摘  要:
利用闽侯县耕地地力样区调查资料和改进的耕地分等成果,进行闽侯县耕地等级折算系数研究.结果表明,闽侯县及其因素指标区耕地利用等指数与农作物年标准粮产量关系拟合的最佳模型是对数函数模型,其拟合效果最好,均达极显著水平(r=0.969-0.870).全县及丘陵山地、山间盆地和沿海平原区最高和最低质量耕地折抵系数分别为4.94、5.22、3.64和1.60.

摘  要:
Using the fertility sample data and the improved grading results of cultivated land in Minhou,researched quality-grade conversion coefficient of minhou cropland.The results indicated that in Minhou County and the factor areas,the best model between the utilization index of cultivated land and grain yield in the standard of crops is the logarithmic function model,which was highly significant(r = 0.969~0.870).The highest and lowest quality offsetting coefficients of farmland about county,hilly,mountain basin and coastal plain were 4.94,5.22,3.64 and 1.60.
