Embodiment 1

[0060] figure 1 It is a flow chart of the implementation steps of the water price calculation method based on the cost structure of the water supply project provided by the present invention. refer to figure 1 As shown, the water price calculation method based on the cost structure of the water supply project provided in this embodiment specifically includes the following steps:

[0061] S101: Determine the surplus water volume of the water supply project.

[0062] By determining and distinguishing whether there is surplus water in the water supply project, it is necessary to determine the necessity of adopting the cost structure water price system.

[0063] Surplus water volume (also known as surplus water supply capacity) refers to the difference between the design water supply volume of the water supply project during the operation period and the annual design water demand of this level, which is expressed as the design water supply volume and design water price of the wa...

Embodiment 2

[0117] This embodiment takes the main project of diverting the Yellow River in the central part of Shanxi Province as a cost structure water price calculation application example to further describe in detail the application and implementation of the technical solution of the present invention:

[0118] The main task of the main project of the Yellow River Diversion Project in the central part of Shanxi Province is to solve the industrial and agricultural production and domestic water use in 16 counties (cities, districts) in Xinzhou, Luliang, Linfen and Jinzhong, and provide water support for the transformation and development of the region. According to the "Preliminary Design Report of the Yellow River Diversion Project in Central Shanxi Province" (2012, referred to as the "Preliminary Design Report"), the project draws water from the reservoir area of ​​the Tianqiao Hydropower Station on the main stream of the Yellow River North, and then pumps water through the first-level ...

Embodiment 3

[0151] This embodiment provides a water price calculation system based on the cost structure of a water supply project, which specifically includes a water quantity judgment module, a first calculation module, a pricing element selection module, a water price system selection module, a second calculation module and a third calculation module.

[0152] The water volume judging module is used to judge the surplus water volume of the water supply project.

[0153] By determining whether there is surplus water in the water supply project, it is necessary to determine the necessity of adopting the cost structure water price system.

[0154] Surplus water quantity (also known as surplus water supply capacity) refers to the difference between the design water supply quantity of the water supply project during the operation period and the annual design water demand of this level, which is expressed as the design water supply quantity (capacity) of the water supply project in the curren...

Abstract

The invention provides a water price calculation method and system based on the cost structure of a water supply project, and particularly comprises a cost structure water price system. The water price calculation method specifically comprises the steps of distinguishing the water demand within the design quota and the water demand beyond the design quota of the water supply project, and clarifying the rights and interests priority and payment responsibility; respectively selecting pricing elements of the two water demands, and calculating the feasible water price applicable to the water demand within the design quota and the small marginal water price applicable to the water demand beyond the design quota, thereby forming the cost structure water price system of the invention. According to the invention, the water supply project is facilitated to start from guaranteeing the water demand within the design quota and obtaining water supply benefits within the design quota in the runningphase, enables water users beyond the design quota to obtain water utilization net benefits by using the spare water supply capacity, enables the water supply project to increase the water supply netbenefits and improve tax and fee income of the government, thereby realizing a win-win situation of the three parties, and enabling the water supply capacity of the project to be fully played. In addition, the water utilization contradiction is avoided through clarifying the rights and responsibilities between responsibility subjects.

Description

technical field [0001] The invention belongs to the technical field of project water supply pricing, and in particular relates to a water price calculation method and system based on the cost structure of a water supply project. Background technique [0002] The actual water sales volume of large-scale water supply projects, especially water diversion projects, is generally significantly lower than the design scale for a long period of time in the early stage of operation, and there is more surplus water supply capacity. For example, diverting the Yellow River to Qinghai, diverting the Yellow River to Zizi, diverting the Yellow River to Jin, diverting the Yellow River to Jin from Wanjiazhai, diverting Luan to Tianjin, diverting Ejike, Yinerjiwu, Liaoning East-West Water Diversion, East Route of South-to-North Water Diversion, Middle Route of South-North Water Diversion, etc. There are such problems. Some even have to rely on financial subsidies and other blood transfusion m...
