盐碱地是一种重要的土地资源,随着人口压力不断增大,人们越来越重视开发利用大片分布的盐碱荒地来缓解危机。土壤盐渍化已上升为全球问题,并受到国际学术界的特别关注。由于土壤里面所含的盐分对作物的正常生长产生影响,对当地土地利用有很大的影响。我国碱土和碱化土壤的形成,大部分与土壤中碳酸盐的累计有关,因而碱化度普遍较高,严重的盐碱土壤地区植物几乎不能生存。本文就河北省为例,对盐碱地进行科学、客观的阐述。
Saline-alkali land is an important land resource. With population pressure increasing, people pay more and more attention to developing and utilizing large-scale saline-alkali wasteland to alleviate the crisis. Soil salinization has risen to a global problem and has received special attention from international academia. Since the salt contained in the soil has an effect on the normal crop growth, it has a great impact on the local land use. The formation of alkaline earth and alkalized soil in our country is mostly related to the accumulation of carbonate in the soil. As a result, the alkalization degree is generally high, and the plants in severe saline-alkali soil can hardly survive. In this paper, Hebei Province as an example, a scientific and objective description of saline-alkali land.
