本文通过大量剖面资料,应用综合数值分析法分类,取得了南疆各类土壤的主成份方程、散点图和类间界限指标等结果,为南疆例行分类系统的修订,提供了较充分依据。经32个剖面验证表明,其结果可供今后南疆土壤调查制图参考。这样的属性分类,还有利于野外识别土壤和确定其改良的难易程度,使调查成果发挥实效。着重讨论了南疆盐土与盐化土壤的分类(级)的界限指标。其划分盐土的指标主要有五项,关键是整盐、Na~+和3.43%的表盐。
In this paper, a large number of profile data, the application of integrated numerical analysis of classification, obtained in southern Xinjiang various types of soil main component equations, scatter plots and class boundaries between the indicators and other results for the Southern Routine Classification System revision provides a more adequate in accordance with. The 32 profile verification shows that the results are available for future reference to soil mapping in southern Xinjiang. Such attribute classification, but also conducive to the field to identify soil and determine the ease of improvement, so that the survey results to be effective. The boundary index of the classification (level) of saline land and saline land in South Xinjiang is emphatically discussed. There are five main indicators for the classification of saline soil, the key is the whole salt, Na ~ + and 3.43% of the table salt.
