摘要:

在国家政策高度重视生态自然修复的背景下,系统梳理了生态自然修复理念、效果及应用条件,探讨了人工促进生态植被自然修复的概念、范围及技术方法,展望了未来进一步研究的重点方向,以期推动自然修复模式的发展进步及其在国家生态建设领域的有效应用。通过生态自然修复、人工促进自然修复与人工恢复等技术模式技术要点的对比,认为人工促进自然修复模式需采取有限的人工治理措施实现植物自然恢复的效率与质量提升,常规生态修复技术方法均可认作人工促进生态修复措施,但需界定人工干预程度。其中,需基于生态承载力理念,考虑界定人为措施治理面积占比与当地自然植被盖度之间的比例关系。研究认为人工促进自然修复模式下,需要构建植被种源区与扩繁区两大体系。其中,种源区可通过植被种植区域选择、适生植物选择与植被建植处理过程,为未处理区域的植被自然恢复提供长期的种源条件;扩繁区可通过地表微地形整理提升粗糙度,来促进区域内的天然落种的截留与植物萌发生长。预期关键节点的植被建植、土壤改良、微地形塑造研究,典型脆弱生态或不利环境条件下的针对性技术研究以及技术规范、考核指标编制等,将成为未来人工促进自然修复的重要研究方向。

Abstract:

In order to promote the technology development and progress of the ecological natural restoration and its effective application in the field of national ecological construction, the concept, effects and application conditions of ecological natural restoration are systematically sorted out, and the concept, scope and technical methods of artificial promotion of ecological natural restoration are discussed, and the key directions for further research are prospected, given that the national policy attaches great importance to ecological natural restoration. Through the comparisons of technical points of ecological natural restoration, artificial promotion of natural restoration and artificial restoration, it is suggested that the artificial promotion of natural restoration mode need to take limited artificial treatment measures to improve the efficiency and quality of natural plant restoration. Conventional ecological restoration methods can be regarded as artificially promoted ecological restoration measures, while the degree of manual intervention needs to be defined. The ratio between the proportion of the area under artificial measures and the coverage ratio of the local natural vegetation of the artificial promotion of natural restoration mode should be considered based on the concept of ecological carrying capacity. Therefore, it is necessary to construct two systems of vegetation provenance area and propagation area under the artificially promoted natural restoration mode. The provenance area could provide long-term provenance conditions for the natural restoration of vegetation in the untreated area through the process of vegetation planting area selection, adaptive plant selection and vegetation construction. The roughness of the planting propagation area would be improved through surface micro-topography shaping to promote the interception of natural seeding, plant germination and plant growth. At last, it is expected that research on vegetation establishment, soil improvement, and micro-topography shaping at key nodes, targeted technical research under typical fragile ecological areas or adverse environmental conditions, as well as technical specifications and assessment indicators, will become important research directions for artificial promotion of natural restoration in the future.

Key words: ecological restoration, natural restoration, vegetation restoration, artificial promotion, provenance zone, micro- topography
