亚热带常绿阔叶林是一种重要的植被类型，主要分布在东亚地区，优势类群主要是壳斗科、樟科、木兰科和山茶科。我国亚热带常绿阔叶林分布在北纬24°至32°、东经99°到123°的范围内，具有丰富的生物多样性。生物多样性是人类赖以生存的物质基础，在当今全球气候变化背景下，东亚亚热带常绿阔叶林将会如何演化是一个重要的科学问题。尽管预测亚热带常绿阔叶林在未来的变化趋势还十分困难，但是通过研究它过去的演化历史可为...

最早 霸王龙化石 辽宁
2009/9/14
世界上迄今为止最早的霸王龙化石日前在辽宁省朝阳市境内出土。科学家们在初步研究后认为，这种个体庞大的霸王龙生存于1.2亿年前的早白垩纪，比北美、蒙古等地已经发现的同类霸王龙要早5000多万年。这次在热河古生物化石中首次发现霸王龙化石，对研究霸王龙的起源、迁徙和进化具有重要科学价值。
