学者:即使定期检查树木 也不能保证树不倒
(2010-06-26)​
<!-- /ssi/slice/imugroup01.shtml --><STYLE type=text/css>fieldset { width: 306px; border: 1px solid #990000; }legend { font-family: Arial,"宋体"; font-size: 12px; font-weight: bold; color: #990000;}</STYLE>  国大生物科学系副教授陈长华受访时说,虽然有其他因素可以影响一棵树的稳定性,但强烈的雨势与风势在很大程度上能影响树的坚实度,昨天有多棵树倒下主要是狂风暴雨所致。

  他说,大量的雨水会导致泥土松软,强烈的风势则让树木承受不少“压力”,可对树根造成损伤,尤其是在斜坡上的树木,“扎根力”要更强。
  陈长华说,恶劣的天气会导致树倒,这是一个“得接受的事实”。这也是为什么经常被台风袭击的香港较少在路旁栽种高大树木。新加坡当局能做的就是定期检查树木的健康,但即使如此,也不能保证树倒事件不会发生。
  例如出现车祸时,路旁的树木被车辆撞到,会“受伤”而影响树的健康,因为树木一旦因意外“破皮”,会让病菌侵入,导致树木生病。树木生病,没得到照顾就会影响它的稳定与坚实度。   至于树木品种,属于沿海品种(coastal species) 的树木对风势比较有“抵抗力”,这些树木就包括黄盾柱木 (Yellow Flame)、海苹果树。以往本地还有在路旁栽种海苹果树,但由于掉落的海苹果果实可损坏车辆,现在已不栽种在路旁。目前路旁树木以雨树、青龙木与桃花心木(Mahogany)居多。虽然雨树属于陆地品种(inland species) ,却是相当坚硬的树木。
