Study On The Optimization Of Water Resources Of Wei-Nan City

This paper mainly researches the optimization and attempering of city water resources supply,according to the concrete situations of Wei Nan city .Its aim is to enhance the optimization and attempering of city water resources,improve the using rate to water resources,offer the decision-making basis to the construction and managing layout of water conservancy engineering .Firstly, based on the supply and demand situations in detail of Wei Nan city, make a science forecast to the water supply of different level year and water using situation. Including the calculation to three kinds of levels, the water resources available in three kinds of year type, the gross water using quantity, the water available every month, water resources requirement every month .on the basis of this, make a analysis to the balance between the supply and requirement of water quantity in the design level year .in the course of the analysis to groundwater in Wei Nan city, make a dynamic prediction to groundwater level introducing artificial neural network model ,and make a example calculation adopting BP learning arithmetic .This paper starts with the analysis to the relations between input and output for the inhomogeneous water conservancy engineering. Through the analysis calculation to the investment and the benefit of water conservancy engineering, the reasonable evaluation to theengineering built, the contrast analysis to economic benefit, at last put forward optimum project type and construction format. And develop the evaluation software about the investment and benefit. This software offers a set of standardization calculation method and program for the water conservancy engineering decision-making and scheme prior choice, thus can enhance the management level of water conservancy engineering.Lastly according to systems engineering principle, adopting dynamic planning method, make the optimization and attempering to the city water resources supply. Bring forward all-around measure to the water resources using in reason and the countermeasure to solve the shortage of water resources in the future. Develop the numeration software about water resources optimization and attempering .the programmer has friendly graphical interfaces. With enormous calculation function and database managing function. Can use for reference for the optimization and attempering to the similar medium-sized and pint -sized city water resources supply.
