Abstract
Value accounting of water in the Yellow River Basin is a key issue in managing local water resources in an efficient, equitable, and sustainable way. In view of the dubious current theories of water resource value, the value transfer of water resources, based on energy flow, is discussed from the perspective of eco-economics. An emergy analysis method is introduced to quantify both the sediment transportation value and social value, and a quantitative system of eco-economic value indicators is constructed. The water resource values of 66 cities in the Basin were calculated, and the GIS atlas was used to describe their spatial distribution. Eight typical cities were selected for the key analysis. The results show that: (1) Among the sub-items, the social value of water per unit is the largest, reaching 30.67 Chinese Yuan/m³, and the difference between the maximum and minimum is only 0.04%, which reflects the social equity of water resources. (2) The eco-environmental value inside the river is generally higher than that of industry, and it is verified that industrial water should not intrude the eco-environmental water in the river. (3) The unit agricultural value of water is the lowest among the sub-items, and the construction of water-saving agriculture should be carried out.
Highlights
Water is the foundation of biological existence, the indispensable resource of human life, and it provides the primary condition for the survival and development of all life [1]
Realization of water resource value is an important basis for rational allocation of water resources [3], and it is necessary to conduct value stream analysis of the water resource eco-economic system in the Yellow River Basin
The objective of this paper is to provide a new basis for the evaluation of water resource eco-economic value, where the basis of the value evaluation is to analyze the value stream of the water resource eco-economic system
Summary
Water is the foundation of biological existence, the indispensable resource of human life, and it provides the primary condition for the survival and development of all life [1]. The sharp contradiction between the supply and demand of water resources in the basin is mainly manifested in the following aspects: firstly, the current water supply has exceeded the carrying capacity; secondly, water resource shortages seriously restrict the sustainable development of both economy and society; thirdly, production water seriously intrudes the eco-environmental water inside the river, seriously threatening the health of the river, and, low water-use efficiency [2]. Rational allocation of water resources and alleviation of the contradiction between supply and demand are the main tasks in the management, development, and protection of the Yellow River. Realization of water resource value is an important basis for rational allocation of water resources [3], and it is necessary to conduct value stream analysis of the water resource eco-economic system in the Yellow River Basin.
