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
- 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 - Ditch fixing:
① Engineering measures: the main ditch dam construction, mud storage
② Biological measures: Build shelterbelts in each branch ditch - 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
