黑龙江省安达市草地碱化后土壤物理性状变化

调查了安达市盐碱地生物资源环境研究中心试验区羊草Leymus chinensis地土壤物理性状,包括土壤硬度、含水量、饱和导水率、粒径分布、剖面特征和土壤温度等。阐明土地碱化对土壤物理性质的影响,为安达市以及松嫩平原生态环境的修复和土地资源的永续利用提供科学依据。同时,讨论了地下水化学成分和土壤冻融变化对碱化的可能影响,认为在没有植被覆盖的条件下,冻融变化会加剧土壤的碱化程度。

The soil physical properties on Leymus grassland in research site of Anda Alkali Soil Natural Environmental Research Centre was tested in terms of soil hardness,water content,saturated hydraulic conductivity, particle-size distribution,soil profile characteristics and soil temperature. The effects of soil alkalization on soil physical properties was elucidated,which provided scientific basis for ecological rehabilitation of Anda and Sunnen plain,as well as sustainable utilization of land resource.Meanwhile,...
