摘要: 近年来,湿地环境开发过程中出现了多种生态环境问题,由于多种开发方式和多种影响因素的共同作用,对湿地环境产生明显的累积效应,单一要素的环境评价和分析已满足不了湿地利用和保护的要求,亟需加强湿地环境累积效应研究。本文从累积效应研究的基础出发,提出湿地累积效应的概念和研究内容,界定湿地环境累积效应研究范围(空间和时间),并综述环境累积效应研究方法,阐明了目前研究的不足,最后指出了湿地环境累积效应的未来研究方向为:环境累积效应的途径、环境累积效应的长期监测和累积效应预测模型的建立。

Abstract: In recent years, there are many ecological environment problems happened in developing wetland environment. Because the combination of many development patterns and factors has cumulative effects on wetland environment, the environment assessment of simple element cannot meet the need of wetland protection and utilization. Therefore, it is necessary to emphasize the study on the cumulative effects of wetland environment. In this paper, the definition and content of wetland cumulative effects were developed, the spatial and temporal scope of these effects was identified, and the related study methods were reviewed. The deficiency of the current study was illustrated, and the directions for further study were put forward, including the path of environment cumulative effects, the long monitoring of the cumulative effects of wetland environment, and the construction of the prediction model of environment cumulative effects.
