随着西部大开发战略的实施,位于青藏高原腹地的三江源区需要建设大量的公路。这难免会对三江源自然生态环境造成破坏,使局部地形改变,这样将会形成许许多多的区域小气候,从而改变动植物的生存条件,严重影响生态环境。公路污染源对生态环境的影响,主要有噪声、废气、废水及固体废弃物等,主要通过对地表植被和土壤结构的破坏,导致
With the implementation of the strategy of developing the west, a large number of highways need to be built in the Three Rivers Source Area located in the hinterland of the Qinghai-Tibet Plateau. This will inevitably cause damage to the natural ecological environment of the Three Rivers and change the local topography. This will result in the formation of many regional microclimates, thereby changing the living conditions of animals and plants and seriously affecting the ecological environment. The impact of highway pollution sources on the environment is mainly noise, exhaust gas, waste water and solid waste, which are mainly caused by the destruction of the surface vegetation and soil structure
