广州高校图书馆外环境的比较分析及基于群落优化的改造策略

Comparative Analysis of the External Environment for University Library in Guangzhou and Optimization Strategies Based on Plant Community Structure

本文通过对广州9所高校所属12所图书馆进行调查发现，外环境设计在人流和物流组织方面基本满足需要，但在室外阅读和休息、静噪及调节小气候方面的功能较弱。针对各图书馆存在的这些问题，本文进一步提出了基于植物群落优化的改造方案：对主要的噪声源，构建枝叶垂直密度大的复层植物群落以静噪；选择具有适当透光率的乔木树种，营建阅读区；在人行区域以遮荫降温为主要目标构建复层植物群落，增强人体的舒适度；在休息区适当配置一些色彩丰富、形态和质感各异、香气宜人的植物，提供视觉、嗅觉、触觉等全感冒休息空间。

Through the investigation of 12 libraries in 9 colleges and universities in Guangzhou, this paper found that the external environment design basically met the needs of human flow- and logistics organization, but the function was weak in outdoor reading and rest, quieting and adjusting the mieroelimate. In view- of the existing problems in li- braries, this paper proposed a reform scheme based on the optimization of plant communities. For the main noise source, the complex plant community with large vertical density of the branches and leaves was constructed, and the tree species with appropriate light transmittance were selected and the reading area was built. In the human area, the complex plant community was constructed with shading and cooling as the main goal, and the comfort degree of the human body was enhanced; some colorful and forms were properly arranged in the rest area. Plants with different tex- ture and pleasant fragrance provided a full sensory rest space for sight, smell and touch.
