摘要:
随着人类活动的加剧, 环境发生了巨大的变化。从地球生态系统的角度来探讨和研究全球的环境变化, 具有重要的意义。通过对北太平洋海洋生态系统的剖析, 在时间和空间尺度上, 展示了地球生态系统强有力地控制着陆地的沙尘暴、大气的北太平洋季风和海洋的硅来源及输送方式。为了保持向海洋输入大量的Si, 地球生态系统控制着陆地生态系统、大气生态系统和海洋生态系统。研究显示, 地球生态系统使北太平洋的季风与北太平洋边缘的雨季在时间上密切相嵌, 顺利完成近岸洪水和河流的输送与大气的输送之间的相互转换; 同时也使沙尘暴与北太平洋Si 的缺乏在时间上紧密配合, 其强度大小与Si 缺乏的严重程度相一致。因此, 在全球的环境变化下, 海洋Si 的缺乏是在严重加剧。那么, 地球生态系统展示了强有力的控制能力, 维持向海洋水域提供大量的硅, 充分保证海洋生态系统的健康发展。

The control capacity of the earth ecosystem
Abstract:
With the human activities becoming more and more, the environment has been changed a lot. It is very important to study the environmental changes of the earth from the view of earth ecosystem. Herein, the powerful control of land sand storm, the North Pacific Ocean monsoon and the transport way of marine silicon source by the earth ecosystem was shown at the temporal and spatial scale, through thorough analysis of the marine ecosystem in the North Pacific Ocean. The earth ecosystem powerfully controls land ecosystem, atmosphere ecosystem and marine ecosystem in order to keep transporting a large amount of silicon into the sea all the time. The results showed that the earth ecosystem strongly controlled land ecosystem and atmosphere ecosystem, resulting in the fact that in the North Pacific Ocean, the monsoon in the North Pacific Ocean and the rainy season in the fringe of the North Pacific Ocean, in temporal scale, are closely embedded, which helped the successful complete of the alternate switch between the transportation of coastal floods and rivers and the transportation of atmosphere for keeping transporting a large amount of Si into the waters body in the ocean all the time. The earth ecosystem powerfully controlled land and marine ecosystem, resulting in the fact that the stand-storms were closely conjugated with the absence of Si in the temporal scale, and its intensity was consistent with the grave degree of the Si absence. Therefore, under the changes of the global environment, the absence of Si in the sea has been becoming more and more aggravative. Then, the earth ecosystem presented the powerful control capacity, for providing a large amount of silicon into the marine waters and fully ensuring the health development of the marine ecosystem.
