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.
