| 摘 要： | 分析了腐殖质厚度法和土壤有机质含量法存在的缺陷，提出了以土壤有机质含量的厚度为基础，以各类土壤中等肥力水平的有机质厚度为标准厚度来计算土壤有机质含量的厚度指数的方法－厚度指数法，用该方法计算的厚度指数能更好地反映植被好坏程度和土壤肥力的高低。

| Abstract: | This paper analyses the deficiency of two methods of the organic matter amount and humus layer thickness of the soil.It puts foward a new method of thickness index of soil organic matter amount to determine the thickness index of the amount of organic matter with a standard thickness obtained from the organic matter thickness in different types of medium fertility soils and with the thickness of organic matter amount in soil as the basis of this method,to replace the two methods of organic matter amount and humus layer thickness of the soil.The results obtained in this way better reflect the conditions of cover and soil fertility. |
