Measures to control soil erosion in the Loess Plateau include soil and water conservation and comprehensive management. Principles of soil and water conservation: adjust the structure and layout of land use and combine management with development. The basic measures are: agricultural land, using modern agricultural technology, building drought and flood to ensure harvest, and compressing high and stable yield farmland. Expand the area of forests and grasslands. Protect and improve natural grassland and reasonable grazing density. Open pit mining, timely backfilling and reclamation. Objective: To improve the environment, increase vegetation coverage and prevent soil erosion. Comprehensive management of key small watersheds: soil and water conservation, and establishment of efficient production system of agriculture, forestry and animal husbandry. Meaning: saving water and helping the poor. Action: Take measures such as engineering, biotechnology and agricultural technology together to combine complementary interests.
