| 摘 要： | 马达加斯加是非洲大陆的离岛。天然森林类型复杂多样。原生性的森林群落主要为常绿林，落叶林以及多刺、肉质的落叶灌木丛。在不同类型的岩石露头发育着岩生矮林；高山上可见山顶矮林，滨海湿地则为红树林。马达加斯加的森林有着独特的植物和动物种类，有着巨大的生物多样性。但由于人类长期对其生境的破坏，不少动物种类已处于濒危状态。到目前为止，60％－85％的森林植被已遭到破坏。非持续的农业轮作是森林植被完整性的主要威胁。在某些地区，火烧林地建立牧场业是引起森林面积减少的主要因素。

| Abstract: | Madagascar is an island off the east coast of Africa. The natural forest of Madagascar is diverse. The original forest is believed to have been predominantly evergreen or deciduous forest or deciduous, spiny, succulent thicket, with rupicolous shrublands occurring locally on various types of rock outcrop, and montane bushland and thicket occurring on the highest mountains or mangroves swamps. Madagascar's dwindling forests are home to an enormous variety of unique plant and animal life but some of them are endangered because of the constant destruction of their habitat by humans. 60%-85% of forest has been destroyed. Unsustainable shifting subsistence cultivation is the major threat. In some areas burning to create cattle pasture is also important. |
