摘　　要：园林夜景照明助力城市经济发展的同时,干扰植物正常生长规律,影响园林植物健康生长。以上海城市公园中常见的4种园林植物海桐、大叶黄杨、红王子锦带和彩叶杞柳为例,在光照度值150~250 lx的试验环境下,通过不同光质延时4 h照射,分析4种植物的生长指标、叶形态特征、叶绿素含量和生物量的变化,探讨光照度值150~250 lx、环境延时照射对植物生长的影响,以及植物生长指标各参数对不同光质的反应关系。结果表明:4种植物在试验光环境中可正常生长,叶面积形态、总叶绿素含量等指标变化显著;在不同光质照射下不同植物各生长指标的反应不同。因此,光照度值150~250 lx延时4 h照射是适合海桐等4种园林植物正常生长的夜间照明环境,夜景实践中应根据不同植物品种选择不同光质照射以确保植物健康生长。Garden nightscape lighting interferes with the normal growth curve of plants and affects the healthy growth of garden plants though it helps urban economic development.The study puts four common landscape plants in Shanghai urban parks under the test environment with illumination value at 150-250 lx,and analyzes the changes of the 4 species in growth indicators,leaf morphological characteristics,chlorophyll content and biomass by increasing 4 h irradiation with different light qualities.The impact of illumination value at 150-250 lx and prolonged irradiation time on the plant growth is discussed,and the response of the parameters of plant growth index to different light qualities is also studied.The test results show that the four plants could grow normally in the tested light environment,with significant changes in leaf area morphology and total chlorophyll content,and the responses of different indicators of plant growth are different under different light qualities.Therefore,the illumination value at 150-250 lx and 4 h longer irradiation create the nightscape lighting environment suitable for the normal growth of the four landscaping plants.To improve the nightscape,different light qualities should be selected for different plant species to ensure the healthy growth of plants.
