苍山溪流疏导引水管径

Diversion Diameter of River in Cangshan

高原明珠洱海发源于洱源县茈碧湖,源头出自罢谷山,北有弥直河注入,东南收波罗江水,西纳苍山18溪水,总径流面积2565km^(2),洱海具有供水、农灌、发电、调节气候、渔业、航运、旅游七大主要功能,保护洱海首先应治理流域源头,以改善水质为核心,疏导清水优水入湖,重点从苍山国家级自然保护区临洱海坡面进行雨污分流,实施清水入湖疏导,增加清水优水入湖量。对此以苍山面临洱海东坡的白石溪中银村箐沟为例对清水入湖引水管径及流量进行探讨。

Erhai Lake originates from Bihu Lake in Eryuan County,and originates from Bacu Mountain.It is fed by Mizhi River in the north,the Baltic River in the southeast,and the streams of Cangshan in the West,with a total runoff area of 2565 km^(2).Erhai Lake has seven major functions:water supply,agricultural irrigation,power generation,climate regulation,fishery,shipping and tourism.In order to protect Erhai Lake,we should first harness the source of the basin,focus on improving water quality,and channel clean water into the lake.Rainwater and sewage will be diverted from the slope near Erhai Lake in Cangshan National Nature Reserve,and clear water will be channeled into the lake to increase the flow of clean water and water.Taking Qinggou of Zhongyin Village as an example,this paper discusses the diameter and flow of the water diversion pipe into the lake.
