【摘要】：區(qū)域地質調查是一項公益性質的基礎地質工作,幾十年來在支持我國經(jīng)濟發(fā)展上發(fā)揮著十分重要的作用。近年來,信息化技術和數(shù)據(jù)庫技術發(fā)展日趨成熟,這也推動了數(shù)字地質填圖技術的發(fā)展,運用計算機等信息化技術進行區(qū)調工作優(yōu)勢明顯,已經(jīng)被廣泛應用,應用數(shù)字化地質填圖技術有助于不同行業(yè)對地質類信息的共享使用,也有助于對所掌握數(shù)據(jù)的更新、管理,對提高區(qū)調工作的質量和效率大有幫助。近年來,國內(nèi)的數(shù)字地質填圖工作已經(jīng)逐步在地質工作中推廣普及,但在系統(tǒng)設計和操作易用性方面仍存在一些不足,這對于區(qū)調工作的數(shù)字化發(fā)展產(chǎn)生了不利影響。本文結合黑龍江省戰(zhàn)備村等1:5萬區(qū)域地質調查項目,總結了實際工作中的經(jīng)驗與方法,同時結合數(shù)字地質填圖技術的基本理論,總結出了項目工作過程中室內(nèi)、室外資料處理和1:5萬地質圖數(shù)據(jù)庫建庫這幾方面的常見問題和處理方法。具體的研究內(nèi)容包括數(shù)字地質填圖工作中的PRB過程,適合本項目工作區(qū)地質特征的PRB字典庫設計及部分數(shù)據(jù)表結構設計,地質圖空間數(shù)據(jù)庫建庫方法,數(shù)據(jù)精度控制,剖面自動生成等問題。在地質圖數(shù)據(jù)庫建設方面,使用數(shù)字填圖系統(tǒng)的建庫方法理論,完成了實際材料圖中自動為要素類數(shù)據(jù)賦值、空間數(shù)據(jù)屬性自動繼承,輸入空間屬性數(shù)據(jù)等建庫工作。按照1:5萬區(qū)域地質圖空間數(shù)據(jù)庫建庫國家標準,完成了1:5萬戰(zhàn)備村等兩幅空間數(shù)據(jù)庫的建庫工作,探討了適用于本工作區(qū)的工作方法和數(shù)據(jù)結構設計。數(shù)字地質填圖技術優(yōu)于傳統(tǒng)區(qū)域填圖方法,但不可避免存在一定的缺點,本文結合地質圖數(shù)據(jù)庫建設探討了對數(shù)據(jù)質量的控制方法和生成實測剖面圖等方面存在的問題,通過研究分析這方面的問題,可以為更多參與數(shù)字地質填圖的工作人員用以借鑒,提高數(shù)字地質填圖效率,為高質量完成填圖工作提供保證。
[Abstract]:Regional geological survey is a commonweal basic geological work, which plays a very important role in supporting the economic development of our country in recent decades. In recent years, the development of information technology and database technology has become more and more mature. This has also promoted the development of digital geological mapping technology. The use of information technology such as computers for regional mapping has obvious advantages and has been widely used. The application of digital geological mapping technology is helpful to the sharing and use of geological information in different industries. It also contributes to the updating and management of available data, and to the improvement of the quality and efficiency of regional mapping. In recent years, digital geological mapping in the country has been gradually popularized in geological work, However, there are still some deficiencies in system design and operational ease of use, which have a negative impact on the digitization development of regional geological work. This paper summarizes the experience and methods in practical work, and combines with the basic theory of digital geological mapping technology, sums up the indoor work of the project, Common problems and processing methods in outdoor data processing and 1: 50 000 geological map database construction. The specific research contents include the PRB process in digital geological mapping. The design of PRB dictionary database and part of data table structure are suitable for the geological features of the work area of the project, the method of building geological map spatial database, data precision control, section automatic generation, etc. In the aspect of geological map database construction, Based on the theory of building database of digital mapping system, the automatic assignment of element class data and the inheritance of spatial data attributes in the actual material map are completed. According to the national standards for the establishment of the spatial database of the 1: 50,000 regional geological map, the construction of two spatial databases, such as 1: 50,000 war readiness villages, was completed. The working method and data structure design suitable for this work area are discussed. The digital geological mapping technique is superior to the traditional regional mapping method, but it inevitably has some shortcomings. Based on the construction of geological map database, this paper discusses the control methods of data quality and the problems existing in the generation of measured profiles, and analyzes the problems in this respect through research and analysis. It can be used for reference by more people involved in digital geological mapping, improve the efficiency of digital geological mapping, and guarantee the completion of mapping work with high quality.
