    Abstract:

    [Objective] We studied the effects of vegetation restoration on soil physicochemical properties, enzyme activities, and fungal community of reconstructed soil in mining area of the Loess Plateau, to evaluate the effects of vegetation restoration on soil ecological restoration.[Methods] In Jungar Banner of Inner Mongolia Autonomous Region, three typical types of vegetation restoration (shrubs, arbors, and herbs) and unreclaimed land for sampling (0-20 cm) were chosen. The diversity and community of the soil fungi were analyzed using a high throughput, and the important factors affecting the community diversity of the fungi under different vegetation restoration managements were discussed in combination with the physicochemical properties of soil.[Results] ① Compared with unreclaimed land, the three typical vegetation restoration types, not only improved the soil physicochemical properties and enzyme activities significantly, but also improved the soil fungal operational taxonomic units (OUTs) and diversity index with significant differences, among which shrubs had the best effect. ② The relative abundance of the main phyla of fungi had a trend as follows:Ascomycota > Basidiomycota > Glomeromycota, and the sum of those phyla was more than 50% of the community. The community structure of the soil fungi remained stable among the four sampling sites. ③ The soil water content was the main factor affecting the structure of the fungal community.[Conclusion] Vegetation restoration affects the soil physicochemical properties, enzyme activities, and fungal community diversity. Ecological restoration in mining area of the Loess Plateau is a long process, in which shrubs should be planted to improve the ecological environment of the reconstructed soil.
