金哨水利枢纽工程坝址在恒仁县沙尖子镇上金坑村上游约1km处,坝址左岸地属恒仁县,右岸地属宽甸县,电站厂房位于宽甸县下露河乡连江村境内。
枢纽工程有拦河坝、引水系统、电站厂房三部分组成。水库总库容0.98亿m3,调节库容600万m3,电站装设2台单机容量42MW的轴流转浆式水轮发电机组,总装机容量84MW,年发电量2.31亿kW/h。坝址以上控制流域面积14861km2、水库正常蓄水位139.4m,相应库容4780万m3。校核洪水位146.08m,相应库容9800万m3,集防洪、发电、灌溉、水产养殖等多功能于一体,2000年主体工程开工建设,2001年4月厂房及引水系统工程正式开工建设,2003年12月竣工投产发电。

工程建设对下游农业生产及生活用水的影响有哪些主要应调查的内容是什么

答案

参考答案:大坝建设往往造成坝下脱水,连正常的生态用水都无法保障,对下游的农业生产及生活用水带来严重的影响。因此,水利水电工程必须关注下游脱水和生态下泄流量的保障措施。

Different types of maps have different uses.
Tourist maps, for example, have signs to show places of interest in an area. When tourists read these maps, it is easy for them to find where to go and what to see in a place and it is easy for them to go and find their ways to these places. 

Road maps show large areas so that people can plan long journeys. Different types of roads are given different numbers. For example, if you want to go to Wood Green, you just follow No. 621 Road and keep looking at the road signs.

Distribution maps (分布图) use colors or signs to show facts about an area. For example, where different languages are spoken, how many people live in an area, how cold and hot some places are, or whether a place is short of water.

Some maps, such as railway maps, use straightlines to show everything. This is easy for people to read. Trains are fast. People don’t have to think about small places they go past. They just need to know the two ends of their trips.
