The invention relates to a saline-alkali soil vegetation recovery structure and recovery method. The saline-alkali soil vegetation recovery structure comprises a plurality of drainage ditches dug in saline-alkali soil, saline-alkali pressing layers arranged on the saline-alkali soil between every two adjacent drainage ditches, saline-alkali soil layers laid on the saline-alkali pressing layers anda plurality of restoration grooves dug in the saline-alkali soil layers. The restoration grooves are filled with a saline-alkali soil improvement substrate used for planting saline-alkali tolerant herbaceous plants, the saline-alkali soil layers are formed by stacking saline-alkali original soil dug out of the drainage ditches on the saline-alkali pressing layers, and the middles of the saline-alkali soil layers are higher than the sides, connected with the drainage ditches, of the saline-alkali soil layers. The saline-alkali soil vegetation recovery structure can effectively reduce the saltcontent in the saline-alkali soil by changing the terrain in combination with the saline-alkali soil pressing layers and filling the soil improvement substrate in the restoration grooves, creates a favorable living space for vegetation growth, realizes vegetation restoration of the saline-alkali soil, and has the advantages of wide application range, convenience in construction, great reduction ofengineering quantity, particularly, large-area saline-alkali soil vegetation is recovered, the cost is greatly saved, and the application prospect is wide.
本发明涉及一种盐碱地植被恢复结构及恢复方法，该结构包括挖设在盐碱地上的多条排水沟、设置在相邻二个排水沟之间的盐碱地上的压盐碱层、铺设在压盐碱层上的盐碱土壤层及挖设在盐碱土壤层上的多个修复槽，修复槽内填充用于种植耐盐碱草本植物的盐碱地改良基质，盐碱土壤层由排水沟内挖出的盐碱原土堆设在压盐碱层上形成，盐碱土壤层的中部高于盐碱土壤层的与排水沟相连的侧部。本发明通过改变地形结合压盐碱层、修复槽内填充土壤改良基质等手段，可以有效降低盐碱土中的含盐量，给植被生长营造有利的生存空间，实现盐碱地的植被恢复，还具有适用范围广，施工便捷，大幅降低工程量，特别是恢复大面积盐碱地植被，大大节约成本，应用前景广阔。
