不良的生物多样性:香港外来物种的入侵调查

Описание к видео 不良的生物多样性:香港外来物种的入侵调查

香港有很多种入侵的外来物种,它们对当地生态环境有什么影响?我们选择几种入侵到当地的生物,分别是巴西龟、凤眼兰、小葵花凤头鹦鹉、罗非鱼、非洲大蜗牛、猕猴、黄牛。经过调查,我们发现,虽然有些生物对当地环境影响甚微,但仍有不少物种对香港的生态系统造成威胁。从外地引入的物种因为没有天敌,本地物种又难以抗衡或制约,从而成为真正的入侵者,打破了生态平衡,改变或破坏了香港的生态环境,严重破坏了生物多样性。
There are many kinds of invasive alien species in Hong Kong. What impact do they have on the local ecological environment? We chose several species that invaded the area, including the Brazilian tortoise, the water hyacinth, the small sunflower cockatoo, the tilapia, the African snail, the macaque, and the ox. After investigation, we found that although some organisms have little impact on the local environment, there are still many species that pose a threat to Hong Kong's ecosystem. Since the species introduced from the field have no natural enemies, the local species are difficult to compete or restrict, thus becoming a real intruder, breaking the ecological balance, changing or destroying the ecological environment of Hong Kong and seriously damaging biodiversity.
