人面竹等10种观赏竹冬季滞尘效应与规律研究

为了对福州市江滨大道的10种观赏竹冬季的滞尘效应进行监测分析，应用直接采样和统计分析的方法对其单位叶面积滞尘量在时间、高度和方向3个方面的变化进行研究。结果表明，滞尘量较高的观赏竹种为唐竹、银丝大眼竹、泰竹、人面竹、绿槽毛竹和早园竹；其中，鼓节竹和青丝黄竹滞尘量在雨后第4天呈现上升趋势，人面竹、绿槽毛竹、黄金间碧竹和银丝大眼竹滞尘量呈现下降趋势，这与竹种叶片大小、分枝形态和栽植形式相符；人面竹、唐竹、绿槽毛竹、黄金间碧竹、早园竹、银丝大眼竹和鼓节竹在距离地面150 cm处单位叶面积滞尘量高于200 cm处，尤以绿槽毛竹、银丝大眼竹和鼓节竹差异显著，斑竹、泰竹、青丝黄竹则相反，但差异不显著，而在同一高度，唐竹滞尘能力最强，黄金间碧竹滞尘能力最差；各个竹种不同方向滞尘量存在差异，这与竹种栽植位置和车辆行驶方向有关。

Study on Dustfall Adsorbing Capacity of 10 Bamboos Including Phyllostachys aurea etc.in Winter and Its Laws

In order to research the dustfall adsorbing capacity in winter and its laws of 10 species of ornamental bamboo in Fuzhou were chosen to systematically study the dust accumulation on the leaves of different plants in time, height and direction three aspects by direct sampling and measurement, and statistical analysis as well. The results showed that： the dustfall adsorbing capacity of Sinobambusa tootsik, Bambusa eutuldoides var. basistriata, Thyrsostachys siamensis, Phyllostachys aurea, Phyllostachys heterocycla ＇ Viridisulcata ＇ , Phyllostachys propinqua; Bambusa tuldoides ＇ Swolleninternode ＇ were higher than others, and Bambusa eutuldoides var. viridi-vittata showed a rising trend after the rain in the fourth day, Phyllostachys aurea, Phyllostachys heterocycla ＇ Viridisulcata ＇ , Bambusa vulgaris ＇ Vittata ＇ , and Bambusa eutuldoides var. basistriata have declined; Phyllostachys aurea, Sinobambusa tootsik, Phyllostachys heterocycla ＇ Viridisulcata ＇ , Bambusa vulgaris ＇ Vittata ＇ , Phyllostachys propinqua, Bambusa eutuldoides var. basistriata, Bambusa tuldoides ＇ Swolleninternode ＇ , in the distance the ground 150 cm unit leaf area dustfall adsorbing capacity more than 200 cm, especially Phyllostachys heterocycla ＇ Viridisulcata ＇ , Bambusa eutuldoides var. basistriata, Bambusa tuldoides ＇ Swolleninternode ＇ had the significant differences, other was opposite, but the difference was not significant, and in the same height. The dustfall adsorbing capacity of Sinobambusa tootsik was the strongest, Bambusa vulgaris ＇ Vittata ＇ was the worst. The dustfall adsorbing capacity was different in different directions in ten ornamental bamboos.
