Abstract:

The calculation of the physical quantity of aquatic ecological products is the basis for the accounting and realization of the value of aquatic ecological products. In order to objectively reflect the relationship between the value of aquatic ecological products and water cycle processes, this study took the Huangshui River Basin in the upper reaches of the Yellow River as an example, and calculated the physical quantity and value of aquatic ecological products (water resources supply, water resources stock, soil conservation, flood regulation and storage, and water quality purification) in the basin from 1986 to 2015 by means of multi-process simulation of the water cycle in the basin, scenario analysis, and socio-economic condition investigation. The value composition and spatiotemporal distribution pattern of aquatic ecological products were systematically analyzed. The results show that the total value of aquatic ecological products in the Huangshui River Basin from 1986 to 1995 was 60.481 billion yuan/a, which increased by 10.87% and 24.49% in 1996-2005 and 2005-2015, respectively. The contribution of water resources storage was the highest (66.59%-69.53%), followed by reservoir flood control, water supply, and water purification (accounting for 18.91%-23.54%, 5.08%-5.53%, and 4.77%-6.12%, respectively), and the contribution of soil conservation was negligible (0.02%). The value of aquatic ecological products in sub-basins usually decreased from the upstream to the downstream, but the values of aquatic ecological products have increased significantly in sub-basins with water conservancy projects. This study provides a theoretical and technical support for the management of water ecosystems in the upper reaches of the Yellow River.
