面向流域防洪安全的态势图谱构建及可视化方法

为充分利用防洪安全领域积累的监测数据，准确理解防洪安全态势，形成科学的综合决策，通过融合态势感知相关理论，提出面向流域防洪安全的态势图谱构建及可视化方法。从时空对象的特征、关系和行为入手，结合态势理论本体方法，针对流域防洪安全问题，厘清了相关的态势感知概念，构建了防洪态势指标体系，提出了态势图谱建模及可视化方法，并介绍了该理论在丹江口库区的应用，对态势感知理论在防洪安全等领域的应用具有借鉴意义。

Construction and visualization methods of situation map for flood control in river basin

In order to make full use of the accumulated monitoring data in the field of flood control security, accurately understand the situation of flood control security and form a scientific comprehensive decision, the construction and visualization methods of situation map for the flood control security of river basin was proposed. From characteristics, relationships and behaviors of spatial-temporal objects, based on the ontological method of situational theory, this study clarified the concept of relevant situational awareness to built up an indicator system of flood control situation and put forward the trend graph modeling and visualization methods, for the flood control security of river basin. Finally, the proposed methods were applied in the Danjiangkou Reservoir Basin, which has enlightenment and reference significance in the flood control security.
