玉树与青海主网联网工程植被保护研究与应用

玉树地区发生地震后,当地的电力设施受损严重,加之随着经济社会的发展,社会用电量不断增加,玉树联网工程的建设不仅可解决玉树地区的用电问题,同时可将丰水期玉树地区富余的水电外送。然而该工程穿越三江源腹地,工程沿线生态环境极其脆弱,一旦破坏将很难恢复。针对工程建设的特点,提出了建设中采取拦挡隔离、铺设钢板、草皮剥离养护等植被保护措施,以及施工结束后植被恢复过程中的草种选择、搭配比例、后期抚育等相关要点,为保护高原生态环境提供了技术支撑。

Research on Vegetation Protection for the Yushu Power Grid and Qinghai Main Power Grid Networking Project and its Application

The Yushu power grid and the Qinghai main power grid networking project passes through the central region of the orient of the Three rivers of very fragile ecosystem. Against the project＇ s peculiarity, this paper proposes measures to protect the vegetation along the power transmission line, including isolating, laying steel, turf stripping maintenance and others, and important attention matters for vegetation recovery after the project finish, such as grass seed selection, mix ratio, later tending and etc.
