对西气东输工程建设扰动破坏原地貌和植被面积、产生的弃土弃渣量、造成的水土流失总量及其危害等进行了科学预测和分析评价。其结果表明,工程建设扰动破坏原生地表总面积达8453.37hm2,损坏水土保持设施面积7766.12 hm2,产生的弃土弃渣总量1140.01万 m3,水土流失总量824.377万t。该研究成果为合理布置各项防治措施,有效地防治工程建设造成的水土流失提供了科学依据。
The prediction and analysis of the disturbance of the original landform and vegetation area, the amount of spoil and spoil generated, the total amount of soil and water loss caused and the damage caused by the disturbance of the construction of the West-East Gas Pipeline Project were carried out. The results show that the disturbance caused by disturbance of the project construction covers a total area of 8453.37hm2, the area of soil and water conservation facilities damaged is 7766.12 hm2, the total amount of spoil and spoil produced is 11,401,000 m3, and the total amount of soil and water loss is 8,243,777 tons. The research results provide a scientific basis for rational arrangement of various prevention and control measures and effective prevention and control of soil and water loss caused by construction.
