摘 要

平潭及閩江口引水工程（福州段）是北水南調(diào)平潭及閩江口水資源配置的重要組成部分，工程從大樟溪莒口水閘上游取水，并從閩江干流竹岐取水口引水補充，引水往平潭、福清、長樂、福州南港片等地，流域主要涉及閩江、大樟溪、龍江以及平潭島等。根據(jù)《福建省北水南調(diào)平潭及閩江口水資源配置工程規(guī)劃報告》（下簡稱《報告》）提出了“一庫一閘三線” 工程規(guī)劃布局，即龍湘水庫、大樟溪莒口攔河閘和閩江竹岐～大樟溪引水線路、大樟溪～福清、平潭輸水線路、大樟溪～福州、長樂輸水線路。

本論文主要研究大樟溪～福清、平潭輸水線路對沿線河流、湖庫的水質(zhì)及富營養(yǎng)化影響。一方面通過河流二維穩(wěn)態(tài)岸邊排放公式研究調(diào)水對大樟溪水質(zhì)的影響，結(jié)果證明調(diào)水前后大樟溪水質(zhì)均滿足地表水Ⅱ類水質(zhì)標(biāo)準，影響甚微；另一方面，采用湖庫零維模型研究調(diào)水對莒口閘、東張水庫、三十六腳湖水庫的水質(zhì)及富營養(yǎng)化影響，得出各水庫水質(zhì)都達到Ⅲ類標(biāo)準，但在每年的6~9月可能出現(xiàn)輕度富營養(yǎng)化現(xiàn)象。通過本次研究，希望為相關(guān)部門及決策者提供參考依據(jù)，也為后來的研究者提供一定的思路。

Abstract

Pingtan and Minjiang Estuary Water Diversion Project (Fuzhou) is an important part of the north to south watertransfer project of Pingtan and Minjiang River estuary water resources allocation.The project gets water from Dazhang brook Jukou sluice upwater and Minjiang River Zhuqi offers water supplement，diversion to Pingtan， Fuqing，Changle，F(xiàn)uzhou，south of Fugang etc. Main basin involves Minjiang River， Dazhang brookLongjiang and Pingtan Island. According to the Fujian Province of North to South watertransfer Pingtan and Minjiang Estuary resources allocation project planning report，" a sluice and three line "project layout is proposed，namely Longxiang reservoir，Dazhang brook Jukou water gate and Minjiang Zhuqi to Dazhang brook water diversion line，Dazhang brook to Fuqing and Pingtan water conveyance line，Dazhang to Fuzhou，Changle water lines.

This report mainly studies the impact of Dazhang to Fuqing and Pingtan water conveyance line on the river and lakes .On the one hand，I choose river two-dimensional steady-state formula discharging the water diversion project’s influent of  Dazhang river water quality. The results show that Dazhang Creek water quality after the water diversion meets surface water class II water quality standard， have little effect.On the other hand，I use the lake and reservoir zero dimensional model studying the project’s effect on Jukou water gate，Dongzhang Reservoir， Sanshiliujiao lake reservoir water quality and eutrophication，it is concluded that the water quality of the reservoir reaches the third class standard，but in June to September each year may appear mild eutrophication phenomenon. Through this study，I hope to provide reference for relevant departments and decision makers and provide some ideas for later researchers.
