It is absolutely necessary to study classify, patterns and dynamic of the landscape of watersheds from the level of landscape, in order to get system knowledge for whole watershed and to provide foundation for landscape construction of the region, taken count of the close relationship between the landscape structure and its hydrological process, its pollution shifting process and suppuration of biodiversity.

流域的景观结构特点与流域的水文过程、污染物迁移过程及对生物多样性的支持功能密切相关，因此有必要从景观水平上研究流域的景观分类、景观格局与动态特征，以期获得对流域整体的系统认识，为开展以流域为单元的景观生态建设提供依据。
