Description of surface environmental characteristics
Surface water is sufficient / dry and dry.
Vegetation: Widely desert,Vegetation sparse.
Soil:The nature of the soil.
Causes of desertification
Deep inland, rare precipitation, weak water, the river underdevelopment.
Vegetation scarcity, poor soil development, flat and loose loose sandy sediments.
From the winter wind source near the wind and more days and concentrated in the dry season in winter and spring, conducive to sand activities.
Temperate continental climate, temperature, precipitation variability / climate anomalies make the ecological environment imbalance, the surface easy to sand.
Latitude is high, the second half of the sunshine a long time, evaporation strong.
Population surge, excessive use of land resources, water resources and unreasonable use, overgrazing, excessive reclamation, excessive firewood, improper irrigation.
Remind:Desertification performance
Desertification of land
Rocky desertification
Secondary salinization
Measures to Combat Desertification
Rational use of water resources.
Use biological measures and engineering measures to build a protective system.
Adjust the land use relationship between agriculture, forestry and animal husbandry.
Take comprehensive measures to solve the energy problems in agriculture and pastoral areas.
Take comprehensive measures to solve the energy problems in agriculture and pastoral areas.
Keep stubble, snow moisture conservation.
