摘要:

地域分异是地理学核心研究方向之一,水生态功能分区是地学分区面向生态环境领域的发展和应用。基于水生态分区的管理是流域水环境管理的趋势,流域水生态功能分区是建立中国新型水环境管理的基础。论文在界定水生态功能分区涉及的主要概念基础上,分析了湖泊型流域水生态系统的尺度,为湖泊型流域水生态功能分区体系的建立奠定了理论基础;根据分区的目的,建立了分区的原则和指标体系,研发了分区技术、结果验证校核方法;以巢湖流域为例,进行了一级至四级水生态功能分区,并对分区结果进行验证。湖泊型流域水生态功能分区有助于丰富地域分异规律研究,对水生态目标管理的理论与方法具有指导作用。

Abstract:

Spatial differentiation is one of the core research directions of geography. Aquatic ecoregion delineation is the development and application of geographic regionalization in the field of ecological environment. Management based on aquatic ecoregions is the trend of water environmental management in watersheds. Aquatic ecoregion is the foundation of future water environmental management in China. Existing work cannot meet the technical requirements of water quality management for aquatic ecosystem protection. Based on the analysis of the main concepts involved in aquatic ecoregion, this study analyzed the scale of aquatic ecosystem in lake-basins, and laid a theoretical foundation for the delineation of aquatic ecoregion system in lake-basins. Taking the Chao Lake Basin as an example, the method was used to delineate the aquatic ecoregion at four levels, and the results were validated. Aquatic ecoregion delineation of lake-basin is helpful for enriching the study of spatial differentiation of geographical regions, and has important implications for advancing the theory and methods of aquatic ecosystem target management.

Key words: lake-basin, aquatic ecoregion, levels, scale, Chao Lake Basin
