珠海五年探地成果出炉：新发现2处地热田，面积逾3平方公里

Core Insights - The Zhuhai Urban Geological Survey project, which took five years to complete, has successfully unveiled the underground resources of Zhuhai, including geothermal fields and water resources, providing critical support for urban planning and geological safety [1][2] Group 1: Geological Resources - The survey identified 15 emergency underground water sources and 328 geothermal anomaly points with temperatures exceeding 25°C, including a newly discovered geothermal field of approximately 3.37 square kilometers with a maximum temperature of 79.1°C [2] - The freshwater exploration on islands such as Dawan Mountain and Dong'ao Island resulted in a total freshwater resource of 438 cubic meters per day, with significant yields from specific drilling sites [2] Group 2: Geological Hazards and Infrastructure - The survey mapped the distribution of major fault lines and identified 62 isolated rock groups, providing essential data for disaster prevention and major engineering project planning [2] - The study also detailed the distribution of soft soil and ground subsidence, with a notable area of approximately 966 square kilometers in Zhuhai's western region, highlighting subsidence rates and their implications for urban infrastructure [3] Group 3: Data Integration and Technological Advancements - Zhuhai has established a comprehensive urban geological database integrating 90 types of results from various surveys, including 13,000 borehole data entries, and developed a three-dimensional geological model [3] - The city has created a geological information service and decision support system, enhancing data sharing, government decision-making, and geological monitoring capabilities [3]
