摘　　要：水利信息化专利是信息技术在水利领域应用的重要体现和产出,在水利工程管理和信息化建设过程中发挥着重要作用。以水利信息化专利数据为研究对象,提出一套基于专利数据的分析流程,对专利申请趋势、申请地域、技术领域等要素进行统计学分析,同时利用LDA主题模型识别水利信息化专利的主题与热点,揭示中国水利信息化领域的技术架构组成和发展趋势,为推进中国水利信息化学科规范化建设,促进水利信息化领域健康有序发展提供重要支撑。LDA主题模型将水利信息化领域专利划分为6个应用分类,即水利设备、工程施工、数据监测、水利预警、信息管理、调度分析。研究表明:信息管理主题的申请数量较多且持续增加,相关技术发展前景较好;水利预警主题热度较低,反映该主题是研究的薄弱点、短板,应提高该主题在水利信息化领域技术布局中的投入。Patents in water conservancy informatization represent the application and outcomes of information technology in the water sector,playing a crucial role in water engineering management and informatization development.Using patent data as the research object,this study proposed a patent-based analysis framework to statistically analyze key factors such as application trends,geographical distribution,and technological fields.Additionally,the LDA(Latent Dirichlet Allocation)topic model was employed to identify themes and hotspots in water conservancy informatization patents,revealing the technical structure and development trajectory of this field in China.The study provided vital insights to standardize academic construction in water conservancy informatization and promote orderly development.The LDA model categorized the patents into six application domains:hydraulic equipment,engineering construction,data monitoring,water conservancy warning,information management,and scheduling analysis.The findings reveal that patents in the information management category are numerous and steadily increasing,indicating promising technological prospects,whereas the water conservancy warning category shows lower activity,highlighting it as a weak area requiring greater investment in technical planning within this domain.
