生态脆弱地区管线建设生态环境影响研究

管线施工对西北干旱、半干旱地区的沙漠、荒漠等生态脆弱地区的生态环境,可能造成不可逆转的影响和破坏.应用遥感、野外样方调查等方法,通过对比＂陕甘宁气田-银川天然气管线工程＂管线两侧建设前后植被类型、土地利用和土壤侵蚀等因子的变化特征,对生态环境自然演替规律和工程建设的影响程度进行了研究,结合管线施工中采取的措施,提出了对生态环境保护的改进方向.

The impact of the pipeline construction on fragile ecologi- environmental area

The engineering of huge scale gas pipeline construction with the development of the West Gas to the East Project has been making irreversible impact and damage on surrounding fragile ecologic-environment of the drought and semi-drought deserts and used lands in the Northwest Region of China. With the techniques of remote sensing and sampling on spot, the characteristics of the vegetations, land utilizations and soil erosions,before and past engineering, along the both sides of the pipeline of the project namely Shaanxi-Gansu-Ningxia Gas Field to Yinchuan Gas Pipeline Engineering Project are comparatively studied. Considering the adopted measures during the engineering, some improved measures are put forward for the ecological protection and restoration in the related area.
