土壤质地分类及其在我国应用探讨

摘要:
土壤质地是土壤重要的物理特性之一,严重影响土壤的持水、通气等特性,研究统一土壤质地分类制意义重大。针对我国土壤质地分类制混用的现象,文章在介绍国内外主要的土粒分级标准,比较四种土壤质地分类制的特点,回顾第二次土壤普查初期采用前苏联的卡庆斯基制,后期采用国际制的基础上,重点对比了我国的国标、各部门行标或规范等所运用的土壤质地分类标准。研究发现我国目前还没有普遍采用统一的土壤质地分类系统。土壤质地分类推荐采用美国制。

Abstract:
【Objective】 Soil texture is one of the important physical propertries of soil, which seriously affects the water holding and ventilation characteristics of soil. It is significant to study the unified soil texture classification system.【Method】In view of the chaos phenomenon of using soil texture classification systems in China, the study introduces some important standards for grading of soil particles prevailing home and abroad, compares the characteristics of four soil texture classification systems, and retrospects the use of the experiment-CCCP’s Kazhinski system during the first phase of the Second National Soil Survey of China and the shift to the international system later, with focus on comparison of the standards for soil texture classification adopted by the nation and various departments in the country. 【Result】Nowadays, there is no such a soil texture classification system that can universally be used in China.【Conclusion】It is, therefore, recommended to use the American system .
