风景区隧道施工粉尘对大气环境影响评价研究

为了评价风景区隧道施工粉尘对大气环境的影响程度，结合雪山梁隧道施工实际，采用现场测试的方式研究施工粉尘在隧道内的浓度及分布规律，并估算出隧道施工粉尘排放量和粉尘影响区域的大气环境容量，进而通过比较两者大小得出评价结论：雪山梁隧道施工对黄龙景区大气环境的影响十分有限。研究成果可为类似风景区隧道施工大气环境影响评价提供参考。

Atmospheric Impact Evaluation for Tunnel Construction Dust in Scenic Area

In order to evaluate the impacts of tunnel construction on atmospheric environment in scenic area ,field test for construction dust has been conducted in this paper ,combined with the construction actual condition of Xueshanliang tun-nel .Construction dust concentration and distribution in the tunnel has been tested ,dust emissions of tunnel construction and atmospheric environmental capacity of dust effect area has also been estimated according to test results .The evalua-tion conclusion are atmospheric environmental effect of the Huanglong scenic area caused by Xueshanliang tunnel con-struction is very limited by comparing the dust emissions and atmospheric environmental capacity .The research results can provide reference for the atmospheric environmental impact assessment of tunnel construction in similar scenic areas .
