Abstract:

Building on the strategic guidance provided by the “Development of Scientific and Technological Innovation in Natural Resources”, this study explores the innovative development of a multi-technology integrated observation system for natural resource elements, focusing on the core area and ecological barrier of the middle and lower Yangtze River Basin.The research systematically addresses three critical constraints affecting regional observation network effectiveness: Ⅰ) Lack of systemic coupling due to single-element monitoring; Ⅱ) Data heterogeneity hindering cross-domain integrated analysis; Ⅲ) Lagging intelligent technology application limiting dynamic assessment capabilities.Breaking through traditional monitoring paradigms byintroducing the innovative “three-level gradient observation system”, the study pioneers a dimensional station network framework of “1+12+52”(comprehensive central station-regional stations-specialized stations), effectively bridging the research gap in basin-scale natural resource system coupling.Taking Huangshan Observation and Research Station for Land-water Resources as an example, multi-element collaborative monitoring has significantly enhanced data collection efficiency, enabling synchronous dynamic monitoring of hydrological, soil, and vegetation parameters.The innovation in the technical system leads to the development of a “coupling of elements-process simulation-effect assessment” observation paradigm, which markedly improves the analysis of ecological processes and the prediction of system responses.Practical applications demonstrate that the comprehensive observation network effectively resolves fragmentation issues in traditional monitoring, providing full-element, multi-scale data support for dynamic resource management in the Yangtze Economic Belt.The innovative design offers a scalable reference for building a “mountain-water-forest-farmland-lake-grassland-desert” life communities.The research outcomes substantially enhance regional ecological security early-warning capabilities and scientific decision-making levels, providing crucial technical support for modernizing China’s natural resource governance system.Implementation results show significant improvements in cross-departmental data interoperability and ecological risk prediction accuracy compared to conventional methods.
