20世纪最重大的科学成就之一是对地球的新认识:地球不同于任何其它已知星体的特殊性在于它具有一个由宕石圈、水圈、大气圈和生命总体构成的极其复杂的、活跃的表层、这个表层乃是一个靠生命捕获、转化和储存太阳能，靠生命过程驱动物质和能量循环，靠生命活动实现自我调节和控制，并且靠生命和生命法动来保持其远离天体物理学和热力学的平衡的开放系统。生命是这个地球表层系统的中心。人类文明的发展逐步增大对这个系统，的影响。自生命产生以来在漫长的地质历史中形成和发展起来的地球生物圈将不可避免地被人类改造为受人类声制的“理智圈”，从而增大了地球表层系统的不稳定性。从某种意义上说，地球未来的命运取决于人类文明发展的方向。

One of the most important achivements on science in 20th century is the new recognition on the Earth:the Earth，out of the other planets, exhibits very peculiar features because it has an extremely complex and active periphery part (surfacial layers). This periphery part is an open system sustained by inputting solar energe , which is captured , transfered and stored by life. Through the system , cyclings of matters and energe flow are driven and regulated by life activities. This system is self-equilibrated，self-controlled and far away from astrophysical and thermodynamic equilibria mainly because of life and life activities.
Development of human calture influences increasingly on流Earth's periphery system , at last , the natural biosphere that has existed for 3 billion years on the Earth's surface will inavoidably be replaced by so called "noosphere"，which is man一reconstructed，man-controlled and unstable system. Thus the fate of the Earth，to a great extent，will be determined by the direction of human calture evolution.
