仪征—长岭原油管道项目湘赣鄂标段水土保持监测

Soil and Water Conservation Monitoring Practice for the Section of Yizheng——Changling Oil Pipeline Project in Hu’nan, Jiangxi and Hubei Provinces

对仪征—长岭原油管道湘赣鄂标段开展了开发建设项目的水土保持监测工作内容包括:项目基本情况、监测范围及监测分区、监测内容、监测方法、监测结果分析等等。监测结果表明,该工程项目的扰动土地整治率、水土流失治理度、拦渣率、土壤流失控制比等指标都达到了防治标准,但植被恢复指数和林草覆盖率两项指标距预期目标还有较大差距。

The paper introduces the soil and water conservation monitoring practice in the development and construction project of Yizheng-Changling oil pipeline in Hu＇nan, Jiangxi and Hubei Province. The content includes the background of project, monitoring area and its zoning, monitoring contents, monitoring methods, analyses of monitoring data, discussion and conclusion, etc. The monitoring result indicates that the monitoring indices like restoration ratio of disturbed farmland, control ratio of soil and water loss, retaining ratio of discarded earth and stone, and control ratio of soil erosion come up to the standards of prevention and harness. However, the two indices of restoration ratio of destroyed vegetation and coverage degree of forestry and grass have larger gaps for reaching the desired goal.
