The wind erosion and soil nutrient change of the pipe engineering of transfer natural gas from the west to the east in the west section of Shaanxi Province are monitored and analyzed.It showed that the lengths of pipeline through agricultural land,forestry,grassland amount to 60.8%,22.6%,and 9.6% respectively.The pipe eng-ineering could increase the wind erosion and worsen the soil nutrient.The wind erosion in engineering area on the stable and sem-istable sandy land is as double or triple times as that on site without disturbance by construction.During construction,the soil organic matter,total nitrogen and total phosphorus in the surface soil decrease by 30% to 40%,and the soil moisture decrease by 25% to 35%.
