哈尔滨市环境空气分析初报

根据哈尔滨市环境空气监测材料，对主要污染物质及其季节动态和空间分布进行了分析和研究，结果表明，哈尔滨市主要污染物质为二氧化硫、氮氧化物、悬浮颗粒物。其中，二氧化硫以一、四季度较高，空间分布上以道里区、道外区及太平区污染严重，南岗区污染最轻；氮氧化物在供暖期的一、四季度明显高于非供暖期的二、三季度，空间分布上以道里区、道外区污染相对严重；总悬浮颗粒物（TSP）以供暖期及初春秋末污染严重，空间分布上各行政区间差别较小。根据城市污染状况，笔者还对环境空气污染重点问题进行分析，并提出了相应的对策。

The Primary Analysis of Atmospherical Environment in Harbin

The authors analyzed and studied the main pollution compounds and their seasonal dynamic and spatial distribution on the base of the air - monitoring data of Harbin. The results show that the main pollution compounds are sulfur dioxide, nitro-gen oxide and suspension granule. With respect to sulfur dioxide, it comes to the comparatively high level in the first and fourth quarters as well as in Daoli district, Daowai district and Taiping district, and the low level in Nangang districrt. The content of oxidation - nitrogen compounds is higher in the first and fourth quarters than in the rest quarters, it is also higher in Daoli district and Daowai district than in the other districts of Harbin. The whole suspension granule becomes serious pol-lution in the period of heating and at the beginning of spring, but there are no considerable difference in spatial distribution.
