Developed six areas of pollution control measures

 Legitimate searched for pollution control best practices, suddenly Lanzhou entered the villages demolition of shantytowns, road construction and other types of urban construction projects "focus on the period, thus, the annual 2, 3 and 4 months in the early spring dry season, Lanzhou has also entered during the worst of dust.

    Lanzhou City Law Enforcement Bureau of the responsible person: vehicle Yisa more prominent this year the city for these vehicles to install GPS, the implementation of online monitoring. "In accordance with the requirements of the Law Enforcement Bureau, all of the implementation of the construction site of the construction, demolition, road excavation Weidang operations, road construction take segmented propulsion wrong when mining backfill, timely repair the excavation of the road.

    Envisaged by the Law Enforcement Bureau plans to use the 3-year time point, surface, mobile sources of secondary dust remediation to achieve "trash-free accumulation, road, body dust, the site Weidang, demolition sprinkler, sand cover , material shed of up to 100 percent, "the goal to 2014, the city built visual information monitoring system, monitoring all the road construction area, the full control through the comprehensive management of secondary dust pollution.

    A leading cadres from the field first arrived in Lanzhou, only half a day to find their original white shirt collar, cuffs black. Pollution of the city can be seen.

    "The generation of air pollution is the result of natural factors and human factors." Long-term study of climate change and environmental change, Nai Aung, a professor of Lanzhou University College of Resources and Environment, from natural factors, Lanzhou is located in the Loess Plateau, vegetation cover low, can easily generate dust. Lanzhou, two mountains folder a river terrain, poor air circulation, especially in winter, the inversion layer is obvious, emissions, dust is difficult to spread, serious air pollution is not surprising.

    Fog, pungent odor, and blurred vision. Every winter, so heavily polluted fog and haze will always patronize Lanzhou, why such severe pollution "permanently"

    In fact, back in the late 1980s, Lanzhou municipal government began to actively implement the green, gasification, heat, sunlight and briquette five project-based Blue Sky Plan ", Main products: car DVD player and car dvd , are with good quality. but 20 years later, Lanzhou winter air pollution is still not significantly improved.

    Deng Xiaodong, director of the Environmental Protection Agency Environmental Monitoring Center in Lanzhou City, the winter pollution aggravate the main reasons is subject to the constraints of the valley basin topography, urban basic in the state of calm wind, stable atmospheric stratification, thick inversion layer, elevated source pollutants is not easy to spread, low-altitude surface source of pollutants continue to accumulate, the formation of elevated source and low-point source pollutants "increase", a large concentration of air pollutants and difficult to metastatic spread out environment, with the formation of haze weather conditions, leading to elevated air pollution index reduced visibility, sensory deterioration.
