Alpine sand dunes restoration is extremely difficult but important in the ecosystem restoration. Sand dunes are known as harsh soil and poor seed bank which freed from advantages on plants growth naturally. Effective restoration measures are required to guide the sand dune restoration. Here, indigenous grass (Elymus nutans) was sown in sand dune on the Zoige Plateau and treated with no sand barrier (CK) and environmental friendly materials including wicker sand barrier (wicker) and sandbag sand barrier (sandbag). The soil conditions were assessed by measuring the soil moisture and nutrients of the topsoil, and interspecific relationship and population niche were utilized to analyze the plant community structure variances among different restoration measures. Results showed that the soil and vegetation in the sand barriers measures were better than that in the CK. The soil moisture in the sandbag measure was 16.67% higher than that in the wicker measure. The nutrients content and microbial biomass were also the best in the sandbag measures. The ratio of strong association was the highest in the sandbag measure and the lowest in the CK, whereas the plants had the highest none association ratio in the CK. In addition, the average population niche overlap ranked by sandbag (0.39)>wicker (0.32)>CK (0.26). Thus, incorporation of sand barriers and indigenous grass seeding in alpine sand dunes could promote the sand dune restoration. And the sandbag measure showed a stronger improvement effect on the sand dune soil and vegetation conditions than the wicker measure.

“…Moreover, soil amendments may also provide indispensable assistance during the sand dunes restoration. Except for soil nutrients regulation, bioactive fertilizer amendment may also be an effective and environmentally friendly measure to promote the microbial biomass and accelerate restoration in alpine areas [43, 44].…”

2Restoration of alpine sand dunes has been increasingly attracting the attention of ecologists due to their 3 difficulty and importance among the mountain-river-forest-farmland-lake-grass system (referred as 4 meta-ecosystem) restoration. Alpine sand dunes are suffered from unstable soil and lack of plants. 5Efficient restoration measures are vital to guide the sand dune restoration. Whether the engineering 6 materials co-applied with seeding could achieve considerable restoration in such areas? Here, sandbag 7 and wicker as environmental friendly materials combined with Elymus nutans seeding were 8 implemented on the Zoige Plateau sand dune, comparing with the 'control' treatment that only seeding. 9We assessed the topsoil conditions by sampled the surface soil and measured the water capacity and 10 nutrients. We also utilized interspecific relationship and population niche to analyse the plant 11 community structure variances among different restoration measures. Results showed that the soil 12 conditions got clearly improved in sandbag area than that in wicker area when compared with that in 13 control area. The community in control area was the least structured, while the species showed the 14 closest related in sandbag area. In addition, average population niche overlap showed a control (0.26) 15 ﹤wicker (0.32)﹤sandbag (0.39) ranking. Thus, we suggested that sandbag or wicker co-applied with 16 indigenous grass seeding is a practical and quick restoration approach in alpine sand dunes, and the 17 sandbag may surpasses the wicker. Moreover, soil amending measures including nutrient improvement, 18and microbial fertilizer addition may further accelerate sand dune restoration. 19 Keywords: interspecific relationship; niche; Elymus nutans; sand barrier; restoration 3 20 Introduction 21The terrestrial ecosystem has experienced increasingly severe land degradation and desertification 22[1]. Desertification threatens the ecological safety and its restoration is one of the vital elements in the 23 mountain-river-forest-farmland-lake-grass system (referred as meta-ecosystem) restoration [2, 3]. The 24 long-termed complex causes (e.g., overgrazing, climate change) accelerate desertification process and 25 the sand dunes are expanding continuously on the Zoige Plateau [4-6]. Sand dunes are generally 26 covered by nutrient devoid sandy soil that lacks favourable properties for plant growth and is prone to 27 wind erosion [7]. The expanded sand dunes destroy fertile land and welfare of local populations. For 28 example, they threaten livestock productivity, society development, ecological civilization, household 29 income or human beings health [8-10]. Hence, sand dunes restoration is crucial in ensuring the 30 conservation and sustainable development of the Zoige Plateau and meeting aspiration for better living 31 standards in local people. 32Decades worth of works have been conducted on sand dunes restoration [11, 12]. Mechanical sand 33 barriers as the classical and simplest measure have been shown to contribute to re...

Karst rocky desertification (KRD) is a type of land deterioration, resulting in the degraded soil and a delicate ecosystem. Previous studies focused on the influence of KRD on the animals and plants, the impact of KRD on microorganisms, especially soil fungi remains to be discovered. This study reveals the change in the soil fungal community in response to KRD progression in southwest China. Illumina HiSeq was used to survey the soil fungal community. Results showed that the soil fungal community in the severe KRD (SKRD) was noticeably different from that in other KRD areas. Statistical analyses suggested that soil TN was the primary factor associated with the fungal community, followed by pH. Phylum Ascomycota was significantly abundant in non-degraded soils; whereas Basidiomycota predominated in SKRD. The ratio of Ascomycota/Basidiomycota significantly decreased along with KRD progression, which might be used as an indicator of KRD severity. Phylum Basidiomycota was sensitive to changes in all the soil properties but AP. Genus Sebacina might have the potential to promote vegetation and land restoration in KRD areas. This study fills a gap of knowledge on changes in soil fungal communities in accordance with KRD progression.
