concrete mixing stations

news dispatch (reporter Deng Qi) recently, Beijing Academy of Social Sciences Institute of economic research released "building Beijing" air system "" research report. The report, Beijing city is the most important tuyere -- Changping Nankou to horse pond area is polluted, causing "increasing haze effect" on the city, should be fully removed the regional pollution industry, construction of "fresh air", the fresh air into the city, thereby reducing haze.

northwest wind maximum

on urban pollution effect

Ding Jun introduced, there are three major wind in Beijing area, the main research topic is the most important northwest wind.Among them, Changping Nankou - horse pond area of Beijing five sandstorm affected areas is one of the largest, air impact on urban air quality. "It is the Urban Haze pollution 'contribution' maximum."

The

report suggests that return tuyere "dust source"

The

report, South Ma Chi Kou is an important source of city air duct system of export, but now the serious pollution. For example, the horse pond area, about 10 square kilometers area surrounding a road within, gathered the asphalt material smelting plant, concrete mixing stations, construction waste slag and the http://www.thepaladin123.com/ sale of coal pit, heavily polluted industrial community.

The

report suggests, polluting activities of the tuyere area of Beijing city are systematically removed, remodeling the tuyere area planning positioning, its location is Beijing "air system" in the "source", "upper respiratory tract", "high quality source library", the establishment of planning and the concept of ecological priority.

"the city and build channel deposit difficulty"

The

report also enumerates some cases city construction ventilation corridor ", Wuhan has built six ecological corridors, constitute the six 'green channel', it makes Wuhan City summer maximum temperature dropped by an average of 1 to 2 DEG C", "German Munich planning and construction of five urban ventilation Road, like install air system to the city, city air quality improvement effect."

this, Ding Jun said, domestic and foreign city construction ventilation corridor to us, "fresh air resources" http://www.bigorange123.com/ is the city micro climate regulation, effective means to improve air http://www.firsttime123.com/ quality, reduce the urban heat island effect difficult to replace. "Beijing Garden Expo Garden Jinxiu Valley is converted by the sand pit. Park is completed, the surrounding particles http://www.xiaoyu566.com/ concentration decreased 60%, the ecological environment governance effect is very obvious. Believe that the transformation of horse pond and the surrounding area will be city haze governance has a more pronounced effect."

for how to connect with urban air duct outlet, said Ding Jun, currently in the city building there is a big difficulty http://www.quicklinks321.com/ duct, can consider to do the peripheral docking planning and air inlet duct, accumulate experience for the transformation of urban air.
