摘要
一、前言我国的酸雨污染问题不仅是当今严重的环境问题,而且已威胁着某些地区的森林生态系统,西南地区尤为严重。以重庆为例,1983和1984年所降雨水的pH值平均为4.07,已接近欧洲的污染水平。近年来重庆市南岸和南桐矿区塔山的马尾松纯林,由于受酸雨影响,已出现生长衰退,次期性害虫猖獗发生。
This paper describes the acid rain damage on pinus massoniana and its relationship with the rampancy of periodical pests such as Ips spp. in heavy acid rain areas of Chongqing and Guizhou in southwest China.It could be observed in these areas that the higher acidity of rain results in the greater rampancy of periodical pests and heavier damages on pinus massoniana.
