    摘要:

    公开出版的专业书籍中土壤可溶性盐及其组分计算公式存在诸多意料不到的错误,却没有引起大家的重视并提出修正措施,这些错误的存在可能会导致盐分含量计算结果的出错和对盐碱土分类分级的错误判定。本文选取出版日期介于2000—2020年包含土壤可溶性盐总量和阴阳离子(CO32-、HCO3-、SO42-、Cl-、K+、Na+、Ca2+、Mg2+)含量9个指标计算公式的12本专业书籍为研究对象,基于相关概念、理论基础、实验原理和实验方法进行公式推导。结果发现,9个指标共出错68次,其中HCO3-出错次数最高,为11处,占比16.2%;其次为Ca2+,10处,占比14.7%;最低的是可溶性盐总量和Cl-,4处,占比5.88%。根据9个指标的出错特征,将其归纳为系数2、换算系数、公式、指代意义和公式不规范5种出错种类。5种出错种类中,换算系数出错次数最高,31处,占比45.6%;其次为公式,13处,占比19.1%;最低的是系数2,4处,占比5.88%。通过对土壤可溶性盐及其组分计算公式出错种类的特点和原因解析,指出问题所在,并提出了纠正措施,以期为相关公式的修正提供借鉴。

    Abstract:

    【Objective】There are many errors in soil soluble salt and its component formula in published professional books. However, this has not attracted enough attention and no corrections have been made. Such published data may induce wrong results in soil soluble salt and its components calculation and subsequently wrong judgments in the classification or grading of saline-alkali soils.【Method】12 professional books published during 2000~2020 and containing 9 indexes (soil soluble salt, CO32?, HCO3?, SO42?, Cl?, K+, Na+, Ca2+, Mg2+) were selected for use in deriving their formulas based on related concepts, theoretical basis, experimental principles and experimental methods.【Result】Results suggested that there were 68 total errors using the 9 indexes. Among the 9 indexes, HCO3? recorded the highest frequency of errors, i.e. 11 times and accounted for 16.2%. It is followed by Ca2+ which recorded 10 times in total and accounted for 14.7% while soil soluble salt and Cl? recorded the lowest, i.e. 4 times in total (5.88%). Based on analyses of the characteristics of errors with the 9 indexes, the errors were found to occur as five different aspects categorized as coefficient 2, conversion coefficient, formula, reference and formula unstandard. Out of the five categories, conversion coefficient recorded the highest frequency of errors, i.e. 31 times in total (45.6%); followed by formula at 13 times (19.1%) and the coefficient 2 with the lowest of 4 times (5.88%).【Conclusion】 Errors in soil soluble salt and its component formula were discovered in published data and corrective measures were applied accordingly. The characteristics and causes of errors in calculating the formula of soil soluble salt and its components were suggested. Also, our results suggest reference values for the corrections of relevant formula.
