摘要
以平顶山市2009年的森林资源二类调查数据为基础,分析估算了平顶山市森林植被净化大气污染物的能力。结果表明:平顶山市森林植被每年吸收SO2、氮氧化物、氟化物和粉尘的总量分别为1.745万t、7.398万t、0.087万t、0.202万t,略高于氮氧化物和粉尘的排放量,而远远低于SO2的排放量(9.652万t);森林植被对大气主要污染物的净化量以人工阔叶幼林为主,净化量在空间分布上与森林面积和蓄积量一致。
Based on the second-class investigative data of forest resources in 2009 in Pingdingshan city, this paper analyzed and assessed the function of forest vegetation in purifying atmospheric pollutants in this city. The results showed that the yearly quan- tity of SO2, NOx, fluoride, and dust purified by forest vegetation in Pingdingshan city was 17450, 73980, 870 and 2020 t, respec- tively, which was slightly higher than the emission load of NOx and dust, but was far lower than the emission load of SO2 (96520 t) ; the young broad-leaved plantation forest played a main role in the purification of atmospheric pollutants by forest vegetation ; the pur- ification quantity had the same spatial distribution as forest area and forest stand volume.
