摘要
相较自然郊野环境,城市同样是多种生物的重要栖息地。城市生物多样性保育对维持城市生态系统平衡、保障人居环境和提升市民幸福感意义重大。在我国快速城市化进程中,面临高强度开发建设需求压力,“城市生境体系”规划设计需要重点关注三大要点:首先是自然荒野保育,即指认和保护好城市中高价值的原生或次生“城市荒野”;其次为蓝绿廊道链接,即通过蓝绿网络体系规划为城市区域的生物栖息与自由迁徙预留足够的空间;最后为生境修复与营造,即通过生态设计手法提升城市蓝绿体系的自然度与生境质量,营造高质量“近自然生境”。
Compared to rural areas,urban environment is also a critical habitat type for diversified wildlife species.The conservation of the urban biodiversity is significantly important for the balance of the urban eco-system,the improvement of living environment for the citizens,and also the happiness of the citizens.Three key issues should be emphasized for the planning and design of the“urban habitat”due to the pressure brought by the rapid urbanization process in China.The first issue is the mapping and conservation of the“urban wilderness”which should be considered high eco-value.The second issue is the urban blue and green corridor network which allows the free migration of the urban wildlife.The third issue is the scientific restoration and creation of the new semi-nature“urban habitat”which can support diversified wildlife.The article discusses the planning and design approaches of the three issues through recent AECOM projects.
