Description :
The Bashang area located in the semiarid agropastoral zone, represents a typical degraded ecosystem under intensified human activities. This region has undergone profound land use changes during the past century. Natural grasslands had been progressively cultivated, and subsequently, part of cultivated lands had been abandoned by farmers due to severe desertification. The objectives of this study are to identify changes in soil properties following 8, 30, and 50 years of grassland cultivation relative to natural grassland; to evaluate effects of land abandonment in a 1- to 50-year chronosequence on soil properties and vegetation establishment in Bashang area of northern China.
