- Abstract:
-
Grain for Green Project (GGP) is an important ecological and environmental construction and protection engineering project in China, and it has great influence on vegetation cover and soil erosion. The Revised Universal Soil Loss Equation (RUSLE), together with precipitation, soil type, DEM and vegetation cover, was used to investigate the impacts of GGP on soil erosion from 2000 to 2010 in Luohe River Basin, northern Shaanxi Province, China. Results showed that: (1) farmland decreased while forestland and grassland increased due to GGP, and land use change mainly occurred from 2000 to 2005; (2) the increase of vegetation NDVI value induced because of land use change from 2000 to 2010 in Luohe River Basin, and the increase rate of vegetation NDVI in farmland changing area was higher than that in the unchanged area; (3) both rainfall erosivity and GGP implementation have the significant impact on soil erosion. The increase of soil erosion in Luohe River Basin during 2000—2010 mainly resulted from the increase of rainfall erosivity. If rainfall erosivity keeps constant, then soil erosion in the basin would decrease because of the effects of GGP on soil erosion.
