西气东输管道工程宁夏段水土保持生物植被恢复措施研究

西气东输管道工程东西向横贯我国中部,沿线地貌复杂多变,工程建设易造成植被破坏,水土流失,沙漠化加剧,因此采取相关的生物植被恢复措施防治水土流失和环境恶化十分必要。就西气东输工程宁夏段的建设引发的水土流失及环境问题,在对项目区气候、地形、土壤条件等因素的综合考察分析的基础上,分2大地类,6个立地类型,提出了相应的水土保持生物植被恢复措施,进行生态恢复与重建。该项研究对于创建西气东输绿色管道、生态长廊,保证管道安全和区域生态环境安全有着重要意义。

Study on Vegetation Recovery Measures of West-to-East Gas Pipeline Project in Ningxia

The West-to-East Gas Pipeline Project goes across the middle of China and suffers various complex landforms along the pipeline.The project construction has caused plant deterioration,soil erosion and desertification.Therefore,it is necessary to take vegetation recovery measures to prevent and control soil erosion as well as environment deterioration.In this study,we divide the construction area into two land types and six site types on the basis of synthetic analyses of the factors such as climates,topographic forms and soil conditions.To solve the soil erosion and environment problems in the Ningxia region raised by the West-to-East Gas Pipeline Project construction,we present soil and water conservation and vegetation recovery measures to resume and rebuild the ecosystem,which has a great significance not only to build the west-to-east green corridor and ecology belt,but also to ensure security of pipe and ecosystem.
