峨眉山冷杉衰亡原因的初步研究

A preliminary research on the dieback of Abies fabri in Emei Mountain

本文是对峨眉山冷杉衰亡原因的多学科综合考察结果,研究结果表明,峨眉山冷杉衰亡与毁灭性病虫害以及土壤、植物中Al的含量没有明显相关,但与沼泽化程度关系极为密切。峨眉山金顶附近的酸性降水,促进了泥炭藓的生长和沼泽的发展。

In this paper, the dieback reasons of Abies fabri in Emei Mountain were interdisciplinarily investigated. Results show that the dieback of A.fabri trees is not significantly related to the aluminium content of soil and plant and destructive disease and insect pests, but is in close relationship with the development of swamp under the forest. The acid rain near Jinding, the top of Emei Mountain, can accelerate the growth of acidophilous moss and the development of swamp.
