| 摘 要： | 根据甘肃甘南藏族自治区的自然环境特征、国道G213线的工程建设特点,分析了G213线改扩建工程对甘南州草原生态环境的影响。结果表明,公路建设施工期对沿线植被的负面影响较剧烈,局部土壤环境受到较大扰动,被扰动的土体侵蚀类型主要是水蚀,扰动后可能造成水土流失量为68866.7 t,新增水土流失量为63 060.5 t。针对项目可能存在的主要生态环境问题(植被破坏、水土流失等),提出了建议措施。

| Abstract: | Based on the natural environmental characteristics of Gannan Tibetan Autonomous Prefecture and construction features of the highway G213,the influence of the highway construction on the grassland eco-environment there is analyzed in this paper.Results show that the negative influence on vegetation during construction periods is severe.The soil environment is disturbed greatly in certain areas,rainfall erosion is the main factor in soil erosion,and the loss volume of soil and water is 68 866.7 t,63 060.5 t of which is the increase.Finally,some proposal and measures are suggested in terms of the probable environment problems in the construction. |
