- Abstract:
-
Based on the GIS and RS, the soil erosion was analyzed around the Yuka mining area of Qinghai Province. Meanwhile, the coupling relationship between erosion, erosion styles and land use were analyzed by using superposing analysis method. The results show that: most of soil erosion took place in the study site was characterized as wind erosion, as well as a little water erosion. As for the soil types, gray-brown desert soil, alpine desert soil were mainly suffered strong wind and water erosion; alluvial soil were mainly suffered strong wind erosion; strong water erosion occurred in alpine desert grassland soil. As for the land use types, extreme intensive and severe wind erosion mainly happened in the sandy land and gobis, and intensive water erosion occurred mainly in swamp and channel land use types. The ecological characters in this area were fragile with serious soil loss, poor soil fertility and lowest biomass production, and were hard to be restored once vegetation was destroyed. Therefore, the management measures should take soil and land use erosion character as first consideration. And based on this, effective protection measurements should be established to control the soil and water loss and realize the sustainable environment and economic development in this area.
