Abstract

China's northeastern Black Soil Region, one of the country's most important crop production areas, has been seriously affected by soil erosion. This study evaluated the effects of soil erosion on the long-term productivity of this region. The AA. used a modified productivity index (MPI) model to assess the current effects of soil erosion on soil productivity, as well as to predict long-term change in productivity. The model predicts a 9.6% productivity reduction over 100 years and a 48.3% reduction over 500 years
