为了说明生物多样性,我们先举两个极端例子。生物多样性最丰富的地方,当然数热带雨林,巴西、印尼,还有我国的云南西双版纳、海南三亚,都是生物多样性很丰富的地方,每平方公里的植物、动物种数多在2000种以上。再举生物多样性最贫乏的地方,可能包括沙漠、戈壁,盐碱地,还有我们人工造的纯林。这两种地方,那种好?那个地方更适合人居?答案只有一 To illustrate biodiversity, let’s start with two extreme examples. The most abundant biodiversity, of course, the number of tropical rainforests, Brazil, Indonesia, as well as China’s Xishuangbanna in Yunnan, Hainan Sanya, are rich in biodiversity, places per square kilometer of plants, animals in more than 2,000 species the above. Cite the poorest places where biodiversity is most likely to include deserts, Gobi, saline soils, and the pure forests we make artificially. The two places, the kind of good? That place is more suitable for living in Habitat? The answer is only one
