- Abstract:
- To assess the variation of soil wind erosion on the main earth’s surface of Hetian, the quantity of soil wind erosion and some surface properties were concurrently measured and analyzed in 2004.① A decreasing order for the each surface of the quantity of sand transport was the abandoned farmland, the intermediate zone of desert and rural section, the active sand dunes on the edge of the desert, the rural roads, the cottons covered with film and the alfalfa.② With the magnification for space the amounts of sand transport from the Takla Makan desert to other earth’s surface were followed exponential curve law dropping.At the point of 400 m, the amounts of sand transport were declined from 30 g/cm2 to 1 g/cm2, the difference wasn’t too much among every earth surface after the point.③ Under the vegetation covering condition, the uptaking amounts of sand transport of the cottons covered the film and the alfalfa were more than their down tuyering and increased with the sampling height but the abandoned farmland, the intermediate zone of desert and rural section, the rural roads and the active sand dunes on the edge of the desert were more at 20 cm and decreased with the height.The quantity of soil wind erosion was the most and the wind erosion harm degree was also extremely serious in the abandoned farmland, the inter-mediate zone of desert and rural section, the rural roads and the active sand dunes on the edge of the desert.So they were the most potential dust contributors in the area of Hetian.Make some measures to reduce the soil wind erosion and sand storm in Hetian.Such as expanding the winter wheat, planting perennial herb and the green crops, implementing the protective cultivation system, avoiding over-grazing cultivating and laying the rural roads with Gobi, the gravel, the asphalt.
