The Planning Research Of The Historical Town's Air Environmental

In recent years, along with the industrial rise, the Earth environment was increasingly bad, the ecosystem balance was break severely, the cultural relic material be subjected to terrible havoc.With there is no polluting period compare, the speed that cultural relic break is quicker and quicker, the disaster that face to drown.Although the cultural relic protector adopt many safeguard, prevent further breakages of cultural relic availably. If don't improve the environment quantity of the cultural relic, the repaired still suffers to continuative break probably. The relic of Ancient town are overground all along, so its air pollution is a main factor that results in the cultural relic injure. Among them ,dust, acid rain and gaseous pollutants are most minatory .If we want to resolve the long-term overground relic conservancy problem, we must improve the atmosphere environment.Therefore, the request that look for a set of atmosphere environment programming project that suiteds for the ancient town of our country is very urgently.The air pollution source of ancient town include indoor air pollution source and outdoors air pollution sources ,they are burning coal waste gas mostly.The outdoors pollution source belongs to face source pollution, its characteristics are many quantity, wide face and concentrated control hardly, the indoor pollution source belongs to intermittent pollution source, the pollutant concentration change obviously,and it's serious overrun in the burning coal high peak period.This thesis discussed the breakage mechanism of numerous air contamination to the history cultural relic, taking basic characteristics in ancient town as the basis, selecting typical indoor and outside air pollutants SO₂ and TSP as the object, built up the environment capacity correction model of atmosphere and the concentration correction model of indoor and outside air pollutants for this district respectively. To take Pingle town as an example,verifing these correction models through compute and Verifing applicability of the relation formula for speed material- corrupt with SO2 air concentration also. On this foundation, withcultural relic protection as the target, putting forward the SO2 air quantity propositional standard.This thesis with the second-class standard value of that propositional standard for a programing target, put forward the decisive measure for pingle town's atmosphere environment programming,which can protect the overground cultural relic and delay the air pollution of historical town of China.Thus,the thesis has some reference value.
