摘要
青藏高原多年冻土地区公路建设项目的生态环境影响主要表现为因冻土退化而造成的一系列生态环境破坏。文章利用“建设项目——生态环境要素”矩阵,在分析公路建设施工期和运营期各工程项目生态环境影响的基础上,得出青藏高原多年冻土地区公路建设生态环境影响关键因子为:植被、野生动物及其生境、自然保护区、湿地、水土流失和冻土层。
Ecological environmental impacts of highway projects in permafrost areas of Qinghai-Tibet Plateau are mainly demonstrated as a series of ecological deteriorations resulted from permafrost degradation. By means of 'engineering item-ecological environmental element' matrix, and on the basis of analysis of ecological environmental impacts caused by different items during highway construction and highway operation, it is concluded that key ecological environmental impact factors of highway projects in permafrost areas of Qinghai-Tibet Plateau are vegetation, wild animals with their habitats, natural reserves, wetlands, soil erosion and permafrost.
