[目的/意义] 大型科研仪器作为科技资源共享服务的核心基础载体，承担着繁重的科学测试分析与理论实证的重任，其分析测试内容能反映区域的当前技术发展水平和趋势，因此对大量的分析测试内容进行分析从而绘制区域技术创新空间格局的演变图谱，不仅为管理部门制定科技发展规划提供指引路标，而且还能发现科研领域相互倾扎的现象，及时调整发展策略。[方法/过程] 对区域内的大型科研仪器分析测试服务数据进行语义文本聚类、概念树以及连接强度矩阵，构建技术主题演化模型，尝试对区域内技术创新时空格局演变进行观测，基于数据分析结果摸清技术创新发展规律。[结果/结论] 分析结果与当前区域内技术创新发展趋势一致，能摸清现阶段内区域的技术发展趋势，对于科技管理部门制定政策具有较好的指向性与指导性。

[Purpose / Significance] As the core basic carrier of scientific and technological resource sharing services, large-scale scientific research instruments undertake the heavy task of scientific test analysis and theoretical demonstration. Their analysis and test contents can reflect the current level and trend of scientific and Technological Development in the region. Therefore, a large number of analysis and test contents are analyzed to draw the evolution map of the spatial pattern of regional scientific and technological innovation, which not only provides a guide for the management department to formulate the scientific and technological development plan, also can finds the phenomenon of mutual entanglement in the scientific research field and adjust the development strategy in time. [method / process] Through on the semantic text clustering, concept tree and connection strength matrix computation, the analysis and test service data of large scientific research instruments in the region is organized to build a technology theme evolution model, which can observe the evolution of the space-time pattern of scientific and technological innovation in the region, and finds out the development law of technological innovation based on the data analysis results. [Results / Conclusion] the analysis results are consistent with the current innovation and development trend in the region. It can find out the trend of scientific and technological activities in the region at the current stage, and has accurate direction and guidance for the scientific and technological management department to formulate policies.
