道路乔木落果安全重量值研究

A Research of Safety Weight Data of Road Tree Fruits

道路乔木美化城市,改善生态,贴近市民的日常生活。观果乔木是城市亮丽的风景线,然而部分乔木落果却对行人及行车造成了安全隐患。研究华南地区乔木落果安全重量数值。通过收集人体医学受创数值和汽车耐撞击指标,经过物理力学公式演算,获得对人车通行无威胁的落果重量安全范围,为各类道路绿地设计选用及培育改良观赏性乔木提供参考。有针对地设计各重量级别的落果乔木种植位置;改良乔木品种,使果实瘦小化;用药物抑制结实;用水压车喷射花蕾减少结实,是消除落果乔木隐患的有效措施。

Road trees beautify the city, improve the ecology, draw near citizens＇ daily life. Trees of ornamental fruit are the beautiful scenery line of the city, but however, they also cause safety hazards to passers-by and cars. This article researched the problem of fruit weight, collecting the index of human medicine and car impact-resistance, and through calculation by physical mechanics formula, got the safety weight data for people and cars. The safety data will provide reference for the design of greenbelt and the planting of ornamental fruit trees. There are many ways to remove the hidden dangers of fruits, such as using different fruit trees for different roads, improving tree varieties to make the fruit smaller, using pharmaceuticals to restrain fructification, and erupting water from hydraulic cars to make flower buds lesser.
