摘要

为探究工程弃渣场“苔‒藻”生物结皮对渣土的改良效果，选取高寒地区弃渣场生物结皮修复区，对比分析不同苔藓和藻类配置对渣土理化性质、酶活性和微生物群落的影响.结果表明：（1）生物结皮处理分别提高了土壤铵态氮（最高2.68倍）、硝态氮（最高2.85倍）、有效磷（最高7.67倍）、有机碳（最高达26.11 g/kg）含量.（2）土壤纤维素酶、β-葡萄糖苷酶、植酸酶等酶活性最高分别增加2.00、2.29和45.6倍.（3）此外，微生物多样性与均匀度提升，并引入了互养菌门（Synergistota）、达达菌门（Dadabacteria）等新的微生物门类.“苔‒藻”生物结皮有效提升了土壤养分水平，优化了土壤微生物群落结构.该研究为生物结皮技术在高寒地区生态恢复中的应用提供了理论与实践依据.

Abstract

To evaluate the restorative potential of moss-algal biological soil crusts (biocrusts) on alpine construction spoil

we conducted a comparative field experiment at a spoil-disposal site. We established contrasting moss-algal assemblages and quantified their effects on soil physicochemical properties

enzyme activities

and microbial communities. Biocrust colonization increased soil ammonium nitrogen up to 2.68-fold

nitrate nitrogen up to 2.85-fold

available phosphorus up to 7.67-fold

and soil organic carbon to 26.11 g/kg. Cellulase

β-glucosidase

and phytase activities reached 2.00

2.29

and 45.6 times the control levels

respectively. Additionally

biocrusts enhanced microbial α-diversity and evenness

and enabled the detection of rare phyla such as Synergistota and Dadabacteria. Overall

moss-algal biocrusts improved soil nutrient status and optimized the structure of soil microbial communities. The findings provide theoretical and practical guidance for applying biocrust technology to ecological restoration of alpine spoil sites.
