高速公路服务区生活污水排放是服务区对周边水环境影响的主要方式。研究通过现场调查、问卷调查方法,收集了目前高速公路服务区交通量、客流量、生活用水、污水排放量等信息,并应用统计学方法分析了它们之间的关系。结果表明:(1)服务区日均用水量与日均排水量呈现较好的正相关关系;服务区交通量与日均客流量、日均用水量均呈正相关关系;日均用水量随日均客流量的增加而增加,在客流量较小的情况下,日均客流量与用水量线性拟合关系相对较好。(2)不论是基于全部调查数据的回归分析结果还是以交通量划分的两类服务区的回归分析结果,在决定服务区日均用水量的各变量中,服务区工作人员数量对日均用水量的影响大于日均客流量对日均用水量的影响,随着交通量的增加,工作人员数量对用水量的贡献降低。
The discharge of domestic sewage in the service area of the expressway is the main way that the service area affects the surrounding water environment. Through the field investigation and questionnaire survey, the research collected the information of traffic volume, passenger flow, domestic water and sewage discharge of the expressway service area at present and analyzed the relationship between them by using statistical methods. The results showed that: (1) There was a positive correlation between average daily water consumption and daily average displacement in service area; traffic volume in service area was positively correlated with daily average daily flow and average daily water consumption; average daily water consumption was positively correlated with daily average The increase of passenger flow increases. In the case of small passenger flow, the daily average of passenger flow and water consumption is relatively good linear fit. (2) The regression analysis results based on all the survey data or the regression analysis results of the two types of service areas divided by traffic, among the variables that determine the average daily water consumption of the service area, the number of service staff in the service area is significantly lower than the average daily water consumption The impact of volume is greater than the average daily volume of water on the impact of traffic, with the increase of traffic, the number of staff to reduce the contribution of water consumption.
