摘要:
随着城镇化进程加快和人口急剧增长,人类一系列的生产、生活更加频繁,经济迅猛发展的同时加剧了人居环境空气质量的恶化。空气负离子(NAI)作为综合反映空气质量的重要指标,在改善空气质量方面有显著的效果。在城市环境中,城市绿化是产生空气负离子的主要载体,而绿化植物中竹类植物群落中的空气负离子浓度相较于其他植物明显较高。选择杭州竹文化园中9种园林常见竹类植物群落作为研究对象,测量空气正负离子浓度、群落冠层结构(叶面积指数LAI、冠层覆盖度CC、天空可视度SVF)。采用多元回归分析定量出不同变量因子对于空气负离子浓度及空气质量评价指标变化的相对贡献,探究三者之间的相互关系以及群落冠层结构对于空气负离子与空气质量评价指标的影响。结果表明:夏季时竹类植物群落与对照点相比,日平均空气负离子浓度与空气质量评价指标均达到了极显著差异。群落冠层结构中叶面积指数和冠层盖度越大,天空可视度越小,则群落内的空气负离子浓度和空气质量评价指标越高。空气负离子浓度和空气质量评价指标(CI)与叶面积指数、冠层覆盖度、天空可视度的多元回归方程分别为NAI=375.751-7.709LAI+715.668CC+298.244SVFCI=-0.249+0.29LAI+1.386CC+0.711SVF。未来在设计竹类植物群落时,设计师可以根据多元回归预测模型来预计群落内的空气负离子浓度和空气质量,为园林设计的生态性提供科学依据。
