【摘要】：區(qū)域地質(zhì)調(diào)查是一項(xiàng)公益性質(zhì)的基礎(chǔ)地質(zhì)工作,幾十年來在支持我國經(jīng)濟(jì)發(fā)展上發(fā)揮著十分重要的作用。近年來,信息化技術(shù)和數(shù)據(jù)庫技術(shù)發(fā)展日趨成熟,這也推動了數(shù)字地質(zhì)填圖技術(shù)的發(fā)展,運(yùn)用計(jì)算機(jī)等信息化技術(shù)進(jìn)行區(qū)調(diào)工作優(yōu)勢明顯,已經(jīng)被廣泛應(yīng)用,應(yīng)用數(shù)字化地質(zhì)填圖技術(shù)有助于不同行業(yè)對地質(zhì)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(diào)工作的質(zhì)量和效率大有幫助。近年來,國內(nèi)的數(shù)字地質(zhì)填圖工作已經(jīng)逐步在地質(zhì)工作中推廣普及,但在系統(tǒng)設(shè)計(jì)和操作易用性方面仍存在一些不足,這對于區(qū)調(diào)工作的數(shù)字化發(fā)展產(chǎn)生了不利影響。本文結(jié)合黑龍江省戰(zhàn)備村等1:5萬區(qū)域地質(zhì)調(diào)查項(xiàng)目,總結(jié)了實(shí)際工作中的經(jīng)驗(yàn)與方法,同時(shí)結(jié)合數(shù)字地質(zhì)填圖技術(shù)的基本理論,總結(jié)出了項(xiàng)目工作過程中室內(nèi)、室外資料處理和1:5萬地質(zhì)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(zhì)填圖工作中的PRB過程,適合本項(xiàng)目工作區(qū)地質(zhì)特征的PRB字典庫設(shè)計(jì)及部分?jǐn)?shù)據(jù)表結(jié)構(gòu)設(shè)計(jì),地質(zhì)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(zhì)圖數(shù)據(jù)庫建設(shè)方面,使用數(shù)字填圖系統(tǒng)的建庫方法理論,完成了實(shí)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(zhì)圖空間數(shù)據(jù)庫建庫國家標(biāo)準(zhǔn),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(jié)構(gòu)設(shè)計(jì)。數(shù)字地質(zhì)填圖技術(shù)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(diǎn),本文結(jié)合地質(zhì)圖數(shù)據(jù)庫建設(shè)探討了對數(shù)據(jù)質(zhì)量的控制方法和生成實(shí)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(zhì)填圖的工作人員用以借鑒,提高數(shù)字地質(zhì)填圖效率,為高質(zhì)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.
