The 8th symposium on fluid geoscience, mineral resources and environmental disasters reflects the formation and evolution of geological fluids, the enrichment and distribution of mineral resources, and the research progress and development trend of environmental disasters in recent years. The relevant papers of the 8th symposium regarding fluid geoscience, mineral resources and environmental disasters from 6 aspects, including the deep geological processes and mineral resources, the physicochemical techniques of geological fluid research, the fluid geochemical characteristics and seismicity, the occurrence characteristics and development status of geothermal resources, the accumulation characteristics, controlling factors and enrichment rules of geological resources, the fluid geoscience and geographical natural environment, were summarized. The results show that ① the generation and evolution mechanism, enrichment and migration mechanism of oil, gas and mineral resources, and the development of exploration and development technology are still the focus of the current research in the field of fluid geoscience, and the research content also pays more attention to the history and mechanism of resource generation and evolution; ② it is the current main trend to adopt diversified and more accurate new technologies to explore new fields with more complicated geological conditions, deeper burial and more difficult exploration and exploitation; ③ at present, the uncertainty of China's extreme natural disaster risk is affected by many natural, economic and social factors, and it shows an increasing trend; destructive earthquakes are in a period of frequent occurrence, and the sudden, abnormal and complex characteristics of natural disasters are also showing an increasing trend, therefore, it is urgent to improve China's natural disaster prevention and control capacity.

Ecological geology is an emerging interdisciplinary subject, studying the interaction, coordination and balance between geological, ecological and disaster environments driven by multi-sphere mutual feedback effects and human activities on the earth surface. Under the general background of ecological civilization construction in China, the ecological geological environment system is composed by ecological environmental system, geological environmental system and geo-hazard environmental system, which are intercoupling and interacting. The core issue of ecological geology lies in the balance of the eco-geological environmental system, and the prevention and control of disasters. Therefore, this paper proposes four major research frontiers of ecological geology and the eco-geological environmental system: (1) The structure and interaction mechanism of the eco-geological environmental system; (2) The mechanism and pattern of the dynamic balance of the eco-geological environmental system; (3) The symbiotic mutual feedback mechanism and progressive evolution process of ecological damages-soil and water disasters-geological disasters; (4) The dynamic detection, monitoring and early warning, as well as management and mitigation of eco-geological environment risks. The above four components are progressively and interdependently integrated to address the core issue of ecological geology. The proceeding of ecological geology should comprehend the connotation of ecology priority and green development, focus on eco-geological safety and disaster environment system issues, and implement the strategic principle of “firstly strengthening the ecological barrier, and then accelerating high-quality development, finally leading the world pattern”, thereby contributing to scientific and technical supports for the decision and implementation of national strategies such as ecological protection and construction of beautiful China.

In the past decade, learning from foreign countries experience, China has studied and developed environmental monitoring sensor technology; constructed fisheries eco-environment monitoring network; earned out studies on red tide, etc. environmental disaster early warning technology. Besides, our country has explored the water pollution effect on ecological system structure and function, toxicity of pollutants; the habitat restoration and wild species protection and recovery measures; and has gained remarkable progress on key emergency handling technology such as handling oil spill, chemical pollutants and heavy metals pollution accident, etc.. In view of the present policy orientation and research hot spot, the paper suggested to pay more attention to the construction of large scale national environment monitoring data network; to study on disaster early warning mechanism, biological strychnos of pollutents and their genetic variation rule at molecular level, and water environmental restoration and healthy aquaculture strategy, etc., so as to establish a solid foundation for the sustainable development of fishery in China.
