摘要
[目的]研究大周库湾网箱养鱼对水质的影响。[方法]以三峡库区大周库湾网箱养殖现场调查数据为基础，采用水质相对影响度分析了网箱养殖对周围水质的影响。[结果]网箱养殖对库湾积累区水体中DO、pH、NH3-N、TN、TP和Chla的影响最大。越靠近江心，水体水质呈逐渐好转趋势。[结论]该研究可为库区支流环境管理提供技术支持。
Abstract
[Objective] The aim was to study effects of cage culture in Dazhou Reservoir Bay on water quality. [Method] Based on investigation data of cage culture in Dazhou Reservoir Bay,using relative influence degree,effects of cage culture on water quality were analyzed. [Result] Cage culture had most significant influence on DO,pH,NH3 -N,TN,TP and Chla in water of accumulation area. Closer to the middle of the riv-er,water quality in the overall trend showed a gradual improvement. [Conclusion] The study can provide technical support for environment man-agement of tributary in reservoir area.
