摘    要:硅是植物生长发育的有益元素,其在生态系统内的迁移转化是维持生态系统结构与功能的决定性因素之一。近年来,陆地生态系统硅循环特别森林生态系统硅循环在全球生物地球化学循环中的重要性,受到越来越多的关注。该文总结了国内外森林生态系统硅循环研究的成果,在综述了硅在森林生态系统中的存在形态、分布、循环过程的基础上,总结了森林生态系统硅循环的特点、作用及其影响因素,并指出典型森林生态系统类型中硅循环规律的研究、森林生态系统与其它生态系统硅循环的比较研究、森林生态系统硅循环对全球气候变化的影响和响应研究和人类干扰对森林生态系统硅循环的影响的研究将是今后开展森林生态系统硅循环研究的重点。

关 键 词:森林生态系统  硅循环  进展

Abstract:Silicon biogeochemistry plays an important role in controlling structure and function of forest ecosystems. Forest vegetation does recycle substantial amounts of silicon from and back to the soil solution with phytoliths as an intermediate phase. However, silicon as a beneficial inorganic element in forest ecosystems has not been systematically studied. In recent years, the importance of silicon biogeochemistry in terrestrial ecosystems, especially in forest ecosystem, has received increasingly more attention. Advances of silicon cycling in forest ecosystem were reviewed in this paper introducing silicon chemical forms of silicon and distribution, and the silicon biological cycling including characteristics, significance and influencing factors in forest ecosystems. Specific questions that should be addressed in future research may be included, but not limited to: (1) The mechanism of silicon cycling in typical forest ecosystems; (2) The difference of silicon cycling between forest ecosystems and other ecosystems; (3) The influence of silicon cycling in forest ecosystem on global climate change and the response of silicon cycling in forest ecosystem to the global climate change; and (4) The effect of human interference on silicon cycling in forest ecosystem.
Keywords:forest ecosystem  silicon cycling  review
