Soil Erosion Risk Assessment Based on the Research of Impact Factors:Taking Anxi County as an Example 来自 知网 喜欢 0 阅读量: 32 作者:XU Jinlin,X Zha 摘要: Soil erosion risk assessment is crucial to soil and water conservation monitoring,harnessing and so on.With the increase of national ...
Among the six factors, it is noted that the R_m factor was found increasing due to global climate change. To offset the increase in soil erosion associated with the R_m factor, we explored a possible option of reducing the C factors of bare lands in this study. The Shihmen reservoir ...
Soil slopeRunoffSoil lossSoil erosion and the resulting sedimentation constitute major natural hazards that increase land degradation in the Mediterranean region. Understanding the behavior of soil erosion is of particular importance to control the degradation of productive soils. Therefore, a portable ...
The second part of the 19th century was wetter than the first part, but not to an extent that could greatly increase the uncertainly of the erosion model more than other factors. A nonlinear trend toward an increase from minimal values in the period between 1947 and 1964 to 30% higher ...
Inadequate awareness will increase heat stress risks which require proper techniques to manage (Nunfam et al., 2019). The climate change-risk has both positive and negative impacts on mining. Waterlogging and flooding can impede mining operations, whereas drought has a positive impact as mining ...
It is noteworthy that all GAM partial effect plots are centred on the mean, meaning that the increase or decrease shown in the y-axis is reflected in the average predicted value of severity (i.e., the effect is relative to the mean). The exception is lagged effects (in this case 0–...

Compared with historical data (1959–1990), we found that river water in our study area was more acidic because of coal emissions from industrial activities in Sichuan and Guizhou Provinces. As a result of urbanization and the increase in domestic sewage, the average Cl/Na+ molar ratio at ...
The particulate matter caused by sand and dust affects human health (Singer et al., 2003) and leads to a dramatic increase in the rates of anemia, kidney and liver diseases, and asthma (Micklin, 1996; Orlovsky et al., 2001). Show abstract Evaluating soil erosion by introducing crop ...
The percentage of the FVC-increased area reached 87.86% with an increase rate of 0.142. Factors such as precipitation, temperature, elevation, slope and financial investment for soil conservation were important drivers of local FVC change. Our findings reveal that climatic factors along with the ...
