Abstract:

Based on the demand for natural resource management in China, and adhering to natural resources science and earth system science theory, the national natural resource elements comprehensive observation network project has been active since 2020. This project takes environment types and natural resources localization as input and adheres to the working principles of innovation mechanism, coordination organization, green cooperation, open cooperation, and data sharing. As the second largest inland river basin in northwest China, the Heihe River Basin is at the core of the Silk Road Economic Belt. The resource and environmental problems in the basin are significant, and thus, there is an urgent need to carry out research in the Heihe River Basin. Cold and arid areas coexist in the basin; this basin has the typical characteristics in the upper, middle, and lower reaches of the basin. This river basin represents an ideal site for comprehensive observation and research. Based on the current observation and research in the Heihe River Basin, 13 observation stations were set up in different river basins and levels by three ways of integration, reconstruction and upgrading, and new constructions in blank space. The main types of land surface use, such as grassland, forest, river, lake, desert, wetland, and farmland in the Heihe River Basin were basically covered. Combining remote sensing observations and artificial sample plot investigation, a comprehensive observation network of natural resource elements in Heihe River Basin is constructed in this work. By establishing a unified operation, maintenance, and quality management system, the authenticity and reliability of the observation data are ensured. The comprehensive observation network of natural resources elements in Heihe River Basin permits a three-dimensional observation capacity, which can effectively obtain the key data, such as the coupling process, change trends, and speed between resources. This is of great significance to the improvement of the scientific management and strategic decision making related to the natural resources in Heihe River Basin. The study also provides an important reference for further studies and demonstrates the significance of the observation of and research into natural resources in other basins.

Key words: Heihe River Basin, natural resources management, integrated observation of space-air-ground, field observation stations, comprehensive observation network
