Desertification is one of the most serious environmental problems on a global scale. China suffers from desertification over large areas. Landscape boundaries profoundly influence the structure and function of landscapes, and influence ecological processes both locally and over large scales. Data on soil properties and vegetation collected on three 110 km parallel transects across sandy land-steppe...
Future changes in precipitation will induce changes in the erosive power of rainfall and hence changes in soil erosion rates. In this study we calculated downscaled mean annual precipitation and USLE rainfall erosivity (R) for time periods 2030 through 2059 and 2070 through 2099 in Northeast China using future precipitation predicted from six GCM models under three emissions scenarios. To accomplish...
The 30-min rainfall erosivity index (EI 30 ) is commonly used in the Universal Soil Loss Equation for predicting soil loss from agricultural hillslopes. EI 30 is calculated from the total kinetic energy and the maximum 30-min rainfall intensity of a storm. Normally, EI 30 values are calculated from breakpoint rainfall information taken from continuous recording rain gauge charts,...
