| 摘 要： | 2009年底至2010年初,北京市降雪非常集中且强度较大,为保障交通畅通,大量的氯盐融雪剂在北京城区的绿地上应用,其用量达3万t.路面撒施的融雪剂不可避免地进入分车带、绿化带等绿地,对绿地植物正常生长造成威胁.文章通过实地采集了45个绿地土样,研究了道路绿地土壤盐分等相关指标,结果表明,与对照相比,撒施融雪剂对道路绿化...

| Abstract: | There were several heavy snowfalls during winter of 2009-2010 in Beijing and nearly 30,000 tons of snow melt agent containing chloride salt were used to guarantee the smooth and safe traffic flow.Snow melt agent containing chloride salt inevitably entered the greenbelt soil by the road,which greatly threatened the growth of plants.Soil salt and chloride content were studied and analyzed after typical greenbelt soil samples were collected from main arterial traffic such as the 2nd,3rd and 4th rings road.Resu... |
