The Effect of the Gully Land Consolidation Project on Soil Erosion and Crop Production on a Typical Watershed in the Loess Plateau

摘要: The Gully Land Consolidation Project (GLCP) was launched to create more arable land by excavating soil from the slopes on both sides of gullies, combined with simultaneous comprehensive gully prevention and control measures. purpose GLCP is increase crop production reduce erosion achieve ecological agricultural sustainability. In this study, we assess effects studying BaoChengGou Watershed in Loess Plateau, primarily means high spatial-resolution satellite images (taken GF-1 ZY-3 satellites) InVEST model field investigations. Sloping cropland, sparse forestland, natural grassland are main use types study area. After implementing GLCP, consolidated cropland increased 7.35%, an that has come largely at expense forestland. markedly reduced Watershed, especially sense intensity also significantly project region whole, despite intensifying certain places, such as excavated slopes; furthermore, it improved yields area 10.9%. Comprehensive measurement shows be scientific, reasonable, clearly efficacious. This presents findings regarding positive significance promoting sustainability Plateau.
