摘　　要：为探索受损河岸生态修复的理论与技术,以修复4年的河岸生态修复工程为研究对象,从土壤生物学角度评价了人工构建的河岸生境缀块对受损河岸生态系统的修复作用.结果表明,经过4年的恢复,修复区土壤中各种微生物的数量明显高于对照区;修复区土壤动物种类、数量、生物多样性指数以及土壤有机质、N、P、K含量均高于对照区.修复后,受损河岸的土壤性状得到了明显改善,土壤生物多样性及河岸生态系统稳定性得到了提高.人工构建生境缀块的河岸生态修复工程不仅经济成本低,而且具有生态、景观和社会价值,为已建混凝土河岸的生态改造和受损河岸的近自然修复提供了新模式.In order to explore the theory and technique about the restoration of damaged riparian ecosystem, this paper evaluated the remedy effect of artificial spotted habitats that have been built for four years on the damaged riparian ecosystem based on soil biological principles. The results showed that in restored area, the quantities of various soil microbial species were significantly higher, and the species, quantity, and biodiversity of soil animal as well as the contents of soil organic matter, nitrogen, phosphorus, and potassium were all higher than those in un-restored area. After successful restoration, the soil conditions in damaged riparian were significantly improved, which resulted in an increase in soil biodiversity and enhanced the stability of this ecosystem. The remedy technique for the damaged riparian by using artificially spotted habitats not only consumed less cost, but also exhibited great ecological, landscape, and social values, providing a new model for the ecological reconstruction of damaged concrete riparian and the approximately natural remediation of damaged riparian.
