AI 中文摘要
引力与吸引体的质量成正比；因此，可以利用重力测量来探测地下质量的变化。在近地表区域，质量变化主要由储水量的变化驱动，这意味着重力测量能够直接提供关于水质量变化的信息。传统上，地下水和土壤水动态是通过需要直接安装到地下的点尺度仪器进行监测的。相比之下，重力测量是一种非侵入性方法，能够在更大的空间范围内整合信号。近年来，重力仪技术的进步显著提高了野外条件下的测量精度和长期稳定性，从而扩大了其在水文应用中的潜力。本综述总结了重力测量仪器的最新进展，并提供了用于地面测量的重力仪及其在水文学中应用的基本背景知识，旨在促进其更广泛的使用。此外，本文还概述了在水文学和水文地质学中成功应用重力测量来量化地下储水量变化、估算水文参数以及约束数值模型的研究。最后，对重力测量未来的发展及其潜在应用前景进行了展望。
英文摘要
Gravitational force is proportional to the mass of an attracting body; therefore, changes in subsurface mass can be detected using gravimetry. In the near subsurface, mass variations are primarily driven by changes in water storage, meaning that gravity measurements provide direct information on variations in water mass. Traditionally, groundwater and soil water dynamics are monitored using point-scale instruments that require direct installation into the subsurface. In contrast, gravimetry is a non-invasive method that integrates signals over a larger spatial extent. Recent advancements in gravimeter technology have significantly improved measurement accuracy and long-term stability under field conditions, thereby expanding their potential for hydrological applications. This review summarizes recent developments in gravimetric instrumentation and provides essential background on gravimeters used for ground-based measurements and their application in hydrology, aiming to facilitate their broader use. In addition, it presents an overview of studies in hydrology and hydrogeology that have successfully applied gravimetry to quantify subsurface water storage changes, estimate hydrological parameters, and constrain numerical models. A perspective on future advancement in gravimetry and resulting potential applications is given.
