建筑与植物结合的城市生态设计

当前,我国城市绿地率已达相当高的比例,但环境恶化之势仍未得到根本扭转,其主要原因之一,在于城市景观综合生态机能的衰退。将建筑设计与城市植物群落结合,按照植物群落最小面积要求设置大中型绿地斑块、合理限定人为干扰并引导群落演替,就能减少绿地系统的人工维护,完善群落组织,改善城市小气候。而将建筑设计与绿地系统的生态补偿结合,兼顾绿地景观的关键生态过程和重要节点的保育,以绿地系统改善自然采光、通风与景观视觉,则能有效地弥补、修正城市绿地的格局与构成。最后,在建筑设计中结合绿地进行节能设计,利用绿地做功,还能降低建筑全生命周期的运营费用,有利于城市可持续健康发展。

The Urban Ecological Design Based on Integration of Building and Greening

The urban greenspace ratio has been of a very high rate in China,but environmental degradation has not been fundamentally reversed.The reason lies in the decline of integrated ecosystem function of urban landscapes.But with the combination of architectural design and urban greening communities,the establishment of large or medium-sized green patches in accordance with the minimum requirement of greening community scale,and reasonable control of human intervention and greening community evolvement,the artificial maintenance of greenspace can be reduced,the organization of community be improved,and the urban microclimate be ameliorated.At the same time,with the integration of architectural design and ecological compensation of greenspace system,the protection of key ecological processes and key node of greenspaces,the incorporation of greenspace system into architectural design improving natural lighting,ventilation and visual quality,the pattern and composition of urban greenspace can be effectively made up and fixed.Finally,with the combination of architectural design with greenspaces,energy saving design according to different buildings types,and the working of greenspace,the building life-cycle operating costs can be reduced,whilst being beneficial for sustainable urban development.
