摘要

土壤侵蚀危险性评价研究中

必须首先对土壤的有效厚度进行分析。本文结合陕南秦巴山地土壤厚度图的编制工作

探讨了用趋势面分析和回归分析等数学模型编制土壤厚度图的方法和步骤。从编图效果看

数学方法逻辑性强

图斑准确率高

图件能够较好地反映土壤厚度的实际分布和变化情况。

Abstract

Soil efficient thickness should be analysed in the appraising of erosion risk of soil

In this paper

combined with the charting of soil thickness of QinBa hill in southern Shaanxi

the method and step to chart soil thickness is studied with trend surface analysis and regression analysisy etcc..From the results of charting it can be seen that the mathematical method has nature of high logic

high accuracy of map spot

and that the maps made with this method could reflect the actual distribution and va riation of the soil thickness.
