【摘要】：在地質調查過程中,地質工作者經常采用地球化學數(shù)據(jù)的處理結果來進行巖石成分、大地構造等環(huán)境問題的研究,然而地球化學數(shù)據(jù)量大、種類繁多,各研究機構又獨自存儲和管理,對設備需求量極大,且易造成信息孤島。地球化學數(shù)據(jù)通常利用巖石地球化學圖解來進行分析和處理,但是圖解資料分散、格式多樣、精確度不高等問題也為地質研究工作帶來了極大的不便。云計算技術的海量數(shù)據(jù)處理、大規(guī)模計算、系統(tǒng)設備投入少、維護簡單等優(yōu)勢為地質研究工作提供了新的工作思路和出路。本研究以云計算技術為基礎,以巖石地球化學圖解服務為研究對象,通過對國內外研究現(xiàn)狀的分析和問題總結,提出了對基于云環(huán)境的巖石地球化學圖解服務平臺搭建的研究。在平臺架構設計方面,將其按服務類型劃分為虛擬化設施層、云圖解平臺服務層和云圖解應用服務層三個層面,虛擬化設置層的搭建為平臺提供了硬件環(huán)境支撐。在數(shù)據(jù)管理方面,收集整理巖石地球化學圖解資料,由專家確認其準確性并對其進行種類劃分。在云圖解應用服務層設計方面,根據(jù)巖石地球化學數(shù)據(jù)處理流程,將巖石地球化學圖解服務平臺中的服務劃分為圖解基礎服務和圖解計算服務等,明確了需求和功能劃分。針對巖石地球化學圖解的繪制特點,采用MSChart技術來提高圖解繪制精度;定義了圖解的數(shù)據(jù)模式,采用XSD技術定義和存儲圖解基本信息,便于平臺間的數(shù)據(jù)交換。搭建基于云環(huán)境的巖石地球化學圖解服務平臺,在一定程度上彌補了當前地球化學研究數(shù)據(jù)共享方面的空白,實現(xiàn)了用戶間的數(shù)據(jù)交流,消除了數(shù)據(jù)冗余,減少了計算和存儲資源的浪費,對當前的地球化學研究具有重要意義。
[Abstract]:In the process of geological survey, geologists often use the results of geochemical data processing to study environmental problems such as rock composition, geotectonics, etc. Each research organization has its own storage and management, which is in great demand for equipment and easy to cause information isolated islands. Geochemical data are usually analyzed and processed by rock geochemical diagrams, but the graphical data are scattered and have various formats. Problems such as low accuracy also bring great inconvenience to geological research work. Cloud computing technology for massive data processing, large-scale computing, system equipment investment less, The advantages of maintaining simplicity provide a new way for geological research. This study is based on cloud computing technology, and takes the service of rock geochemistry as the research object, through the analysis and summary of the current research situation at home and abroad. In the aspect of platform architecture design, it is divided into three layers according to service type: virtualization facility layer, cloud diagram platform service layer and cloud diagram application service layer. The construction of virtualization setup layer provides the hardware environment support for the platform. In the aspect of data management, we collect and sort out the lithogeochemical graphic data, Experts confirm its accuracy and classify it. In cloud diagram application service layer design, according to the process of processing rock geochemistry data, The services in the lithochemical graphic service platform are divided into graphic basic services and graphical computing services, and the requirements and functions of the services are defined. According to the drawing characteristics of the lithochemical diagrams, the MSChart technique is adopted to improve the accuracy of graphic rendering. The schematic data pattern is defined, and the basic information of diagram is defined and stored by XSD technology, which is convenient for data exchange between platforms. To some extent, it makes up the gap in data sharing in current geochemical research, realizes the data exchange among users, eliminates the data redundancy, and reduces the waste of computing and storage resources. It is of great significance to present geochemical research.
