在受到水泥粉尘污染的约３０年生马尾松（ＰｉｎｕｓｍａｓｏｎｉａｎａＬａｍｂ．）、黑松（Ｐ．ｔｈｕｎｂｅｒｇｉＰａｒｌ．）和杉木〔Ｃｕｎｎｉｎｇｈａｍｉａｌａｎｃｅｏｌａｔａ（Ｌａｍｂ．）Ｈｏｏｋ．〕林地，各建立５０ｍ２样地，测定滞尘量，凿取水泥厂投产（１９８３年）前后各６年的木材样品，进行树干解析和有关元素含量的测定。结果表明，水泥粉尘对林木的高、胸径和材积的生长有抑制影响，并使木材中硅、钙、钾、磷含量增加，镁、铁、铝含量减少。这种影响随树种而异。 Approximately 30-year-old Pinus massoniana Lambe, P. thunbergi Parr. And Cunninghamia lanceolata (Lamb.) Hook contaminated with cement dust. ] Woodland, the establishment of 50m2 plots, measuring the amount of dust, chisel cement plant put into operation (1983) before and after 6 years of wood samples for trunk analysis and determination of the relevant element content. The results showed that the cement dust had an inhibitory effect on the height, DBH and volume growth of woods, and the contents of silicon, calcium, potassium and phosphorus in the wood increased, and the content of magnesium, iron and aluminum decreased. This effect varies by tree species.
