劇情簡(jiǎn)介

  【內(nèi)容簡(jiǎn)介】  東非大裂谷自紅海至贊比西河口,連綿三千里,從太空都能看到。這里是多姿多彩的地方,有噴發(fā)的火山、覆蓋著森林的高山、美麗的峽谷、廣袤的草原、巨大的平湖和河流,是鱷魚、河馬、獅子、大象、火烈鳥和非洲人的家園。BBC采用最新的高清攝影技術(shù),探討了形式東非大裂谷的地質(zhì)力量,展現(xiàn)世界上野生動(dòng)物品種最多的地貌?! isible from space, Africa&#39;s Great Rift Valley runs three thousand miles from the Red Sea to the mouth of the Zambezi. It&#39;s a diverse terrain of erupting volcanoes, forest-clad mountains, spectacular valleys, rolling grasslands, huge lakes and mighty rivers, and is home to crocodiles, hippos, lions, elephants, flocks of flamingos and a diversity of indigenous peoples.  Using state-of-the-art high definition filming techniques, this series investigates the geological forces which shaped East Africa&#39;s Great Rift, and which make it one of the world&#39;s most wildlife-rich landscapes.  Part 1: Fire  The valley is the product of deep-seated geological forces which have spewed out a line of cloud-wreathed volcanoes stretching from Ethiopia to Tanzania. Their peaks provide a refuge for East Africa&#39;s most extraordinary wildlife, including newly discovered and previously unfilmed species which have evolved surprising survival strategies to cope with their challenging mountain environment.  Part 2: Water  The Great Rift Valley channels a huge diversity of waterways - rivers, lakes, waterfalls, caustic springs and coral seas - spanning from Egypt to Mozambique. Some lake and ocean deeps harbour previously unseen life-forms, while caustic waters challenge life to the extreme. But where volcanic minerals enrich the Great Rift&#39;s waterways, they provide the most spectacular concentrations of birds, mammals and fish in all Africa.  Part 3: Grass  The Great Rift Valley provides the stage for an epic battle between trees and grass - its course influenced by volcanic eruptions, landscape and rainfall. On its outcome rests the fate of Africa&#39;s great game herds. In the Rift&#39;s savannas, grazers and their predators struggle to outwit each other, forcing one group of primates to develop a social system that paved the way for the evolution of mankind.
