二进制粒在旱涝序列相似性匹配中的应用

摘要

By using the binary to represent events in the drought and flodd sequence, this paper made definitions for the binary granular algorithm and the similarity matching of the binary granular event sequence. It also explained multi-level and full sequence matching algorithm in the binary granular event sequence. The effectiveness of the research was proved by experiment and its analysis, and a new method was provided for studying similarity of regional climate and local climate.%通过采用二进制数表示旱涝事件序列中的事件,描述了基于二进制信息粒的运算及二进制粒事件序列相似性匹配的相关定义,提出了基于二进制粒事件序列上的多层次全序列匹配算法及相关定义；经实验验证分析,说明了研究的有效性,为研究地域气候相似和局地小气候相似提供了新方法.
