摘要
采用运用多元统计分析法研究了邵阳塘田市镇土地整理对土壤肥力质量的影响。结果表明,干扰土壤中各肥力因子指标权重变化较大,未干扰土壤变化相对较小;对土地整理干扰土壤肥力影响较大的有pH、全钾、速效钾、碱解氮,对未干扰土壤肥力影响较大的为碱解氮、缓效钾和全磷,而pH对未干扰土壤肥力影响最小。土地整理干扰后,表层土壤综合肥力指数(IFI)减小;受干扰的表层土样多属V级肥力等级,未干扰土样属于中等肥力水平比例较高。
The paper used multivariate statistical analysis to study the effects of land consolidation on soil fertility quality.The results showed that the weights of various fertility factors in disturbed soil had bigger changes than in undisturbed soil;in disturbed soil,pH,total potassium,available potassium and alkali nitrogen were greatly influenced factors,while in undisturbed soil,alkaline nitrogen,slow-acting potassium and total phosphorus were the factors,pH was the least influential factor.After land consolidation,the integrated fertility index(IFI)of surface soil decreased;the disturbed soil samples were mainly in V-grade fertility level,while undisturbed soil samples had larger proportion of the medium-fertilizer level.
