长距离大流量输水管涵贝类防除研

淡水贝类在河道、沟渠中的生长非常普遍，这些贝类通常在输水管线中生长、死亡，引起管道堵塞，水流不畅等诸多不良后果，由此对南方地区长距离大流量大断面输水管涵内生长的贝类种类及危害性等进行初步调查与研究，并提出初步的防除技术思路，对类似工程有一定的参考价值。

Preliminary Investigation and Research on the Shellfishes Growth in the Water Conveyance Pipes and Culverts of Long Distance and Large Discharge

It is very common for the shellfishes to grow in the rivers and ditches. But the shellfishes will grow and die in the water conveyance pipes and culverts to clog the pipe and block water flow. The species and the harmfulness of the shellfishes growing in the water conveyance pipes and culverts of long distance and large discharge in the south of China are investigated and studied preliminarily, and the prevention measures are also proposed to provide references for the similar projects.
