引子 一位资深的地质学家曾向我讲述了中生代的故事。 在地质史上,中生代是一个极为特殊的地质年代,它始于2.5亿年前,结束于6500万年前。 在这近2亿年的时期内,地球发生了太多的变化,大陆在分裂、在聚合,陆升、陆沉,长河横流,火山爆发,奠定了今天大陆的基本轮廓。激变促进进化,生物圈缤纷多彩,森林广布。花开四野:鸟在天上飞,鱼在水中游,群兽陆上走。恐龙,这个从古至今最大的动物群落从生到灭完成了它的生存使命,给今天的人们留下了一团团的“谜”。印度洋板块挟风裹雷向欧亚大陆撞来,于是地球隆起了世界第三极——终年披冰盖雪、恢宏冷峻的青藏高原。 在冈底斯山、昆仑山、念青唐古拉山的怀抱里,居住一群含情脉脉的“可可西里”(蒙古语:美丽的少女)——一群高拨6000米以上的雪山群。就是这群少女孕育了长江、黄河,于是滔滔东去江河水哺育了一个伟大的民族——中华民族。
A senior geologist told me about the Mesozoic story. In geological history, the Mesozoic is a very special geologic age, it began 250 million years ago, the end of 65 million years ago. During this nearly 200 million-year period, too many changes have taken place in the continent. The mainland is splitting up and converging. The ups and downs of land, land and sea, and the volcanic eruptions have laid the basic continent of today. Catastrophe to promote evolution, colorful and colorful biosphere, the forest is widely distributed. FOUR wild flowers: the birds fly in the sky, the fish swim in the water, the beast on land. The dinosaur, the largest animal community from ancient times to the present, accomplished its mission of survival from birth to death, leaving a “mystery” to the people of today. The Indian Ocean plate clinging to the wind and bound the Eurasian continent hit, so the earth raised the world’s third pole - year-round ice covered snow, grand and solemn Qinghai-Tibet Plateau. In the arms of the Gangdise, Kunlun Mountains and Nyainqentanglha Mountains, there lived a group of eloquent “Hoh Xil” (Mongolian: a beautiful young girl) - a group of snow-capped mountains at a height of 6,000 meters. It is this group of young girls gave birth to the Yangtze River, the Yellow River, so surging east to the river nurtured a great nation - the Chinese nation.
