新华社西宁８月１７日电（记者 骆晓飞 文贻炜）针对三江源地区生态环境脆弱且遭到破坏后极难恢复的现实难题，青海省公路建设部门在三江源地区第一条高等级公路——共和至玉树公路建设过程中，创造性地提出“无痕迹施工”理念，采用草皮移植养生、复植以及人工补种等多种措施恢复施工沿线植被，不仅有效保护了生态环境，而且减轻了公路今后的养护成本。

    Xinhua xining August 17（Reporter LuoXiaoFei WenYiHui）According to the fragile ecological environment in the source region and destroyed very difficult to recover after the reality of the problem，Qinghai province highway construction department in the source region article first highway - the republican to yushu in the process of highway construction，Creatively put forward“No trace construction”concept，The turf transplantation keeping in good health、Recultivation and artificial resow and so on the many kinds of measures to restore vegetation construction along the line，Not only effectively protect the ecological environment，And reduced the highway future maintenance cost。

    “所谓‘无痕迹施工’，就是要实现‘在公路建成后，公路沿线看不到施工痕迹。’” 青海省玉树至共和公路建设指挥部副指挥长纳启才说，通过投入巨额环保资金，科学规划和认真落实草皮移植、人工种草、湿地保护和动物生存环境保护等各项生态环境保护措施，共和至玉树公路建成后，将是一条真正的“环保路。”

    “The so-called‘No trace construction’，Is to realize‘After the completion of the highway，Along the road to see construction trace。’” Qinghai province highway construction headquarters to yushu republican vice ZhiHuiChang nano rev. Just said，Through the investment huge environmental protection funds，Scientific planning and earnestly implement turf transplantation、Grow grass artificially、Wetland protection and animal survival environment protection and so on each ecological environment protection measures，The republican to yushu highways are built，Will be a real“Environmental protection way。”

    纳启才介绍，共和至玉树公路建设伊始，项目建设指挥部就组织编写了《环境保护施工标准化指南》。根据这一标准化指南，施工营地被选择在没有植被或植被稀少的地方，全线２７０公里适合草皮移植的路段全部进行草皮的养生移植，而对于沿线土地沙化严重、无法移植草皮的地段，路基平整完成后，则全部根据当地的地质条件和气候条件进行人工种草。

    Nano rev. To introduce，The republican to yushu at the beginning of the highway construction，The project construction headquarters will write the organization《Environmental protection construction standardized guidelines》。According to the standardized guidelines，Construction the camp was selection in no vegetation or vegetation sparse surroundings，The 270 km for turf transplantation all sections on the turf health transplantation，For serious along the land desertification、Can't transplantation of turf，After completion of subgrade flat，All is according to the local geological conditions and climate conditions are artificial planting。

    “根据相关施工标准，共和至玉树公路建设过程中每公里环保投资超过４０万元，全线１７个标段、６３４公里路段的环保总投资将达到３亿元，占工程总投资的近３％。”

    “In accordance with the relevant standard of construction，The republican to yushu in the process of highway construction per kilometer environmental protection investment more than 400000 yuan，All 17 section、634 kilometers of road environmental total investment will reach 300 million yuan，Accounts for nearly 3% of the total project investment。”

    据了解，目前，共和至玉树公路已经完成草皮移植和人工种草１５０万平方米，且成活率均接近１００％。而全线贯通后，有效保护和恢复的草地面积将达到２２０万平方米。

    It is understood，At present，The republican to yushu road has been completed turf transplantation and grow grass artificially 1.5 million square meters，And the survival rate is close to 100%。And after all through，Effective protection and restoration of grassland area will reach 2.2 million square meters。

    青海三江源地区是黄河、长江、澜沧江的发源地，这里独特的生态环境造就了世界高海拔地区独一无二的湿地生态系统，被誉为“中华水塔”。于２０１１年全面开工建设的共和至玉树公路是这一地区的第一条高等级公路，公路全长６３４公里，其中大部分路段穿越三江源自然保护区。

    In the source region of the Yellow River in qinghai province is、Yangtze river、The origin of the lancang river，Here the unique ecological environment of high altitude area makes the world unique wetland ecological system，Is regarded as“The water tower”。In 2011 fully operative construction of the republican to yushu road is the area the first high grade highway，634 km of road，Most of them through three sections of nature reserves。
