我国湿地变化的气候效应研究综述

Review on Research Progress of Impact on Climate of Wetland Change in China

湿地是人类生存环境的重要组成部分,具有调节气候、调蓄洪水、维持地球化学循环和控制污染等环境功能和效益.在自然和人类干扰下,湿地正在经历着显著的变化,湿地变化必然引发环境变化.湿地变化所产生的气候效应研究成为我国湿地科学的重要研究方向之一.本文梳理了我国湿地变化在影响碳存储(排放)、区域气候方面的研究进展,据此,提出了加强湿地变化生态环境效应的过程机理研究、尺度效应和转换研究以及加强人工湿地研究应作为湿地科学未来重要研究方向的建议.

Wetlands has many important environmental functions and benefits,such as moderating climate,regulating hydrology,maintaining geochemical cycling,and degradation pollution. Influenced by natural and human activities,wetlands changed significantly. Wetland change will result in improving or weakening wetland functions,and inevitably bring about obvious environmental effect. Wetland change and resultant impacts on eco-environment have become one of the hottest fields in wetland science. Through analyzing domestic research findings,this paper reviewes recent findings on the impact on eco-environment of wetland change from view of carbon cycle,carbon emission,and regional climate. Finally,this paper pointed out that important direction of further research B focus on process,mechanism,scale effect and scale conversion of impact of wetland change on eco-environment,as well as constructed wetlands.
