Abstract
The traditional concepts of water resource development and utilization have caused serious hydrological and environmental issues in some regions. In addition, policy issues in China have led to a severe water crisis. The quantitative accounting of water resources is a theoretical approach to solving these problems. In this paper, 13 indicators were selected from four classes, including resources, the environment, society, and efficiency, and a case study of Jinan, Shandong Province, was performed using a set pair analysis model to calculate the water resource assets from 2011–2015. In previous methods of water resource accounting, the water quality was not considered; therefore, the loss coefficient of water resource assets was proposed to improve the reliability of accounting. According to the relationships among the unit price of water, water quantity, and water quality, physical and quantitative accounting methods were used to create water balance sheets from 2011–2015. The calculation results showed that the physical change in water resource assets in Jinan City was −30 million m 3 , and water resource assets initially increased and then decreased. In 2011, 2012, 2013, 2014, and 2015, water resource assets totalled 36.5 million USD, 45.9 million USD, 66.7 million USD, 35.5 million USD, and 37.5 million USD, respectively (at 6.4588, 6.3125, 6.1932, 6.2166, 6.2284 USRMB, respectively). This initial accounting provides quantitative and physical support for the improved management of water resources.
Highlights
Water is the source of life, a key to production, and the basis of ecology [1]
China has not had a mature economic measure to measure the level of regional water resources development
Physical and quantitative accounting of the water resource assets in Jinan City was performed based on the availability of data and the actual needs of local water resource management
Summary
Water is the source of life, a key to production, and the basis of ecology [1]. In recent decades, humankind has not realized the importance of water resources [2] and has underestimated their role [3], and overexploitation and pollution have seriously threatened and hindered human survival and development. People have underestimated the calculated value of a portion of water resources. The reduction in the value of resources caused by resource consumption in socio-economic activities has not been reflected in national economic accounting; the external costs of socio-economic activities are underestimated, and this fails to completely reflect the comprehensive achievements of human society in its development [4]. In this context, the concept of “the sustainable development of water resources” was proposed. Determining how to evaluate the development and sustainability of regional water resources has become an issue that scientists around the world have relentlessly explored [5,6]
