生态系统在全球变化中的调节作用

讨论在全球变化的背景下,生态系统对全球变化的调节作用.首先论述陆地生态系统对全球变化的调节作用,主要包括陆地生态系统对大气成分的调节以及对全球气候的调节;其次,论述水生生态系统对全球变化的调节作用,主要包括淡水生态系统对全球变化的调节作用以及海洋生态系统对全球变化的调节作用;最后,论述湿地生态系统对全球变化的调节作用,主要包括湿地生态系统对生物多样性保护的功能,湿地对全球变化的元素调节作用以及湿地对气候和水文的调节.

Adjustment Action of Ecosystem in Global Change

Based on the background of global change, the adjustment action of ecosystem for global change is discussed. First, the adjustment action of terrestrial ecosystem for global change is discussed, mostly included the adjustments of terrestrial ecosystem for atmospheric composition and global climate; then, the adjustment action of aquatic ecosystem for global change is discussed, mostly included the adjustments of freshwater and ocean ecosystem for global change; finally, the adjustment action of wetland ecosystem for global change is discussed, mostly included the protective function of wetland ecosystem for biological diversity, the adjustment actions of wetland for elements of global change, climate and hydrologic cycle.
