degree of soil erosion的意思|示意

Based on the analysis and study on the physical properties of karst soil in Guizhou Wujiang river basin in different type of vegetation and different degree of erosion.

本文分析研究了贵州乌江流域喀斯特土壤在不同植被类型和不同侵蚀程度条件下的土壤主要物理性质。

The degree of soil erosion reduces.

水土流失程度减轻；

The results show that the identifying sign of soil erosion is not erosive surface but the degree of soils conservation and the change of soils thickness.

结果表明，塬区土壤侵蚀的确定依据不是侵蚀面，而是土层保存程度和土层厚度的变化。

In terms of being favorable to soil and water conservation, we confirm the rainfall, vegetation cover degree , thickness of litter and the amount of soil erosion as monitoring projects.

从有利于水土保持的角度，把降雨量、植被覆盖度、枯落物厚度和土壤流失量等作为水土流失监测项目；

The size of the slope directly affects the degree of soil erosion and the difficulty of production.

坡度的大小直接影响土壤冲刷的程度和成产的难易。

When the number of downfall days is less than 20 annually, soil erosion degree increases along with the increase of downfall days.

当多年平均大雨日数小于20日时，土壤侵蚀程度基本上随大雨日数的增加而增加；
