【摘要】：岳城水庫(kù)位于河北省磁縣和河南省安陽(yáng)縣交界處，是海河南系漳河上的大型控制性水利工程。近年來(lái)隨著徑流的減少和上游用水的增加，岳城水庫(kù)的入庫(kù)水量逐年遞減，與此同時(shí)，隨著流域沿途工農(nóng)業(yè)的發(fā)展，排入漳河的污染總量逐年增加，再加之農(nóng)業(yè)化肥等的污染，地表徑流嚴(yán)重，使得河流水環(huán)境日趨惡化。岳城水庫(kù)除了承擔(dān)重大的防洪減災(zāi)功能以外，還擔(dān)負(fù)了城市供水、農(nóng)田灌溉等多項(xiàng)任務(wù)。為了保障邯鄲周邊區(qū)域的供水安全，保證岳城水庫(kù)水源地的可持續(xù)發(fā)展，對(duì)岳城水庫(kù)水源地的水污染控制與水環(huán)境安全進(jìn)行研究是很有必要的。 水源地脆弱性是度量水資源安全的重要標(biāo)準(zhǔn)，對(duì)其研究受到國(guó)內(nèi)外學(xué)者們的普遍關(guān)注，水源地脆弱性研究不僅可以預(yù)測(cè)未來(lái)的水資源安全變化趨勢(shì)，還可探求影響水資源安全的關(guān)鍵性要素，故水源地脆弱性研究具有非常重要的意義。 本文對(duì)岳城水庫(kù)水源地的脆弱性進(jìn)行了研究，搜集岳城水庫(kù)的數(shù)據(jù)資料，了解岳城水庫(kù)水資源的現(xiàn)狀，運(yùn)用層次分析(AHP)法，選擇年平均降雨量、年平均徑流量、干旱指數(shù)、水量利用率、水利工程調(diào)蓄能力、水工建筑物安全、人口密度、人均水資源量、人均產(chǎn)值、水質(zhì)類(lèi)別、水環(huán)境自?xún)裟芰�、水體污染物質(zhì)本底值、污水處理回用率、污染強(qiáng)度、應(yīng)急能力、COD的總量、單位農(nóng)田面積化肥施用量、人均日常生活污水排放量18個(gè)指標(biāo)構(gòu)建岳城水庫(kù)水源地脆弱性評(píng)價(jià)系統(tǒng)，，通過(guò)對(duì)水質(zhì)脆弱性和水量脆弱性?xún)煞矫娣治隽俗匀淮嗳跣�、人為脆弱性和承載脆弱性敏感指標(biāo)，利用MATLAB編程，計(jì)算各個(gè)指標(biāo)的權(quán)重量。 研究成果表明，水量脆弱性對(duì)岳城水庫(kù)水源地脆弱性影響較大，從脆弱性形成因素來(lái)看，影響岳城水庫(kù)水源地脆弱性由大到小排列為：自然脆弱性、人為脆弱性、承載脆弱性。在綜合評(píng)價(jià)體系18個(gè)指標(biāo)中，權(quán)重值占據(jù)前五名的是干旱指數(shù)、水工建筑物安全、污染強(qiáng)度、年平均降雨量、COD的總量。與實(shí)際情況基本吻合。因此針對(duì)這些因素采取必要措施，有效控制這些因素對(duì)水源地脆弱性的影響，以達(dá)到保證岳城水庫(kù)水資源安全的可持續(xù)發(fā)展的目標(biāo)。
[Abstract]:Yuecheng Reservoir is located at the junction of Cixian County in Hebei Province and Anyang County in Henan Province. It is a large controlled water conservancy project on the Zhanghe River of Haihe River system. In recent years, with the decrease of runoff and the increase of upstream water, the amount of water entering Yuecheng Reservoir decreases year by year. At the same time, with the development of industry and agriculture along the river basin, the total amount of pollution discharged into the Zhanghe River increases year by year, together with the pollution of agricultural fertilizer and so on. The surface runoff is serious, which makes the river water environment deteriorate day by day. Yuecheng Reservoir not only undertakes the important function of flood control and disaster reduction, but also undertakes many tasks, such as urban water supply, farmland irrigation and so on. In order to ensure the safety of water supply in the surrounding area of Handan and the sustainable development of the water source of Yuecheng Reservoir, it is necessary to study the water pollution control and water environment safety in the source area of Yuecheng Reservoir. Water source vulnerability is an important standard to measure water resources security. The research on water source vulnerability has received widespread attention from scholars at home and abroad. The study of water source vulnerability can not only predict the future trend of water resources security change. The key factors affecting water resources security can also be explored, so the study of water source vulnerability is of great significance. In this paper, the vulnerability of Yuecheng reservoir water source is studied, the data of Yuecheng reservoir is collected, the present situation of water resources in Yuecheng reservoir is understood, and the average annual rainfall, average runoff and drought index are selected by using the analytic hierarchy process (AHP) method. Water use efficiency, water conservancy project storage capacity, hydraulic structure safety, population density, per capita water resource volume, per capita output value, water quality category, water environment self-purification capacity, background value of water pollution substance, sewage treatment reuse rate, pollution intensity, The total amount of COD, the amount of chemical fertilizer per unit farmland area, the discharge of daily domestic sewage per capita, 18 indexes of emergency response capacity, and the vulnerability evaluation system of Yuecheng Reservoir water source area were constructed. Based on the analysis of the vulnerability of water quality and quantity, the sensitive indexes of natural vulnerability, artificial vulnerability and carrying vulnerability were analyzed. The weights of each index were calculated by MATLAB programming. The results show that the water vulnerability has a great impact on the water source vulnerability of Yuecheng reservoir. From the factors of vulnerability formation, the vulnerability of water source of Yuecheng reservoir is arranged from large to small: natural vulnerability, artificial vulnerability, and carrying vulnerability. Among the 18 indexes in the comprehensive evaluation system, the top five weighted values are the total amount of drought index, hydraulic structure safety, pollution intensity, annual average rainfall and COD. Basically consistent with the actual situation. Therefore, the necessary measures should be taken to effectively control the vulnerability of these factors to ensure the sustainable development of water resources in Yuecheng Reservoir.
