r is 0.0827 at the significance level. Rainfall erosivity in most regions of Kazakhstan
exhibits a tendency to increase, indicating that the possibility of water and soil erosion caused by precipitation is continuously increasing.
Precipitation is one of the main external factors contributing to soil erosion.
Therefore, in this section, we quantitatively discuss the relationship between rainfall erosivity and precipitation. Rainfall erosivity for most stations exhibited an
upward trend. For further analysis of the correlation between them, a linear
relationship was established in Fig. 5.2. The calculation results show that the correlation coefficient between them is r = r2 (0.968) = 0.984 (P < 0.0001), proving that
