| 摘 要： | 在1993年的春季和秋季对厦门地区重要的致酸物质天然排放源排放的主要物质进行了大规模的通量观测,并根据通量观测结果用重量面积法估算了该地区天然致酸物质的年排放量?结果表明:厦门地区天然致酸物质的排放主要以硫化物和有机物为主,硫化物主要来源于海滨泥滩和水田,总排放量达2090.2t/a(以硫计);氮氧化物的排放主要来源于水田,总排放量达266.96t/a(以氮计);马尾松和木麻黄的有机致酸物排放量相当可观,分别可达2831.1和423.8t/a?

| Abstract: | The emission fluxes of important acid forming compounds from main natural sources in Xiamen area were measured in the spring and autumn of 1993, and their annual emissions in this area were estimated by using weight area method according to the fluxes. It is shown that sulfur compounds and organic compounds are the main natural acid forming compounds in Xiamen area. Sulfur compounds mainly come from tidal swamp and rice field, 2090.2 t/a (S); nitrogen oxides mainly come from rice field, 266.96 t/a (N); amount of organic acid forming compounds emitted from mainly two species of trees, is verg high and reachs 3254.9 t/a. |
