Influence of Reclamation on Grassland Slope in Farming-Pastoral Areas, Inner Mongolia

Abstract:

In the majority of farming-pastoral areas, Inner Mongolia, grassland slope was reclaimed recent years due to the increase of population. The resulting deterioration of ecological environment problem is becoming more and more serious. In 2012, the effect of reclamation on erosion, vegetation and soil characteristics were researched in Saiwusu of Damao County, Inner Mongolia. Results show: 1. Severe wind erosion in spring, also severe water erosion in summer were on the slopping field. 2. After cultivation, annual herb such as Salsols collina, Corispermum declinatum, Chenopodum aristatum, Artimisia annua et al. grew vigorously, however perennial herb such as Stipa krylovii, Leymus chinensis and Agropyron cristatum were inhibited. 3. Soil nutrient sharp declined due to the erosion and harvest. In short, the grassland which converted to slopping field increases more than 5 times of soil erosion, soil fertility drops 30%, and vegetation changed completely after 1 year; 4 years later, soil fertility drops 50%, vegetation becomes sparse, soil water and fertility is poor, crop yield is low, the slopping field is not fit to continue farming, large abandoned.
