The shallow water resources of Zhuhai-Shenzhen area in southern Guangdong Province have been polluted heavily due to different causes. The shortage of freshwater resources has resulted in the tightness of the civil water and industrial water supply and restricted the development of industry. In order to solve the problem, the aerogeophysical survey techniques (aeromagnetic survey, airborne electromagnetic survey and airborne gamma ray survey) were applied in this area in recent year. On such a basis, the distribution of the transgression and the freshwater was detected, and the shallow water quality and the ground hot water resource potential were evaluated. The results obtained prove to be very useful in the scientific evaluation of the shallow water resource environment.
