Jake Misbauer: 树木高度差异的主要原因在于树种的不同。不同树种就像猫科动物中的家猫和狮子一样,存在着巨大的体型差异。红杉等树种在理想的生长环境下可以长得非常高大,而生长在恶劣环境下的树木,例如北极地区的矮桦树,由于生长周期短和环境条件恶劣,其高度就会受到限制。 此外,生长环境也对树木高度有显著影响。充足的水分、合适的温度和土壤中的养分等因素都会影响树木的生长。在气候温和、水分充足、土壤肥沃的地区,树木往往能够长得更高更大;而在气候恶劣、资源匮乏的地区,树木的生长就会受到限制,最终高度也会相对较低。 总而言之,树木高度的差异是树种和生长环境共同作用的结果。不同树种具有不同的遗传特性,决定了其生长潜力;而不同的生长环境则会影响树木的生长速度和最终高度。

There are all different kinds of trees in the world, from towering redwoods to tiny willow trees smaller than an action figure. Why are there so many different sizes of trees, anyway? We asked tree expert Jake Miesbauer to help us find the answer.
