摘要
地质遗迹是自然资源的重要组成部分,妥善处理好高城镇化水平区域的地质遗迹保护与利用的关系,是推动地质文化村建设和新型城镇化高质量发展的生态措施之一。天津市的地质遗迹保护与利用工作因存在调查程度低、家底不尽清晰、分类方案不够规范、缺乏整体评价等问题,未能有效开展。基于对天津市全域地质遗迹调查的最新数据和对以往调查成果的整合梳理,按照《地质遗迹调查规范》(DZ/T 0303—2017)对天津市的地质遗迹进行了类型划分,对其科研价值、观赏价值、保护价值进行了定性分析,采用专家打分和层次分析相结合的方法进行定量评价和等级划分。研究结果表明:天津市重要地质遗迹可分为基础地质、地貌景观和地质灾害等3大类;发育有地层剖面、重要岩矿石产地、岩土体地貌、构造地貌、水体地貌、海岸地貌以及地质灾害遗迹等7类;进一步可分为层型(典型剖面)、典型矿床类露头、侵入岩地貌、碎屑岩地貌、碳酸盐岩地貌、湿地、飞来峰、断层崖、海积地貌、地面沉降等10亚类。通过综合分级评价,认为其中达到世界级标准的有4处,国家级3处,省级8处。上述研究结果可为天津市地质遗迹保护与科学利用提供参考。
Geological heritage is an important part of natural resources.Properly handling the relationship between protection and utilization of geological heritage in a high urbanization level area is one of the ecological measures to promote the high-quality development of new urbanization.However,the low level of geological heritage survey,unclear family background,lack of standard classification scheme and overall evaluation restrict the effective development of geological heritage protection and utilization in Tianjin.Based on the latest data of the whole Tianjin geological heritage survey,and through the integration of previous geological heritage survey results,this paper classifies the types of geological heritage according to the Specification for Geological Heritage Survey(DZ/T 0303—2017).The scientific research value,ornamental value and protection value are qualitatively analyzed,and the quantitative evaluation and grade division are carried out by combining expert scoring and AHP.According to the classification scheme in the Specification for Geological Heritage Survey(DZ/T 0303—2017),the important geological heritages in Tianjin are divided into 3 main categories:basic geological category,geomorphic landscape category and geological disasters,7 categories:stratigraphic section,important rock and ore producing areas,rock and soil geomorphology,structural geomorphology,water geomorphology,coastal geomorphology and geological disaster heritages,10 subclasses:stratotype(typical section),typical deposit outcrop,intrusive rock landform,clastic rock landform,carbonate rock landform,wetland,klippe,fault cliff,marine landform and land subsidence.The comprehensive evaluation and analysis indicate that there are 4 world-level,3 national-level and 8 provincial-level geological heritages in Tianjin.The above research is expected to provide references for the protection and utilization of geological heritages in Tianjin.
