摘要:
 为解决滨海盐碱地生态环境脆弱、已有生态修复措施耗费大、植被成活率低问题,通过原土改良、乡土耐盐碱植物不同形式的栽植、养护,分析和评价不同改良方法对滨海盐碱地的生态修复效果。结果表明,通过场地平整、深耕晒垡、增施有机肥、中耕通气、浅耕均匀等改良措施,能够使0~60 cm土壤的理化性状明显改善,土壤全盐平均降低0.088%;在原土改良基础上栽植植被,相同养护模式下柽柳栽植区全盐平均降低0.33%,翅碱蓬栽植区全盐平均降低0.204%,柽柳与翅碱蓬混合栽植区全盐平均降低0.36%;单一栽植柽柳,在不同养护方式下,未养护区全盐平均升高0.031%,未起到改良效果,常规养护区全盐平均降低0.33%,优化养护区全盐平均降低0.47%。由此可见,土壤结构的改良、植被的选择、种植层次设置、管理养护等措施对滨海盐碱地原土生态修复效果明显,可以在当地推广应用。
Abstract:
 In order to solve the problems existed in coastal saline-alkali lands,such as vulnerable ecological environments,high cost of eco-restoration by conventional methods,and low survival rate of planting vegetation,several methods for eco-restoration were compared and evaluated,such as improving the original soil,cultivating and tendering native saline-alkali tolerant plants.The results showed that the indices of saline-alkali soil in the depth between 0-60 cm were significantly improved and the total salt content decreased by 0.088% by the application of the integrated methods,such as land leveling,deep ploughing,organic fertilizer adding,upturned soil sunning,intertillage ventilation and shallow plough.After planting different plant species in the improved soil with the same maintenance methods,it was found that the total salt contents decreased by 0.33%,0.204%,and 0.36%,respectively by planting Tamarix chinensis,Suaeda heteroptera,and two species mixed.In T.chinensis planting area,the total salt content in non-maintenance area increased by 0.031%,however,in routine and optimized maintenance area,the total salt content decreased by 0.33% and 0.47%,respectively.These results showed that the soil improvement,plants selection,planting levels and maintenance methods had useful effects on the original soil eco-restoration in coastal saline-alkali land,which could be proposed for local application.
