大庆地区空气中总烃与非甲烷烃分布规律研究

分析了大庆地区空气中总径与非甲烷烃的比例关系，年、季、日变化规律及浓度水平。说明了总径与非甲烷径浓度水平在采暖期和非采暖期无显著差别，且冬、夏分布大体一致，高浓度多集中于大庆市东北部，浓度值向西南偏南方向递减，总烃总体浓度冬季较夏季偏向于西南这一规律。讨论了气候条件对分布规律的影响，并指出总烂的主要来源是油田开发和机动车尾气排放。

Research on the distribution patterns of the total hydrocarbon and non-methane in the air of Daqing region

Authors analyzed the relationship of the total hydrocarbon in propor-tion to non-methane in the air of Daqing region and their varying regulations annually,seasonally and daily as well as the concentration value levels. The reserch showed thatthe concentration levels of hydrocarbon and non-methane didn't indicate obvious differ-ences during heating and non-heating seasons,and the distribution patterns of the totalhydrocarbon in winter and summer are basically the same,while the higher concentrationvalues were mostly centralized in the northeast part of Daqing city which decresed pro-gressively southwestward. In general, the higher concentration values in winter werecentralized more southwestward than that in summer. Authors also discussed the effectof climate conditions upon the distribution patterns and pointed out that the mainsources of the total hydrocarbon were the oil field development and emitted vehicletailgas.
