摘要： 基于突发事件环境的动态特性与关系特性，定义突发事件关系位概念，讨论关系位的风险入侵机制、颗粒特征与分辨特征，给出关系位的可分辨准则。水库防汛水位调度系统实例说明了关系位原理的有效性与工程实用性。关系位理论是多学科交叉融合的结果，为突发事件与应急管理提供一种新的研究思路。

Abstract: This paper defines the concepts of emergency relation niche based on the dynamic and relative characteristics in emergency environment, discusses the risk intrusion mechanism, granular and discernible characteristics of relation niche, and presents the discernible rule of the relation niche. The example of reservoir flood prevention water level operation system shows the validity and engineering practicability of the relation niche theory. The relation niche theory results from syncretizing multiple disciplines and utilizing cross-fields technology and method, and provides a new idea and method to study the emergency and the emergency management.

Key words: emergency, relation niche, risk intrusion, granularity degree, discernibility degree
