| 摘 要： | 测定了长春市不同类型地表汞含量及其释放通量，分析了地表汞释放通量的影响因素。研究结果表明，不同地表土样的汞含量存在很大的差异；煤炭堆放地和沥青地地表汞含量较高，应引起足够的重视。地表汞释放通量受地表汞含量、地表类型、降水、太阳辐射等因素的影响。降水期间或降水后期地表汞释放通量明显增加。可见，地表汞释放是一个动态过程，随时间和空间而变化。 |
| 关 键 词： | 城市 地表 汞污染 释放通量 长春 土壤 |

| Abstract: | Mercury concentrations in surface soil and Hg emission from soil were determined, and factors affected Hg emissions were analyzed. Results indicated that Hg concentration in different surface soil varied greatly, the highest concentration was found in coal-stacked soil, and then the higher in bituminous road, which should pay much attention on. Hg emission fluxes varied with Hg concentration, the different surface type, precipitation and solar radiation, etc. During or after precipitation event, Hg emission flux increased. Hg emission from land surface is a dynamic process, changed with time and sites. |
| Keywords: | mercury urban surface emission flux factors |
