【摘要】 为了查明粉煤灰绿化林木生长状况及林分郁闭后的防护效果,采用标准地和样方调查方法,调查林木、草本植被及根系生长状况。林内气象数据的采集采用森林气象流动调查的方法。结果表明,在粉煤灰上采用速生旱柳造林绿化树木生长势较好,根系发达,植被增多。森林小气候基本形成,防风降尘作用明显。更多还原

【Abstract】 In order to investigate the growing status of the forested groves on the pulverized fuel ash(PFA) and their environmental protection effects after the formation of canopy density,the standard fields and sampling quads were adopted as the investigating methods.Trees,herbage vegetation and roots were investigated.The meteorologic factors were obtained from the moveable investigation of forest meteorology.The results indicated that on the PFA,the fast-growing Hankow Willow Salix Matsudana grow well on stong roots,resulting in increased vegetation density.Forest microclimate was basically established to effectively control dust and wind.更多还原
