生态修复背景下园林园艺类博览会 植物景观营建研究

在生态文明建设的大背景下，生态修复已经成为中国园林园艺类博览会的热点亮点，这对植物景观营建提出了新的要求和挑战。通过回顾我国综合性园林园艺类博览会在生态修复方面的探索，结合科学绿化的建设要求，提出生态修复背景下园林园艺类博览会中植物景观营建的目标需要综合生态、城市景观、城市事件的三重要求，遵循问题与目标导向相结合、人工修复和自然恢复相结合、景观塑造和群落营造相结合的工作要点。综合国内外相关植物景观营建实践，探讨在全园规划尺度、展园设计尺度和展后利用方面如何将生态修复和植物景观营建实践相结合，为今后园林园艺类博览会以及更大范围的风景园林生态修复实践提供参考。

Planting Design of Expo Park under the Background of Ecological Restoration

Under the background of ecological civilization construction, ecological restoration has become a hot point of garden and horticulture expos in China in recent years, which raises new requirements and challenges to plant design. The study reviewed the ecological restoration program in the expo parks of China and found the discrepancy between these projects and national guidelines on scientific greening. Planting design and construction is recommended to integrate the requirements of ecology, urban landscape and urban events, develop strategies based on site issues, reasonably arrange artificial repair techniques and natural recovery processes, and create biocoenosis and beautiful landscape at the same time. This paper also discussed the strategies under different situations through case studies, including planning of the whole park, design at the micro scale and long-term sustainability in order to provide refferences for design processes and practices in the future.
