| 摘 要： | 以青海地区的公路建设为例，阐述在西北高寒地区公路建设对生念环境的影响。公路建设对生态环境的影响主要体现在三个方面：(1)对土地利用方式的影响；(2)对公路沿线植被的影响；(3)对野生动物的影响。由于高寒地区降雨量少，蒸发量大，生态系统非常脆弱，一旦遭受破坏难以及时恢复，因此在公路建设时必须考虑这些特殊环境，以植被恢复为重点，减轻或消除公路建设带来的不利影响。

| Abstract: | The impact of highway construction on the ecological environment in the high altitude area in Northwest China is expatiated .They are mainly expressed by three parts:(1)the influence on using of the glebe;(2)the influence on vegetation;(3)the influence on the wildlife.In this area,it's lack of rainfall,but it's plenty of evaporation.So,its (ecosystem) is very frailty.And if it's destroyed,it will be difficult to be recovered.The measures must be taken to eliminate or lighten the unfavourable influence. |
