泥沙含量 sediment charge
- 降雨量与悬浮泥沙含量相关程度较高。
Suspending sediment content was found to be correlated with rainfall amount. - 地表覆盖能有效地降低地表径流中的泥沙含量;
Coverage on soil could effectively decrease soil content on surface runoff. - 因此石灰华中泥沙含量的变化趋势表征流域内土壤侵蚀的变化趋势。
Therefore, the change trend of the silt content in travertine shows the change trend of soil erosion in valley.
