近年来,随着交通事业的发展,高等级公路的修建日渐增加,这对周围环境的影响也逐渐加重.因此在高等级公路的可行性研究及设计中增加了环境评价这个项目,目的是为了减少公路对周围环境的不利影响,使之与自然环境相益得彰,融为一体,进而起到妆点江山、美化和改善环境的作用.环境评价包括噪声、大气、水、土壤、景观等对环境的影响评价.但噪声、大气、水、土壤的影响都可以用物理或化学的指标作为评价的标准,而景观很难用数字进行直接的定量.景观的最终评价是由人们的视觉来进行.因而
In recent years, with the development of transportation, the construction of high-grade highways has been gradually increasing, and the impact on the surrounding environment has also been gradually aggravated. Therefore, the project of environmental assessment has been added to the feasibility study and design of high-grade highways for the purpose of Reduce the adverse impact of the highway on the surrounding environment, make it compatible with the natural environment, and then integrate and play a role in beautifying and improving the environment. Environmental assessment includes noise, atmosphere, water, soil, landscape, etc. Environmental impact assessment.But the influence of noise, atmosphere, water and soil can be used physical or chemical indicators as the evaluation criteria, and the landscape is difficult to quantify directly with the number.The final evaluation of the landscape by the people’s vision So
