摘要
大伙房水库上游河段农田径流中的植物营养物质排入,导致湖库藻类大量繁殖,从而产生富营养化,水生态系统遭遇了严重破坏。通过对水库健康问题分析与评价,得出了该水库是健康水平。同时根据评价结果,提出了要科学配置流域水资源,优化水库调度,最大限度地发挥水库的调蓄作用,严格控制进入库区的营养盐量,防止藻类爆发,避免水华发生等保护性措施及建议。
The plant nutrients of farmland runoff discharged from the upper reaches of Dahuofang Reservoir, it caused algal blooms of lake and reservoir, resulting in eutrophication and aquatic ecosystem suffered serious damage. Through the analysis and evaluation of reservoir health problems, the result shows that reservoir is a sub healthy level. Also according to the evaluation results,we proposed protective measures and suggestions, such as a scientific allocation of water resources in the basin, optimized reservoir scheduling to maximize the use of the reservoir storage effect, and strict control of nutrient content in the reservoir to prevent the outbreak of algae and avoid blooms occur.
