| 摘 要： | 湿地具有巨大的环境调节功能和效益,对维持自然界自然生态过程和平衡以及减缓地区、区域的环境变化具有极其重要的作用;同时湿地对区域生态环境变化也具有明显的响应。本文从湿地对洪涝和干旱的缓冲作用、湿地对周边环境的净化作用、湿地充当着CO2的源和汇,湿地植物的生态效应以及湿地对植物对盐分和人类活动干扰的响应等方面论述了松嫩平原盐碱湿地对区域生态环境变化的缓冲作用,指出对生态脆弱带的盐碱湿地进行保护和优化管理是维持区域生态环境安全和区域可持续发展的重要举措。 |

| Abstract: | Wetlands have great environmental functions and benefits,and they play the significant roles in maintaining the ecological processes and balances of nature,reducing the environmental changes at the local and regional level;Meanwhile,wetlands may respond to the regional environmental changes.The buffering of wetlands on flooding and drought,the filtration of wetlands,wetlands acting as source or sink of CO2,the purification of wetland plants and the effects of salt and human activities on wetlands are summarized in this paper,and it is vital for maintaining regional eco-environmental security and sustainable development to conserve and optimally manage the alkaline-salinezed wetlands. |
| Keywords: | Songnen Plain saline-alkalined wetlands eco-environment buffering response |
