    Simply discussion on the work of ground substrate survey: taking Hainan Island as an example

    • 摘要: 地表基质调查是当前自然资源调查监测体系中的全新领域,如何开展还缺乏统一的行动指南。在初步总结地表基质调查现状的基础上,提出从全国、大区、关键地段3个层次、分阶段组织开展全国地表基质调查的总体思路。结合海南岛地表基质发育的地质背景和赋存条件,就南方强风化区地表基质调查工作进行了实例分析。建议按照分区逐级调查与分类补充调查相结合、调查与研究并重的原则,开展海南岛全域—流域—重点区段不同层级地表基质调查。针对地表基质分类补充调查提出基础调查指标、特征调查指标和评价指标,强调热带强风化条件下海陆交互作用、表生地质作用和多圈层相互作用对地表基质的控制与影响。在查清海南岛地表基质现状和演化规律的基础上,开展地表基质的综合评价和区划,探索形成热带强风化区地表基质调查的技术方法。

       

      Abstract: Ground substrate survey,a whole new field of natural resources survey and monitoring system in the current situation,has not evolved into an unified guide line on action. In this paper,based on the preliminarily summarization of the current situation of ground substrate survey,we provide the overall thinking about organization and implementation of national ground substrate survey in stages and from national level,reginal level and key areas level. Also,having taken into account of the geological background of breeding ground substrate in Hainan Island,we take a case study on how to carry out the ground substrate survey in the southern strong weathering area. Complying with the principles of combination of survey by different area and stage and supplemental survey,and investigation being of equal importance as survey,we divided the organization of ground substrate survey for Hainan Island into three levels,such as all over the Island level,watershed level,key area level. For the supplemental survey of ground substrate,we proposed basic survey indexes,characteristic indexes and evaluation indexes with emphasizing the control and influence of land-sea interaction and supergene geological effect under tropics strong weathering condition. After unravelling the current situation and evolution law of ground substrate,it is necessary to carry out the comprehensive evaluation and regionalization of ground substrate. Based above,we explored and summarized the technical methods of ground substrate survey in tropics strong weathering area.
