或许你认为热带雨林并没有太大的挑战性,气候温暖、空气湿润,无数的野生动物以此为家,似乎一片其乐融融的样子。然而,穿越一片雨林,可能远比你想象的要困难很多。征服热带雨林,首先要面对的是极端的降水状况。热带雨林中的年降水量普遍在1750毫米到2000毫米以上,赤道附近的典型热带雨林降水量甚至可以达到8000毫米以上,是北京年均降水量的12倍。如此巨大的降水也造就了世界上最宏伟的河流。径流量占世 Perhaps you think the tropical rain forest is not too challenging, warm climate, humid air, countless wildlife as a home, it seems a happy and enjoyable look. However, crossing a rainforest may be far more difficult than you think. To conquer the rainforest, we must first face the extreme precipitation situation.

The precipitation in typical tropical rainforests near the equator can even reach over 8,000 mm, which is 12 times the annual average rainfall in Beijing. Such a huge precipitation also created the world’s most magnificent rivers. Runoff accounts for the world
