摘  要:
利用模糊数学原理和多元统计分析方法,对浏阳植烟土壤肥力状况进行了综合评价.结果表明,浏阳烟区土壤肥力存在着广泛的变异,属于I级和IV级土壤肥力的面积均较小,分别占该烟区总面积的0.65%,1.67%;属于II级和III级土壤肥力的面积均较大,分别占总面积的48.23%和49.45%.占浏阳烟区总面积70.88%的5种主要植烟土壤类型相比较,土壤肥力综合指数(IFI)高低依次表现为:红黄泥田>青泥田>黄泥田>沙泥田>黄沙泥田.

摘  要:
Based on methods of multivariate statistical analysis and principles of fuzzy mathematics,the comprehensive evaluation of soil fertility of Liuyang tobacco-growing areas was conducted.The results indicated that there existed significant variation for the soil fertility of Liuyang tobacco-growing areas.The areas of grade I and grade IV are both smaller,accounting for 0.65% and 1.67% of the total Liuyang tobacco-growing areas,respectively;the areas of grade II and grade III are both larger,accounting for 48.23% and 49.45% of the total tobacco_growing areas,respectively.Comparison among five main soil types whose areas accounted for 70.88% of the total Liuyang tobacco-growing areas showed that the integrated fertility index(IFI) was in the order of red yellow mud field > blue mud field > yellow mud field > sand mud field > yellow sand mud field.
