| 摘 要： | 全长283.3km的吐乌大高等级公路跨越2个不同的气候区、4个地质地貌单元和8个结构、功能各异的生态区段。公路建设和运营对生态环境的影响主要表现在四个方面：植被的损坏，不同生态小区受损类型和程度不同；某些动物种群栖息地缩小，主要发生在鸟类的迁徙通道上；土壤理化性状的变化和风蚀；对原有人群的生产与生活的干扰，其中包括土地利用方式、畜牧业转场路线和生活、办公场所的搬迁等。在评价生态系统自然恢复难易程度的基础上，文章提出一些人为缓解和恢复对策。

| Abstract: | The Turpan-Urumqi-Dahuangshan Highway, with a total length of 283.3km, crosses 2 climatic regions including 4 different geologic and geomorphic units and 8 small ecological sections of varying structures and function. The study results show that the 4 main negative impacts from construction and use of the highway on eco environment are as:(1)Damage to wood trees and desert vegetation, with the varying impact types and degrees over the different ecological sections; (2) Reduction of the habital of some animals, primarily migratory birds; (3)Change of physical and chemical properties of the soil as well as soil erosion; (4)Disturbance to the human production and well being, including change of land use such as variation of livestock migration routes and the relocation of residential areas and pubulic buildings and so on. This paper, on the basis of assessing the difficulty for natural recovery of the above ecosystems, puts forward some suggestions and countermeasures for artifically rehabilitating and improving the damaged ecosystems. |
