    第四纪地质学视角下地表基质调查进展与思考

    Progress and thought of ground substrate survey from the perspective of Quaternary geology

    • 摘要: 地表基质调查是自然资源综合调查的全新业务领域,对生态文明建设和区域经济高质量发展具有重要意义。文章结合国内外基础地质调查和土壤调查等领域的研究动态,梳理了地表基质的概念及分类,总结了地表基质调查在调查内容及深度、工作流程和方法等方面取得的进展,并基于第四纪地质学视角从地表基质理论方法、调查区域和成果总结等方面提出了思考及建议:第四纪地质学可为地表基质调查提供基础的地学理论框架,尤其有助于增进对砾质、砂质、土质和泥质等地表基质类型的科学认识;在调查区域选取方面,建议优先选取冲积平原区(如华北平原、三江平原)和大型沉积盆地(如汾渭盆地、四川盆地)等第四系覆盖区开展地表基质调查工作;在成果总结方面,应加强第四纪年代学研究和环境代用指标分析,提升对地表基质的形成及演化规律的整体认识,进一步完善图面表达形式,增强调查成果的可读性和科学性。

       

      Abstract: Ground substrate survey is a new field in integrated surveys of natural resources. It holds significant importance for the construction of ecological civilization and the high-quality development of regional economies. Based on advancements in related geological survey and soil survey, this paper reviews the progress in the ground substrate survey. It clarifies the concept and classification of ground substrate, and summarizes the survey content, investigation degree, work flow and methods. Furthermore, from the perspective of Quaternary geology, the article offers contemplations and recommendations regarding the principle, survey areas, and achievement expression. Quaternary geology can provide a fundamental geological theoretical framework for the ground substrate survey, especially in the ground substrate of gravel, sand, soil, and mud. In terms of regional selection, it is recommended to give priority to alluvial plains (e.g., North China Plain and Sanjiang Plain) and sedimentary basins (e.g., Fen-Wei Basin and Sichuan Basin) where the Quaternary deposits are widely distributed. The article also suggests strengthening the Quaternary research, including the geochronology and paleoenvironmental analysis, to deepen our understanding on the formation, evolution, and historical patterns of ground substrates. In addition, it calls for the diversification of map expression to strengthen the readability and scientificity.
