摘 要：
燃煤电厂排放的灰渣是以灰场贮存为主,在多风季节,大量表层干灰随风飞扬,造成二次污染,严重污染周围生态环境,危害居民健康。为治理污染,采用5种宁夏当地乡土树种柽柳和芦草对干灰区进行绿化覆盖试验。结果表明,长穗柽柳成活率高,生长量最大。6~7月份扦插造林成活率高,容器苗在6~8月份移栽成活率高,成本低。长穗柽柳营养钵苗与芦草以株行距80 cm×100 cm,行间混交长势茁壮,覆盖率最高,3年可实现对灰场的绿化覆盖,有效治理粉尘污染。

摘 要：
The ash emissions from coal-fired power plants is mainly stored in the ash field. In the windy season,a lot of surface dry ashes float in the sky,which can pollute environment seriously. Greening coverage on the ash field was carried out by planting several kinds of Tamarix and Phragmites australis(Cav.)Trin.ex Steud.The results indicated that T. elongata Ldeb.grew strongly with high survival rate and increment. The survival rate of cutting forestation was high in June to July. The survival rate of container seedling transplanting was high was high in June to August. Container seedling of T. elongata Ledeb and P. australis(Cav.) Trin.ex Steud. growing strongly and having the highest coverage under the condition of plant spacing 80 cm×100 cm and mixed planting by rows. It could realize greening coverage of on the ash field in 3 years,so as to achieve the goal of effective control of dust pollution.
