Abstract: 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.
