[目的/意义] 搜寻意图是信息搜寻过程的起点，搜寻策略是搜寻行为的规划，两者的关联机制是搜寻行为动态发展规律的集中体现，研究搜寻意图和搜寻策略选择的关联机制有利于深入了解搜寻行为产生及变化的原因和过程。[方法/过程] 通过问卷收集搜寻意图与搜寻策略数据，使用UCINET研究不同意图下的策略选择偏好，使用SPSS modeler探寻不同意图下的策略组合，采用ROST CM对基于不同意图的信息偶遇现象进行研究。[结果/结论] 搜索和浏览是用户信息搜寻时最常使用的搜寻策略；不同的搜寻意图对应的用户搜寻策略选择偏好呈现明显差异，也表现出不同的搜寻策略组合模式；信息偶遇比较大概率地发生在信息查找、资源下载和建议咨询情境中。
[Purpose/significance] Seeking intention is the starting point of search process, seeking strategy is the planning of search behavior, and the correlation mechanism between seeking intention and seeking strategy selection is the reorientation of the dynamic development of search behavior. It is of great significance of exploring the correlation mechanism between information seeking intention and seeking strategy selection to deeply understand the causes and processes of the changing search behavior.[Method/process] This paper collected the data of seeking intention and seeking strategy through questionnaires, used UCINET to study the preference of strategy choice, used SPSS modeler to explore the most commonly used strategy combinations, and used ROST CM to study information encounter under different intentions.[Result/conclusion] Searching and browsing are the two most frequently used seeking strategies. Users have obvious differences in their preferences for different seeking strategies and different seeking strategy combinations corresponding to different seeking intentions. For the strategy of information encountering, it is more likely to occur in the situation of information searching, resource downloading, and advising and consulting.
