遥感技术在青岛市城市地质调查中的应用

    APPLICATION OF REMOTE SENSING TECHNOLOGY TO URBAN GEOLOGICAL SURVEY AT QINGDAO CITY

    • 摘要: 遥感技术可运用于地质调查、城市空间拓展、自然资源开发、生态环境保护和城市安全等多个领域,为城市地质工作提供更为宏观和直观的数据支撑。通过多期高精度遥感影像分析,建立了胶州湾地质单元遥感解译标志,重新厘定了胶州湾区域地质图,查明了环胶州湾人工填土分布及面积,初步估算出青岛市主城区0~10、10~30、30~50、50~100 m深度地下空间资源量,提出10~50 m是青岛市地下空间拓展的主要深度。遥感技术为城市地质问题解决和城市空间扩展提供了技术支持,在青岛城市地质调查中发挥了巨大作用。

       

      Abstract: Remote sensing technology is now efficiently used in urban geological survey. It may provide more macroscopic and intuitive data support for urban geological mapping and specific investigations of some geological problems. In the Project on Urban Geological Survey of Qingdao City, the method of remote sensing is widely used and has achieved a lot. Firstly, based on the multi-period high accuracy remote sensing images, the remote sensing interpretation marks for Jiaozhou Bay are established and the regional geological map of Jiaozhou Bay recompiled. Secondly, the distribution of artificial reclaimed land around Jiaozhou Bay is identified. And the third, a preliminary estimation of underground space resources is made available with remote sensing data for the depth of 0~10 m, 10~30 m, 30~50 m and 50~100 m respectively of the main urban area of Qingdao city. It is proposed that 10~50 m underground is the potential layer for expansion of underground space. Our practice demonstrates that the results are very useful to realize the purpose of geological survey, to improve the work efficiency, and to ensure the integrity and accuracy of results. The remote sensing technology may also provide references for solving of some specific urban geological problems.
