Solution of soil erosion
(1) Engineering measures: building terraces, damming and silting land, using earthwork and concrete works, fish scale pits, etc
(2) Biological measures: restoration of vegetation, afforestation, afforestation, return of farmland to forest and grass, etc.
(3) Agricultural technical measures: intercropping, high furrow and ridge planting and other tillage methods, mulch, scientific fertilization, the use of sprinkler irrigation, drip irrigation and other irrigation technologies
(4) Others: prohibit indiscriminate deforestation, improve laws and regulations, and enhance environmental awareness; When mining, it is planned to store topsoil, and vigorously carry out land reclamation work
Solution of soil erosion on Loess Plateau

1. Slope protection:
   ① Engineering measures: build horizontal terraces on gentle slopes and develop forest fruit bases
   ② Biological measures: afforestation and grass cultivation on steep slope, interception and conservation of slope runoff
2. Ditch fixing:
   ① Engineering measures: the main ditch dam construction, mud storage
   ② Biological measures: Build shelterbelts in each branch ditch
3. Protection tableland:
   ① Engineering measures: level the land, increase water infiltration, reduce surface runoff
   ② Biological measures: build a field protection forest network, afforestation mainly with timber forest and fruit forest, and form an ecological agricultural system of forest and grain, fruit and grain intercropping
   ③ Agricultural technical measures: the use of advanced irrigation technology to save and make full use of water resources
