宝天高速公路沿线地表水环境现状评价的密切值法

以宝天高速公路为背景,讨论了公路建设对水体环境的主要影响,并利用改进的密切值法对公路沿线地表水进行水环境质量现状评价.通过评价表明:沿线地表水质量良好,基本达到地表水环境Ⅰ级标准;评价结果真实地反映了天宝高速公路沿线水体水质的基本情况,说明采用密切值法对水体进行评价是可行的;该方法概念清晰、计算简便实用,能较好地反映区域内各水体水环境质量的相对优劣,可为制定环境规划、进行环境决策、实施环境综合整治提供科学依据.

Surface Water Environment Quality Assessment of Baoji-Tianshui Freeway by Modified Osculating Value Method

Taking Baoji-Tianshui freeway as the background, this paper discussed the main influence of water body on the highway construction environment. The modified osculating value method was used to carry on the water environment quality assessment along the highway. The results of the assessment indicate that the water quality belongs to the class standard and also actually reflects the basic circumstance of the water. So it can be explained that the modified osculating value method is feasible to the water environment quality assessment, for the conception of the method is clear and the calculation is easy and practical. The method can well reflect the water quality and provide the gist to environmetal programming, environmental decision-making and the environmental repairing.
