摘要
当今,大量人口生活在城市内,空气质量水平是衡量人居环境优劣的重要评估指标。人居环境所享用的清洁空气或大气环境是一个没有边界、没有分割的统一体、连续体,更是人类生存发展的公共资源,空中漂浮物等污染物质的跨边界流动是大气污染、雾霾扩散的最显著特征。其中,来自城市交通拥堵、车辆排队现象越来越突出。本文旨在研究典型路段移动污染源的浓度场分布规律,提出基于移动策略的移动污染源监测方案,通过检测车的实测值与MOVES模型的计算结果对比显示,污染物浓度值在车速速度较慢时,对比结果较一致。从而说明移动监测方案在一定车速范围内的有效性,提高街道区域环境检测的效率,从而为研究城市道路环境、人居环境提供理论方法支持。
Today, a large number of the population lives in cities, the level of air quality is important assessment indicators to measure environmental merits of the Habitat. Habitat enjoy clean air environment or atmospheric environment and which is a no borders, no partition of unity continuum, more public resources for human survival and development, cross-border flows of air pollutants floats is the most significant air pollution and Haze diffusion characteristics. Urban traffic congestion, vehicle queuing phenomenon are becoming prominent for urban development, this paper aims to study the distribution of concentration of mobile sources on typical segment, it provides a method of mobile monitoring for detection of mobile sources, comparing the detected result with that of model of MOVES show that concentration value exhibit high degree of fitness, which descript the effectiveness mobile monitoring under certain speed and the support for urban road environment, human environmental studies a theoretical method.
