Abstract: The construction of a comprehensive observation system for natural resource elements is an important measure for the Ministry of Natural Resources to fully implement Xi Jinping’s ecological civilization thought, fulfill the development concept of a life community of mountains, waters, forests, farmland, lakes and grassland, and conduct the “two unification” management of natural resources. This basic, public welfare, and urgent construction project is of significant importance in solving the problems of the shortage of long-term and continuous positioning observation research of natural resources, predicting the insufficient support of resources and environmental data, realizing the comprehensive division of natural resources as the management units, evaluating the comprehensive carrying capacity of resources, studying the process of coupling and balance among resources, prejudging the ecological evolution trend of resources and environment, and optimizing the spatial structure of natural resources. Natural resources survey, monitoring and observational research are the main means to obtain the current situation of natural resources and predict the future status. The natural resource survey and monitoring system is relatively complete, while the observational research system is relatively unsystematic, and data accumulation is relatively insufficient in China. In order to preferably build a comprehensive observation system for natural resource elements, the authors in this paper have put forward some suggestions from UVA remote sensing observations, data fusion and natural resources value. The UVA remote sensing observations and oblique photogrammetry should be fully utilized for stereoscopic observation of natural resources. The data fusion of natural resource elements should be developed based on the fusion experience of the research on precipitation, land surface, sea surface and 3D cloud meteorological multi-variate data. Besides, the asset value account of natural resources should be based on the evaluation experience of forest resource ecological service value. These suggestions could provide some reference for the comprehensive observation system of natural resource elements.
