Abstract: Due to the mechanism of triboelectrification on the surfaces of graphite and gangue miner⁃ als，it is challenging to accurately obtain the polarization characteristics of graphite ore images and their background，making it difficult to precisely determine the comprehensive geophysical exploration direction for graphite ore. To address this issue，this paper proposes an integrated geophysical exploration method based on GIS technology and polarization imaging，using the Koukouertu area in Wutumeiren Township， Geermu City，Qinghai Province as the study region. The method employs the MapX component of the GIS re⁃ gional management platform to uniformly manage geological information within the mining area，reducing surveying distortion through graphic vectorization，achieving seamless zooming，and low-redundancy stor⁃ age. Spatial data layering techniques are utilized to divide geophysical exploration data into different layers， innovatively establishing a database that preserves spatial and attribute data. Based on hyperspectral remote sensing and aerial-space integrated prediction methods，we quickly identify the target and background po⁃ larization features of graphite ore images. Aerial imaging spectrometers and ground quasi-synchronous cali⁃ bration are used to acquire aerial-space hyperspectral data，facilitating the extraction of the comprehensive geophysical exploration direction for graphite ore.Application results demonstrate that at a polarization angle of 0°，the acquired images exhibit the highest brightness and clarity，with the most accurate analysis of the mining area's polarization characteristics. The fluid inclusions in the ore bodies of the study area mainly con⁃sist of CH4，with some inclusions containing N2，H2O，etc.，but no CO2. The fluids within graphite ores pre⁃ dominantly belong to intermediate-low temperature and intermediate-low salinity shallow metamorphic flu⁃ ids，with relatively scarce inorganic carbon. This research provides data support for determining the compre⁃ hensive geophysical exploration direction of graphite ores.
