    黄河三角洲地面沉降研究进展与未来展望

    Research Progress and Future Prospects of Land Subsidence in the Yellow River Delta

    • 摘要: 黄河三角洲是我国成陆时间最短的大型河口三角洲,由于其发育背景特殊、地质环境系统不稳定以及人类活动影响,地面沉降较为显著,引发了诸多环境问题,对自然环境和社会经济发展产生了严重威胁。从监测技术和成因机理角度出发,系统综述了黄河三角洲地区的地面沉降现状:①黄河三角洲地面沉降受新生地层自然压实、人为建筑重力压实、河流陆源输入减少、地下水与卤水开采、石油天然气开采以及海洋动力作用相对增强等多重因素影响,需要更详细、更系统的研究,特别是定量分离人为与自然因素在地面沉降的贡献方面,需要与其他学科如地质、岩土、力学、数学等交叉进行综合定量分析;②黄河三角洲地面沉降的长时空尺度的持续监测与分析、历史周期分析与未来判断分析需加强,尤其要重视海陆相互作用对地面沉降的长期和短期影响的研究;③地面沉降勘查、监测和精度研究及沉降评估和环境影响监测研究,尤其是海岸带退蚀与地面沉降之间的耦合关系等问题仍待深入。在今后研究黄河三角洲地面沉降的过程中,应更加注重理论模型的深入探究和新技术方法的实践,机理研究应扩展至多种模型研究;预测灾害时,应扩展到与地面沉降问题较为紧密的地面开裂、断层以及地裂缝等研究上。此外,还应对地面沉降的社会经济影响和环境影响等方面做出更多探索和实际应用。全面系统深入地了解黄河三角洲地面沉降现象,可为有效地实施三角洲生态保护和资源开发提供理论依据,具有重要的科学意义和社会经济价值。

       

      Abstract: The Yellow River Delta is a large estuarine delta with the shortest land formation time in China. Due to its special development background, the instability and vulnerability of the geological and environmental systems and the impact of human activities, the land subsidence is relatively significant. This has caused many environmental problems and posed a serious threat to the natural environment and regional socio-economic development. This study systematically summarizes the current situation of land subsidence in the Yellow River Delta region from the perspectives of monitoring technology and cause mechanism. It is pointed out that: ① The land subsidence in the Yellow River Delta is affected by a variety of factors, such as the natural compaction of nascent strata, gravity compaction of anthropogenic constructions, the reduction of riverine land source inputs, the exploitation of groundwater and brine, the exploitation of oil and natural gas, and the relative enhancement of oceanic dynamics. More detailed and systematic studies are needed, especially to quantitatively separate the contribution of anthropogenic and natural factors in ground subsidence. Comprehensive quantitative analyses are needed at the intersection of other disciplines such as geology, geotechnics, mechanics and mathematics. ② It is worthwhile to strengthen the continuous monitoring, historical cycle analysis and future judgment analysis of the land subsidence in the Yellow River Delta over a long period of time and spatial and temporal scales, especially to pay more attention to the research on the long-term and short-term impacts of sea-land interactions on land subsidence. ③ Investigation and research on land subsidence, monitoring of subsidence and its accuracy, and research on the relationship between subsidence assessment and environmental impacts, particularly the coupling relationship between coastal zone erosion and land subsidence, still need to be deepened. In the future study of ground subsidence in the Yellow River Delta, more attention should be paid to the in-depth investigation of theoretical models and the practice of new technical methods. The mechanism study should be extended to a variety of modeling studies. When predicting disasters, the research should be extended to ground cracking, faults and ground fissures, which are more closely related to the problem of ground subsidence. In addition, more explorations and practical applications should be made on the socio-economic and environmental impacts of ground subsidence. A comprehensive, systematic and in-depth understanding of ground subsidence in the Yellow River Delta will provide a theoretical basis for the effective implementation of ecological protection and resource development in the delta. It has important scientific significance and socio-economic value.
