摘要：目前,全球盐碱地面积已达9.5亿hm2。土壤盐碱化已成为重要的环境问题之一。究其原因主要是不适当灌溉,植被破坏和海水内侵。在人口不断增长,耕地逐渐减少的情况下,改良利用盐碱地具有重要意义。采取的基本方法包括工程措施、耕作措施和综合措施。植树造林是改良盐碱地的生物措施之一,不但可以改善环境,抑制土壤盐碱化,而且可以直接利用盐碱地生产林木果品,提高盐碱地的生产能力和经济效益。
Saline land area has reached 950 million hm^2 on the earth. Thus soil salinization becomes one of the serious environmental issues. The occurrence of salinization are mainly due to unsuited irrigation, plant community damage and seawater intrusion. At present world population is growing, while arable land is decreasing. To cope with the situation amelioration and utilization of salt-affected soil is vital and significant. There are various ways such as engineering measures, farming measures and comprehensive measures to reclaim and exploit this land. Planting trees is an important biological measure to utilize saline soil ,which can not only improve environment ,also increase soil productivity with producing wood and non-wood forest products.
