4 建設(shè)項(xiàng)目取用水合理性分析
4.1 取水合理性分析
4.1.1 產(chǎn)業(yè)政策和水資源管理要求
（1）產(chǎn)業(yè)政策
按《建設(shè)項(xiàng)目水資源論證導(dǎo)則（試行）》（SL/Z 322-2005）的要求，水利類建設(shè)項(xiàng)目應(yīng)符合國務(wù)院印發(fā)的《水利產(chǎn)業(yè)政策》（國發(fā)[1997]35號）和地方制定的水利產(chǎn)業(yè)政策實(shí)施方案。《水利產(chǎn)業(yè)政策》第四條和第七條規(guī)定：水力發(fā)電項(xiàng)目為本政策實(shí)施期內(nèi)的乙類水利建設(shè)重點(diǎn)項(xiàng)目之一

5 建設(shè)項(xiàng)目取水水源論證
5.1 依據(jù)的資料與方法
5.1.1 XX水文站基本情況
設(shè)計(jì)流域上游有位于XX流域上的XX水文站，該站地處

6 取水的影響分析
6.1 對區(qū)域水資源的影響
6.1.1 對水資源量的影響
該項(xiàng)目為壩后式且具有日調(diào)節(jié)的水電站，其取水量為流域天然來水量，壩址處多年平均流量31.5m3/s，來水量經(jīng)過水輪機(jī)組發(fā)電除冷卻系統(tǒng)帶走少量蒸發(fā)損失外，無其它水量損失。

7 退水的影響分析
7.1 退水系統(tǒng)及組成
XX水電站退水系統(tǒng)由發(fā)電引水系統(tǒng)和泄洪建筑物組成。本工程采用壓力鋼管引水，壩內(nèi)式取水口方案，
