摘要
根据国内外的研究,总结了土壤生产力主要评价方法,分为定性和定量评价。定性评价简单易懂,主观性较强。定量评价应用较广,更为客观准确,包括单指标评价,多指标表土综合评价和多指标土体综合评价。国内外研究表明,在土壤生产力评价中应将定性评价和定量评价结合起来,完善现有的评价方法,这对于土地分等定级、土地规划和可持续利用有着重要意义。
According to the domestic and foreign research,the main soil productivity evaluation method is summarized. Evaluation method is divided into qualitative and quantitative evaluation. Qualitative evaluation is easy to understand, with strong subjectivity. Quantitative assessment is used widely and more ob}ective and accurate,including single index evaluation,comprehensive in- dex evaluation of surface soil and soil index comprehensive evaluation. Researches both at home and aboard showed that, qualitative evaluation and quantitative evaluation should be combined to consummate the current evaluation methods in the soil productivity evaluation. It is significant in land classification and grading, land planning and sustainable land use.
