| 中文摘要: |
| 以郑东新区24条道路行道树为研究对象,采取实地调查与抽样调查相结合的方法,对郑东新区行道树组成特征、树干日灼情况及其影响因素进行分析,为管护技术措施制定提供科学依据。结果表明,研究区内1 600株行道树中含14科24属28种,落叶树种占比76.19%;优势树种为法桐,且相对多度为19.63%,聚集程度过高不利于生态结构稳定和可持续发展;依据日灼伤害率和病情指数特征,严重受害的道路为春华街,树种为七叶树、枫杨;卡方检验表明道路走向、遮荫情况、下垫面性质、绿带类型、树干管理、修剪方法对树干日灼均存在显著影响(P<0.05)。 郑东新区内常绿落叶比例失衡,法桐应用频率过高,部分道路和树种树干日灼伤害严重,建议增加常绿和抗日灼树种应用,并从规划、栽植及科学管养等方面综合防治日灼伤害。 |

| This study investigated street trees along 24 roads in Zhengdong New District, analyzing the composition, sunscald damage, and influencing factors of street trees through field and sampling surveys. The results showed that among 1 600 trees surveyed, there were 28 species from 24 genera and 14 families, with deciduous species accounting for 76.19%. The dominant species, Platanus orientalis, had a relative abundance of 19.63%, but excessive aggregation threatened ecological stability and sustainable development. Severe sunscald damage was observed on Chunhua Street, primarily on Aesculus chinensis and Pterocarya stenoptera species. Chi-square tests indicated significant effects (P<0.05) of road orientation, shade, ground surface type, greenbelt design, trunk management, and pruning methods on sunscald. The study highlights an imbalance in evergreen-deciduous ratios, overuse of P.orientalis, and severe sunscald in certain areas. Recommendations include diversifying species with evergreens and sunscald-resistant trees, along with integrated planning, planting, and maintenance strategies to mitigate damage. |
