在这里我们再来看看美国拉斯韦加斯对沙尘暴的防治。制度管理是当地根治沙尘的一个重要办法。人为因素是该县沙尘问题产生的一个重要原因。比如:有些人喜欢在沙漠上开车,弄得沙尘飞扬;再如:随着拉斯韦加斯的扩建,在沙漠上建房、施工、修路也都可能会引起沙尘问题,如果遇到刮风就更糟了。政府采取宣传加惩罚的措施,一是通过媒体、路牌告示及发放宣传品,告诉人们不要人为制造沙尘。二是对沙漠土地拥有者实行承包责任制。如果沙漠土地拥有者和居住在那里的屋主,不能很好地控制沙尘,将会受重罚,每天罚款500美元,再不执行,每天增罚2000美元。三是对人为制造沙尘者进行电话举报,有举报必处理。四是限制施工单位制造沙尘。对在沙漠中施工的承包单位负责人和职工在开工前至少上4个小时的环境课,让他们在施工中尽量减少灰尘,要求他们一边施工一边用水消尘。如果达不到要求,空气质检部门将勒令其停工或给予罚款。
Let's take a look at the prevention and control of sandstorms in Las Vegas, USA. System management is an important way to eradicate dust. Human factor is an important reason for the dust problem in the county. For example, some people like to drive in the desert and make the dust fly; for example, with the expansion of Las Vegas, building houses, construction and road construction in the desert may also cause dust problems, even worse in case of wind. The government adopts measures of publicity and punishment. First, it tells people not to create dust artificially through media, road signs and distribution of propaganda materials. The second is to implement the contract responsibility system for the owners of desert land. If the owner of desert land and the owner of the house who lives there can't control the dust well, they will be fined $500 a day. If they don't implement it, they will be fined $2000 a day. The third is to report the man-made dust by telephone. If there is a report, it must be handled. Fourth, the construction unit shall be limited to produce dust. The person in charge of the contractor and the staff who construct in the desert shall have an environmental class at least 4 hours before the commencement of construction, so that they can reduce the dust as much as possible during the construction and require them to use water to eliminate the dust while constructing. If it fails to meet the requirements, the air quality inspection department will order it to stop work or impose a fine.
