【摘要】：水系連通是解決區(qū)域水環(huán)境問題的一個重要措施,而調(diào)水量確定是水系連通工程的關(guān)鍵問題之一。提出多功能區(qū)河道自凈需水量計算公式,并將其運用于海口市中心城區(qū)水系連通工程河道水功能區(qū)水質(zhì)所要求的最小需水量計算中,應(yīng)用MIKE11水動力水質(zhì)模型進(jìn)行模擬。結(jié)果表明,計算流量是滿足河道水功能區(qū)要求水環(huán)境質(zhì)量標(biāo)準(zhǔn)的最小自凈需水量,可作為海口市中心城區(qū)水系連通工程的調(diào)水流量。秀英溝、龍昆溝及美舍河的自凈需水量分別為2.9 m~3/s、2.3 m~3/s和3.0 m~3/s;TP為計算河道自凈需水量的控制性要素;滿足該水量條件下,秀英溝、龍昆溝和美舍河水質(zhì)可達(dá)Ⅳ類、Ⅴ類、Ⅴ類要求。
[Abstract]:Water system connectivity is an important measure to solve the problem of regional water environment, and the determination of water transfer is one of the key problems in water system connectivity engineering. This paper presents a formula for calculating self-purification water demand of multi-function river channels, and applies it to the calculation of minimum water demand required by the watercourse water function area of the connected river system in the central urban area of Haikou City. The MIKE11 hydrodynamic water quality model is used to simulate the formula. The results show that the calculated discharge is the minimum self-purification water demand to meet the water environmental quality standard in the river channel water function area and can be used as the water diversion flow of the water system connectivity project in the central urban area of Haikou City. The self-purification water demand of Xiuying ditch, Longkungou and Meishe rivers were 2.9 mNW / 3 / s-1 / s and 3.0 mN3s / s respectively as the controlling factors to calculate the self-purification water demand of the river, and the water quality of Xiuying ditch, Longkungou and Meishe rivers could reach class 鈪，
