亚马逊平原位于赤道附近,受赤道低气压控制,属于热带雨林气侯,降水丰富,形成高温多雨带,所以形成季节性湿地。
亚马逊森林是一个热带的奇迹,是当今世界上保存最原始最大最好的热带雨林。远离都市的尘嚣和人类工业、商业的文明使得亚马逊热带丛林成为一座返璞归真的孤岛绿洲,它复盖了南美洲700万平方公里(270万平方英里)的土地面积,占去了巴西的大片土地和厄瓜多尔、哥伦比亚、玻利维亚、委内瑞拉、秘鲁和圭亚那的部分领土,被称为"地球之肺"和"绿色心脏"。
The Amazon Plain is located near the equator and is controlled by the equatorial low pressure. It has a tropical rainforest climate and abundant precipitation, forming a high-temperature and rainy belt, so it forms seasonal wetlands.
The Amazon forest is a tropical miracle. It is the most primitive, largest and best preserved tropical rainforest in the world today. Far away from the hustle and bustle of the city and the civilization of human industry and commerce, the Amazon tropical jungle has become an island oasis that returns to nature. It covers 7 million square kilometers (2.7 million square miles) of land in South America, occupying large tracts of land in Brazil and parts of Ecuador, Colombia, Bolivia, Venezuela, Peru and Guyana. It is known as the "lungs of the earth" and the "green heart".
The Amazon River's lower reaches are covered with wetlands, which can be analyzed from the interaction of natural geographical elements such as topography, climate, hydrology, vegetation, and soil.
①Climate: tropical rainforest climate, huge annual precipitation;
②Terrain: low-lying terrain, poor drainage;
③Hydrology: The Amazon River is the world's largest river with a large runoff volume;
④Soil: The brick red soil under the tropical rainforest is heavy and sticky, and surface water is not easy to infiltrate;
⑤Vegetation: lush vegetation, strong water storage capacity.
The reason why the Amazon River's lower reaches are covered with wetlands is that it is located in the equatorial low-pressure zone, with sufficient precipitation.
