摘　　要：大气污染条件下马尾松针叶营养元素变化的研究张萍，杨光滢，李柏忠关键词大气污染，马尾松，营养元素大气污染条件下森林衰亡的研究，自７０年代中期以来为国内外学者所重视［１～３］；对酸性降水与马尾松林衰亡的研究指出，酸雨、酸雾等酸性降水，加上ＳＯ２等酸性干沉...A comparison was made between a masson pine stand under atmospheric pol-lution with the one in a normal area and the content of needle nutritional elements(N,P,K,Na,Ca,Mg,Mn,Zn,Cu,Fe)of masson pine.P,K deficiency in needles in air pollution areaare significant,but Fe in needles in pollution area is five times as much as that in the normalarea.The mean needle length of masson pine in pollution area is shorter than that in the nor- mal area and the percentage of yellow needles is higher.The productivity loss is about 50%by preliminary assessing.

关 键 词：大气污染 马尾松 营养元素
