环境因子对挺水植物固碳能力的影响进展

摘要/Abstract

摘要： 挺水植物具有较强的固碳能力和碳汇潜力，在提高淡水生态系统固碳能力方面发挥了重要作用。本文总结了挺水植物光合固碳机理，并从气候气象因子、水文动力因子和水体理化因子3个方面分析主要环境因子对挺水植物固碳能力的影响。挺水植物固碳能力的直接影响因子包括光照、温度、氨磷营养盐、水体盐度和水体重金属，这些因子能够通过影响叶绿体及光合作用过程中的所需酶、叶绿素浓度等直接作用于挺水植物光合作用；间接影响因子则通过影响挺水植物生长发育及植株结构间接影响挺水植物固碳能力，包括水位、水流，流速和降水。研究提出加强水体理化指标监测，合理调控水位高度，降低污染负荷及外界干扰，以确保生态系统的稳定性、挺水植物生长发育及固碳能力，并因地制宜制定植物配置方案，发挥不同植物的协同性，为提高挺水植物碳汇能力提供参考。
