coefficients mentioned above may be used as basic scientific data in Yanqing County for cultivated land consolidation planning and feasible study of land consolidation projects.
