摘 要:湿地生态系统水环境质量时空演化及其影响因素分析,是湿地理论和应用研究的热点领域。本文在总结国内外研究工作现状的基础上,探讨并构建了湿地水环境质量时空分异的影响因子分类体系,并对不同因子的湿地水环境效应研究特征进行了初步的归纳和总结。结果显示,自然因子是湿地水环境演化的背景约束因子,人为活动主导下的生产和消费过程是湿地水环境劣化的主导因子。采用工程和管理措施,遏制湿地水环境劣化趋势,是湿地管理的核心任务,但其衍生的负面效应应当引起关注。现阶段湿地生态系统水环境时空演化特征及成因研究工作缺乏整体性和集成性,综合影响因子构建和景观生态特征的湿地水环境效应研究是该领域研究工作逐步走向综合和集成的重要环节。The study on the spatiotemporal evolvement of wetland ecosystem water environmental quality and its related affecting factors is one of the hotspots in theoretical and applied wetland research.Based on the previous researches,this paper analyzed the spatiotemporal differentiation of wetland water environmental quality,constructed a classification system of related affecting factors,and summed up the characteristics of these factors in affecting wetland water environmental quality.Natural factors were served as the background constraint dimension in the evolvement of wetland water environment,and the anthropogenic processes of production and consumption were taken as the dominant factors causing the deterioration of wetland water environment.To adopt engineering and management measures to control the deterioration of wetland water environment would be the core mission of wetland management,but the potential accompanying negative effects should not be neglected.Up to date,the researches on the features and causes of the spatiotemporal evolvement of wetland water environmental quality are lack in integrity and integration.To address this problem,it would be a key issue to integrate the construction of a framework of related affecting factors and the research of landscape ecological characteristics of wetland water environment.
