中文摘要:
      丹汉江流域位于汉江中上游,是丹江口水库的主要水源区,其水质的优劣直接关系着国家南水北调中线工程的成败,因此对该流域的非点源污染研究显的尤为重要。通过查阅文献,总结了该流域泥沙和养分在不同空间尺度下的输移特征,归纳了多种负荷估算方法和模型应用进展,从源头、过程和末端3个方面阐述了水土以及养分流失的控制措施和生态补偿研究进展。并指出当前非点源污染源及污染过程和输移特征尚不清晰、应用模型较少且自主建立模型鲜见、污染控制与管理措施零散等问题。未来需要不断加强资料的系统监测,探明该流域非点源污染种类、来源及负荷,提高应用模型种类和精度,建立流域土地、水域最优开发和管理模式,逐步完善定量化研究与控制体系。
英文摘要:
      The Danjiang and Hanjiang River Basin, located in the middle and upper reaches of the Hanjiang River, is the main water source of the Danjiangkou Reservoir. Its water quality determines the success or failure of the National South-North Water Transfer Project. Therefore, the study of non-point source pollution in this basin is of grave importance. By reviewing the literatures, we summarized the transport characteristics of sediments and nutrients in different spatial scales in the basin, compared various load estimation methods and model application progress of the non-point source pollution, and expounded the control measures of water, soil and nutrient loss, as well as the research progress of ecological compensation from three aspects of the source, process and end control. It is found that the sources, process and transport characteristics of current non-point source pollution are still unclear. There are few application models and even fewer models developed by individuals, and the pollution control and management measures are scattered. In the future, it is necessary to continuously strengthen the systematic monitoring of data, to identify the types, sources and loads of non-point source pollution in the basin, as well as to improve the type and accuracy of the application models, so as to establish optimal development and management methods for the land and water in watershed, and improve the quantification research and control system.
