1、山東大學(xué)碩士學(xué)位論文濟(jì)南市大明湖水質(zhì)評(píng)價(jià)及水質(zhì)模擬研究姓名:徐曉馳申請(qǐng)學(xué)位級(jí)別:碩士專業(yè):水文學(xué)及水資源指導(dǎo)教師:孫秀玲20090515山東大學(xué)碩士學(xué)位論文摘要湖泊是我國(guó)重要的淡水資源之一,為人們提供生活生產(chǎn)用水,是人民生活不可缺少的寶貴資源。但是,隨著我國(guó)經(jīng)濟(jì)和社會(huì)的發(fā)展,工業(yè)廢水和生活污水排放量日益增加,大量人類活動(dòng)給諸多湖泊環(huán)境造成了不良影響。目前湖泊所面臨的環(huán)境問(wèn)題主要是富營(yíng)養(yǎng)化,城市湖泊尤其嚴(yán)重。濟(jì)南市大明湖也一直被水質(zhì)惡化所困擾,水體總氮、總磷、透明度和大腸桿菌群污染較重,水體處于富營(yíng)養(yǎng)
2、狀態(tài)。為了研究防止、抑制和凈化湖泊水污染的有效方法和措施,實(shí)現(xiàn)水資源的可持續(xù)利用和良性循環(huán),本文對(duì)湖泊現(xiàn)狀條件下以及采取各種可能措施下的水質(zhì)狀況進(jìn)行模擬研究,并對(duì)模擬結(jié)果進(jìn)行評(píng)價(jià)分析,為水質(zhì)規(guī)劃和環(huán)境質(zhì)量管理提供重要依據(jù)。本文通過(guò)對(duì)大明湖2001---2005年的水質(zhì)運(yùn)用人工神經(jīng)網(wǎng)絡(luò)模型進(jìn)行水質(zhì)評(píng)價(jià),在此基礎(chǔ)之上運(yùn)用SMS軟件進(jìn)行水質(zhì)模擬,可以直觀的看出大明湖污染物濃度分布情況,水流流動(dòng)情況。然后運(yùn)用情景分析法對(duì)大明湖進(jìn)行水質(zhì)模擬,通過(guò)對(duì)結(jié)果的比較,可以直觀的反應(yīng)各個(gè)方案的好差情況,從而對(duì)大明湖進(jìn)行
