- Abstract:
- The construction region of oil-gas field pipeline and its supporting facilities, which located in Chongqing and Sichuan province was selected as the study area. Nine projects of natural gas pipeline were selected and 4 projects with different pipeline types were screened, 24 typical monitoring sites in the project were set. On-site monitoring methods was used to examine the amount of actual soil erosion, the USLE soil and water conservation forecasting model was used to predict the amount of soil erosion. After getting the experimental data, the relation of the observed data and forecast data were fitted by using SPSS software. five factors of the USLE soil and water conservation in the prediction model were selected as the significantly affecting factors. And the mobility matrix analysis on these five factors was carried out. The results showed that: (1) predicting amount of soil erosion form USLE soil and water conservation forecast model equation for the construction process of oil and gas fields in the Sichuan—Chongqing region and field monitoring of the amount of soil erosion fitted very well with the practicality of the actual construction operations; (2) the significance of the impact on soil erosion factors were in the order of soil erosion factor > vegetation cover factor and the rainfall erosion factor > erosion control factor slope factor in terms of the degree of influence priority.
