摘要: 根据海岸带生态保护修复、重大工程地质安全和国土空间规划的需求，本文基于在津冀沿海地区的海岸带综合地质调查项目，建立了一套适合海岸带综合地质环境调查与监测的技术方法体系。该技术方法体系集空基遥感和无人机监测、陆基定点监测、滩浅海两栖船和无人艇平台移动监测、海洋水动力单指标和综合观测站、实验测试及数值模型研究等技术于一体。依托该技术，在津冀沿海建立了“空陆海”综合地质调查监测体系，可开展海岸带地层结构、活动断裂、地下水、地面沉降、海洋水动力、侵蚀淤积等调查监测和资源环境综合地质调查评价工作，为海岸带生态保护修复、重大工程地质安全等提供科学数据。综合调查和观测体系体现了当前调查技术的发展趋势和方向，具有一定的先进性和前瞻性，可在全国各地海岸带调查工作中进行推广和应用。Abstract: According to the requirements of ecological protection and restoration, geological security of majorengineering and spatial planning, based on the comprehensive geological survey project in Tianjin and Hebeicoastal area, a system of technical method suitable for comprehensive geo- environment investigation andobservation is established. The system integrates space- based remote sensing and UAV(Unmanned AerialVehicle) monitoring, land- based fixed- point monitoring, movement monitoring of amphibious ship andunmanned ship, single index and integrated observation station of marine hydrodynamics, experimental test andnumerical model research and so on. Based on this technology system, the "atmosphere-land-sea" comprehensiveinvestigation and observation system is established in Tianjin and Hebei coastal zone, which can be used to carryout Investigation, monitoring and comprehensive geological survey and evaluation of resources and environmentin coastal zone, such as stratigraphic structure, active fault, groundwater, land subsidence, marine hydrodynamics, erosion and deposition and so on. These works provide scientific data for ecological protection, restoration ofcoastal zone and geological safety of major projects. The comprehensive investigation and observation systemreflects the developing trend and direction of current survey technology, and has certain advanced andprospective features. It is worthy of wide application in coastal area survey in all parts of the country.
