鲁班水库水体营养状态

四川三台鲁班水库属于大型湖库,多年来除具有特色景观作为旅游景点外,主要用于发展水产养殖业。随着时间的延续,养殖规模的不断扩大,湖库的自净能力越来越差,使有机物污染不断加重,水质越来越差,出现富营养化现象,对水环境造成了不利影响。近年来,为了改变湖库水环境质量,调整转化湖库功能,恢复水环境质量,加强了对其水质的监测,其中的营养状态指标是湖库水环境质量的主要评价指标。评价结果,除秋季和冬季个别月份外,其余各月均有测点达到轻度富营养化及中度富营养化。

The Nutritional Status of Water in Luban Reservoir

The Luban reservoir is located in Santai County of Sichuan province, which belongs to the large-scale lakes and reservoirs. It has been used as a scenic spot with characteristic landscape as well as a base to develop aquaculture for many years. With the expanding of aquaculture scale, the self-purification capacity of the reservoir was getting worse and worse. The organic pollutions aggravated unceasingly and the water quality was gradually getting worse resulting in eutrophication, which was harmful to the water environment. In recent years, in order to alleviate the water quality in Luban reservoir, adjust its function and restore the water quality, the monitoring of water quality has been strengthened. Eutrophication is a main evaluation index of water quality for lakes and reservoirs. Evaluation results showed that except for some months in fall and winter, in the months else there are monitoring points where the water quality exist light or medium eutrophication.
