摘要
本文通过对河套灌区小美旱杨贮盐浓度和生物量的研究,推求其采伐可带离灌区的盐量。主要结论为:尽管小美旱杨防护林采伐时可带走一部分盐分,但对于灌区盐分平衡的作用是非常小的,可以忽略不计。
The salt ions content and biomass of Populus simonii × ( Populus pyramidalis + Salix matsudana) cv. Poplaris shelterbelt were studied, the salt ions content of fell in the Hetao area was calculat.d. The conclusion is: felling shelterbelt can decrease saltness, but it does not influenced salt balance of Hetao area.
