一、綠化事业的重要性及北方园林绿化的发展现状
园林绿化事业是一项功在当代、造福子孙的千秋大业,通过植树造林、载花种草、建设绿色宝库、使其构成完整的绿地系统和优美的景观,以达到净化空气、防止污染、调节气候、保持水土、涵养水源、改善生态等目的。
我国北方幅员辽阔,面积约454万平方公里,差不多占整个国土的一半,这一地区地形复杂,气候万千,东北、内蒙古东部森林密布,资源丰富,其面积和蓄积量均居全国之冠,是我过木材生产的重要基地,其他省区林地稀少,覆盖率较低,又是迫切需要扩大森林资源、改善生态环境的地方。北方森林资源的特点决定了这一地区林业的发展方向。但随这森林被大量采伐利用,北方主要林区正面临着森林资源枯竭,后备资源不足的危机局面,而一些无林和少林地区的造林成效又不十分显著,大面积的荒山荒地荒滩急待造林绿化,水土流失、土地沙化碱化、旱涝灾害等还相当严重。……
