摘　　要：首次提出地球生态系统的C补充机制,并且用框图模型说明了补充机制在运行过程中的每个流程,阐明了无论Si的充足与缺乏,地球生态系统都要将C从大气中移动的海底,储藏起来,完成C的迁移过程。研究结果表明,人类排放CO2引起气温和水温上升,地球生态系统不惜损害陆地生态系统和海洋生态系统,也要启动C补充机制,完成C的迁移,导致气温和水温恢复到动态的平衡。启动C补充机制期间,在输送Si的过程中,地球生态系统给陆地带来三大类型灾害:沙漠化、洪涝和风暴潮;在阻断Si的过程中,地球生态系统给海洋带来一大类型灾害:赤潮。在这些过程中,人类引起大气C的增加与地球生态系统导致大气C的减少充分展现了人类与自然界的相互撞击,这会强烈地产生一系列自然灾害发生,如干旱、沙漠化、沙尘暴、暴雨、洪水、泥石流、山体滑坡、风暴潮和赤潮。人类尽可能减少这些撞击,为地球生态系统的可持续发展,也为人类生存创造良好的环境。The complementary mechanism of carbon in the earth ecosystem was put forward firstly, and each procedure in the complementary mechanism running process is illustrated by the block diagram, which showed that no matter what silicon was enough or lack, and the earth ecosystem would make the carbon in atmosphere into the sea bottom and stored so as to complete the process of carbon transference. It is shown from the study results that CO2 discharged by human caused its rise in air and water temperature, and in spite of the impairment of land ecosystem and marine ecosystem, the earth ecosystem started the complementary mechanism of carbon to complete the carbon transference, resulting in returning the air and water temperature to the normal dynamic balance. During the running process of the complementary mechanism of carbon, in the transportation of silicon, the earth ecosystem brought the three types of catastrophes： desertifieation, flood and storm tide, and in interdicting the transportation of silicon, the earth ecosystem brought the one type of catastrophe, and red tide. In these processes, the increase of carbon in atmosphere caused by human and decrease caused by the earth ecosystem, this fully represented the impact with each other between human and nature. So a series of natural catastrophes intensively occurred, such as drought, desertifieation, sandstorm, storm, flood, mudslide, hill-slide, storm tide and red tide. Human would try to decrease the impact for the sustainable development of the earth ecosystem and the nice environment of human life.
