摘要: 就黄河断流对河口空间场后效所涉及的地理要素的演变,以所建河口演变概念-遥感信息系统,分析研究了黄河口近期演变的互关联信息基础,并依据研究目标的信息需求分析(IRA)与水下地貌趋势面分析的结果,阐述了河口空间场诸种反馈信息、变异中直观信息及隐伏信息.Abstract: The evolvement of geographical factors related to the Huanghe River zero flow's aftereffect feedback to its estuary spatial field is discussed.Based on the built estuary evolvement-remote sensing conceptual system,the correlative information basis of the recent estuary evolvement is analyzed.According to the result by the information requirement analysis(IRA)of the research target and the trend surface analysis of underwater geomorphology,the feedback information of the estuary spatial field,the intuitionistic and hidden information in variation are discussed.
