摘 要
本文深入探讨了土地整治项目中生态修复技术的关键应用与面临的挑战，并提出了相应的优化策略。随着经济的快速发展和城市化进程的加速，土地资源的过度开发和不合理利用导致了严重的生态问题，生态修复技术成为恢复土地生态系统功能、保障生态安全的重要途径。本文首先概述了土地整治项目的背景，强调了生态修复技术在其中的重要性。随后，文章详细介绍了四种主要的生态修复技术：植物修复技术通过种植特定植物吸收、转化或稳定污染物；微生物修复技术利用微生物的代谢活动降解污染物；物理与化学修复技术则通过物理或化学手段直接去除或改变污染物性质；混合修复技术则是上述技术的综合应用。每种技术都有其独特的优势和适用范围。然而，生态修复技术在应用过程中也面临诸多挑战，如技术评估准确性不足、资金投入有限、社会认知度低以及生态系统复杂多变等。针对这些问题，本文提出了多项优化策略，包括加强跨学科合作，促进技术创新与融合；拓展资金来源，制定支持政策；提高公众环保意识，建立参与机制；实施适应性管理，建立长期监测体系等。综上所述，本文的研究成果对于推动土地整治项目中生态修复技术的科学应用，促进土地生态系统的恢复与可持续发展具有重要意义。

RESEARCH ON ECOLOGICAL RESTORATION TECHNOLOGY AND APPLICATION IN LAND REMEDIATION PROJECTS
ABSTRACT
This paper discusses the key applications and challenges of ecological restoration technology in land remediation projects, and puts forward corresponding optimization strategies. With the rapid development of economy and the acceleration of urbanization process, the overdevelopment and irrational use of land resources have led to serious ecological problems. Ecological restoration technology has become an important way to restore the function of land ecosystem and ensure ecological security. This paper first Outlines the background of land remediation projects and emphasizes the importance of ecological remediation technology in them. Then, four main ecological restoration technologies are introduced in detail: phytoremediation technology absorbs, transforms or stabilizes pollutants by planting specific plants; Microbial remediation technology utilizes the me tabolic activity of microorganisms to degrade pollutants; Physical and chemical remediation techniques directly remove or change the properties of pollutants by physical or chemical means; Hybrid restoration technology is the comprehensive application of the above technologies. Each technology has its own unique advantages and scope of application. However, ecological restoration technology also faces many challenges in the application process, such as insufficient accuracy of technical assessment, limited capital investment, low social awareness, and complex and changeable ecosystems. To solve these problems, this paper puts forward a number of optimization strategies, including strengthening interdisciplinary cooperation, promoting technological innovation and integration; Expand funding sources and formulate supporting policies; Raise public awareness of environmental protection and establish participation mechanism; Implement adaptive management and establish long-term monitoring system. In summary, the research results of this paper are of great significance for promoting the scientific application of ecological restoration technology in land remediation projects and promoting the restoration and sustainable development of land ecosystems.
