我区历来造林中,杨树已占绝对比重,而当今更发展为几乎是清一色的杨树,这种倾向值得注意。由于林业生产的长期性、连续性,更需要长短结合,从长计议,以发展的眼光,战略的高度来研究探讨这一问题,以免造成失误,带来损失。以下仅就杨树在造林中的地位,单一发展杨树带来的问题和今后发展杨树的意见进行一些初步的探讨。 In our afforestation, poplar has accounted for the absolute proportion, but nowadays more development is almost all-new poplar, this tendency is worth noting.

The following only on the status of poplar in afforestation, poplar single development problems and the future development of poplar some preliminary discussions.
