| 摘 要： | 为研究管线建设对中低山区生态环境的影响，通过定量预测川陕天然气输气管线建设对大巴山土地利用与农业生产、植被面积与生物量、土壤侵蚀及生态系统完整性产生的影响，对管线建设可能引起的中低山区生态环境的改变进行了分析。结果显示，虽然管线建设会使区域土地利用结构发生变化，从而对当地农业生产造成一定影响，并使植被面积及生物量有所降低，使土壤侵蚀量有所增加，但这些影响主要集中于建设期，多数是暂时的，可恢复的，基本不会改变中低山区原有生态系统的完整性，生态系统仍然具有完整的结构和连续不断的运行过程。

| Abstract: | To study the impacts of pipeline construction on eco-environment in the middle-low mountainous area,the quantitative prediction is made for the changes of landuse,agricultural production,the area and biomass of vegetation,soil erosion,and ecological system integrity in the Daba Mountains by the Sichuan-Shaanxi natural gas pipeline construction.An analysis of possible influences made to the eco-environment of the middle-low mountainous area by the pipeline construction is then presented.Results show that the construction can change the structure of regional landuse,which can in turn influence local agricultural production,reduce the area and biomass of vegetation,and increase soil erosion.Nevertheless,the influences are temporary and can be alleviated,as they mainly concentrated in the construction period.The environmental effects of the project will not essentially alter the original eco-integrity of the middle-low mountainous area.Therefore,the ecological system remains its complete structure and consistent operating process. |
