Study On Water Resources Allocation Of Xi'an City Based On "The Project Of Eight Rivers Moisten Xi'an"

The project of eight rivers moisten Xi'an(The water ecological construction program o Xi'an)is a designed to urban ecological water system planning and water engineering construction as the main content of urban water ecological restoration project.The situation of water resources,natural,Economic is collected in this thesis.Combined with The project of eight rivers moisten Xi'an,analyze the xi'an existing water resources supply and demand balance.Referencing the statement and planning of Xi'an water resources,the thesis calculated the water demand and water supply of each Xi'an department.The optimal model of the allocation of water resources was calculated and optimized using this model.The main achievements are listed as follows:(1)Analysis of all kinds of ecological water requirement calculation method are discussed under the concept of ecological water requirement.Discussed the calculation method of all kinds of ecological water requirement analysis,the thesis calculates the Xi'an river ecological water requirement and water requirement of lake basin under The project of eight rivers moisten Xi'an.(2)Based on the actuality of water resources an the water supply and use status in Xi'an,considering The project of eight rivers moisten Xi'an,the industrial,domestic,agricultural and ecological water demand are predicted,the supply and demand balance are analyzed.Proves the necessity of optimizing allocation of water resources for ecological.(3)Each lake pool water requirement of The project of eight rivers moisten Xi'an is allocated with other type of water firstly.In this thesis,The fuzzy linear program with different constraints,xi 'an water resources optimization allocation model is set up and to solve.And on the basis of this scheme ?,considering the principle of ecological water use in The project of eight rivers moisten Xi'an,excute second optimization.This model ? pay attention to groundwater protection,which has embodied the thought of sustainable development,and is beneficial to economic benefit and water supply reliability,the optimal allocation scheme provide reference and decision basis for the The project of eight rivers moisten Xi'an.
