干旱与半干旱地区的生态恢复与景观重塑研究

Research on Ecological Restoration and Landscape Design in Arid and Semi-Arid Areas

在城市化进程中,干旱与半干旱地区脆弱的生态系统易遭到破坏。单一学科指导生态恢复项目的实践具有局限性,应发挥风景园林学科优势,使生态恢复与景观重塑相结合。本文选择瓦迪哈尼法河谷与塔梅拉保水景观两个经典景观案例,重点分析适应干旱与半干旱地区的气候条件的景观设计方法,进而从规划设计尺度、生态服务功能、地域景观特色、传统营建智慧四个方面总结相关经验,以期为中国干旱与半干旱地区生态恢复、景观规划设计实践和相关项目决策提供参考和建议。

In the process of urbanization,the fragile ecosystem in arid and semi-arid areas is always destroyed easily.The practice of ecological restoration projects guided by a single discipline is limited.So the advantages of landscape architecture should be utilized and ecological restoration and landscape design should be combined.The paper selects two classical landscape cases of Wadi Hanifah Valley and Tamera Water Landscape,analyzes the landscape design methods under the climate conditions in the arid and semi-arid regions,and summarizes relevant experience from four aspects of planning and design scale,ecological service functions,regional landscape characteristics and traditional construction wisdom,with a view to providing some reference and suggestions for the ecological restoration,landscape planning and design practice and relevant project decision-making in the arid and semi-arid areas in China.
