建国以来,我省在造林工作上取得了较大的成就,为今后的造林工作奠定了良好的基础,但从现有的人工林生长情况看,还存在一些问题。如树种单一、造林密度太大,造林技术措施针对性不强。其结果是:幼林成活率、保存率低,林木生长缓慢,不能预期向国家提供木材和林副产品以及发挥应有的防护效能。要提高造林质量,加快造林速度,在造林前要对宜林地进行调查设计,要正确地划分宜林地的立地条件类型,这样才能根据自然条件的特点,有针对性地落实造林六项技术措施。
Since the founding of the People’s Republic of China, our province has made great achievements in afforestation and laid a good foundation for afforestation in the future. However, there are still some problems existing in the growth of existing afforestation. Such as single tree species, afforestation density is too large, afforestation technical measures targeted. As a result, the survival rate of young forests, the low preservation rate and the slow growth of trees can not be expected to provide timber and forest by-products to the country and give due protection. To improve afforestation quality and speed up afforestation, we should conduct surveys and designs on Yilin before afforestation. We should correctly classify the site types of Yilin land so that the six technical measures for afforestation can be targeted according to the characteristics of natural conditions.
