【摘要】：本文以典型引黃灌區(qū)——大功引黃灌區(qū)為例,對改擴(kuò)建后灌區(qū)內(nèi)的可利用水資源進(jìn)行可持續(xù)、協(xié)調(diào)優(yōu)化配置,以期獲得灌區(qū)綜合經(jīng)濟(jì)效益、單位種植面積糧食產(chǎn)量及生態(tài)供水保證率三者的協(xié)調(diào)發(fā)展指數(shù)最大。研究首先介紹了大功引黃灌區(qū)基本情況,并對改擴(kuò)建大功引黃灌區(qū)進(jìn)行了必要性和可行性分析;接下來進(jìn)行灌區(qū)的農(nóng)業(yè)灌溉需水分析,以及近遠(yuǎn)期規(guī)劃年灌區(qū)的生活、農(nóng)業(yè)、工業(yè)和生態(tài)需水量的預(yù)測,進(jìn)而得出灌區(qū)需水總量;然后計(jì)算大功引黃灌區(qū)內(nèi)的灌溉水資源可利用量,包括灌區(qū)有效降雨量、地下水可開采量和許可引黃水量,加和得到不同規(guī)劃年灌區(qū)的可供水總量;最后以整個灌區(qū)水資源綜合經(jīng)濟(jì)效益、單位種植面積糧食產(chǎn)量和生態(tài)環(huán)境供水保證率三者發(fā)展的協(xié)調(diào)指數(shù)為目標(biāo)函數(shù),同時兼顧這3個指標(biāo)盡量最大化,確定約束條件,建立基于可持續(xù)的灌區(qū)多目標(biāo)協(xié)調(diào)優(yōu)化配置模型。本文運(yùn)用的主要研究方法有模糊數(shù)學(xué)隸屬度、凈效益系數(shù)法、層次分析法、熵值法以及模糊多目標(biāo)綜合效益系數(shù)法。結(jié)果顯示,不同規(guī)劃年灌區(qū)協(xié)調(diào)發(fā)展指數(shù)分別為2020年μ=0.927,2025年μ=0.924。同時,水資源優(yōu)化配置結(jié)果表明:灌區(qū)2025年工業(yè)缺水率和農(nóng)業(yè)缺水率均小于2020年,尤其是農(nóng)業(yè)缺水率從2020年的3.2%下降到2025年的0.3%。而且協(xié)調(diào)優(yōu)化配置后灌區(qū)的社會、經(jīng)濟(jì)、生態(tài)環(huán)境均處于高度協(xié)調(diào)發(fā)展?fàn)顟B(tài),說明該方法用于優(yōu)化水資源的配置是可持續(xù)發(fā)展的,具有一定的優(yōu)勢。
[Abstract]:Taking the typical irrigated area of Yellow River-Dayong Yellow River Irrigation District as an example, this paper makes a sustainable and coordinated and optimized allocation of the available water resources in the irrigated area after the reconstruction and extension, in order to obtain the comprehensive economic benefit of the irrigation district.The coordinated development index of grain yield and ecological water supply guarantee rate per unit planting area is the largest.At first, the paper introduces the basic situation of Dayong Yellow River Irrigation District, and analyzes the necessity and feasibility of rebuilding and extending the Irrigation District, and then analyses the water demand for agricultural irrigation in irrigation area, as well as the life and agriculture of irrigation district in the near and long term planning year.Forecast of industrial and ecological water demand, and then get the total water demand of irrigation area; then calculate the available amount of irrigation water resources, including effective rainfall, groundwater exploitation amount and allowable amount of water diversion from the Yellow River.Add sum to get the total amount of water supply of irrigation district in different planning years, finally take the coordination index of the development of water resources comprehensive economic benefit, grain yield per unit planting area and the guarantee rate of ecological environment water supply as the objective function.At the same time, the three indexes are maximized, the constraint conditions are determined, and the multi-objective optimal allocation model of irrigation district based on sustainability is established.The main research methods used in this paper include membership degree of fuzzy mathematics, net benefit coefficient method, analytic hierarchy process, entropy method and fuzzy multi-objective comprehensive benefit coefficient method.The results showed that the coordinated development index of irrigation districts in different planning years was 0.927 in 2020 and 0.924 in 2025.At the same time, the optimal allocation of water resources shows that the water shortage rate of industry and agriculture in 2025 is lower than that in 2020, especially the rate of water shortage in agriculture decreases from 3.2% in 2020 to 0.3% in 2025.Moreover, the society, economy and ecological environment of irrigation district after coordinated and optimized allocation are in a highly coordinated development state, which indicates that this method is sustainable and has certain advantages in optimizing the allocation of water resources.
