The Impact

&lt;p&gt;The impact of climate change on soil erosion is pronounced in high mountain area. In this study, the revised universal soil loss equation (RUSLE) model was improved for better calculation of soil erosion during snowmelt period by integrating a distributed hydrological model in upper Heihe river basin (UHRB). The results showed that the annual average soil erosion rate from 1982 to 2015 in the study area was 8.1 t ha&lt;sup&gt;-1 &lt;/sup&gt;yr&lt;sup&gt;-1&lt;/sup&gt;, belonging to the light grade. To evaluate the influence of climate change on soil erosion, detrended analysis of precipitation, temperature and NDVI was conducted. It was found that in detrended analysis of precipitation and temperature, the soil erosion of UHRB would decrease 26.5% and 3.0%, respectively. While in detrended analysis of NDVI, soil erosion would increase 9.9%. Compared with precipitation, the effect of temperature on total soil erosion was not significant, but the detrended analysis of temperature showed that the effect of temperature on soil erosion during snowmelt period can reach 70%. These finding were helpful for better understanding of the impact of climate change on soil erosion and provide a scientific basis for soil management in high mountain area under climate change in the future.&lt;/p&gt;

Wild Fires

Wild fires in a mountain area cause severe runoff. The runoff causes secondary mal-effects such as soil erosion and environmental contamination. Korea had suffered from serious soil yield problems at Imha reservoir in 2003. The muddy flow in the reservoir lasts for an years at that time and the water resources problem had prevailed around the watershed. But there was no reliable method in predicting the amount of soil yield and developing count measures against soil erosion. The goal of this research is to find the sustainability transition of land cover characteristics in a wild-fired watershed. For the success of this research, experimental watershed which had suffered from wild-fires was operated last five years. With the collected field data, the transition of land cover characteristics of watershed was analyzed. It was found that the land cover factor was increased about one hundred times at first year after the wild fire. Then it decreases constantly until it remains stable condition which is reached at fourth year after wild-fires.
