新疆迪那凝析气田地面工程项目区水土流失关系及预测

Study on Relationship between Dina Condensate Gas Field Ground Project Area and the Soil Erosion and Prediction

根据不同类型建设项目的水土流失特点,采用调查分析法,在现场勘测和分析相关资料、文件的基础上,分析了迪那凝析气田地面工程水土流失与自然水土流失的关系,研究了典型项目区的水土流失,预测了水土流失面积。结果表明,该工程在建设过程中将扰动原地表面积674.02 hm2,损坏水土保持设施造成设施水土保持功能的丧失或者降低的总面积高达674.02 hm2。研究结果为迪那气田水土保持与生态修复提供了科学依据和技术支撑。

According to the characteristics of soil erosion in different types of construction Dina condensate gas field ground project, using the survey analysis method, based on the field survey and analysis of relevant information, docu- ments, the relationship of construction project soil and water loss and soil erosion was analyzed, and the soil erosion of typical project area was studied. Then, the soil erosion was predicted. The resuits showed that the project in the con- struction process would disturbed the surface area of 674.02 hm2, and the damage of soil and water conservation facili- ties caused by the total area of soil and water conservation facilities function loss or reduction of up to 674.02 hm2. The results provided a scientific basis and technical support for soil and water conservation and ecological restoration of Dina condensate gas field ground project.
