我国“三北”地区建立防护林体系,对改善区域自然环境、恢复生态平衡、促进农、牧业生产的发展,提高人民生活水平,具有十分重要的意义。但是“三北”地区由于气候干旱、雨量少、风沙大、水上流失严重、土地瘠瘦,造林比较艰巨,常常难以达到理想的效果。为了促进“三北”地区造林事业的发展,提高造林成效,笔者根据在辽西干旱(半干旱)地区多年造林研究工作和研究成果,结合在生产中的经验,对干旱地区造林几项技术问题,提出一些看法,以供生产上参考。
The establishment of the shelterbelt system in the “Three Norths” of our country is of great significance to improving the natural environment in the region, restoring the ecological balance, promoting the development of agriculture and animal husbandry, and raising the living standards of the people. However, the “Three Norths” regions are often struggling to achieve the desired results because of the arid climate, less rainfall, large sandstorms, serious water loss, poor land, and arduous afforestation. In order to promote the development of afforestation in the “Three North” regions and improve the afforestation effectiveness, based on the years of research and achievements in afforestation in the arid (semi-arid) area in western Liaoning and the experience in production, the author analyzed several technical issues concerning afforestation in arid areas, Put forward some views for the production of reference.
