通过对设在南湖的围隔实施水生态修复,试验围隔内的浮游植物的种类由试验前的6个门22种,绿藻门占优势;试验后蓝藻门占优势,种类减少至5个门12种。藻类密度由2.16×107个/L 下降至0.0223×107个/L,下降了96.86倍。透明度从0.3m上升到对于1.8m。表明水生态修复技术对水体富营养化具有很好的改善作用,有很好的应用前景。
通過對設在南湖的圍隔實施水生態脩複,試驗圍隔內的浮遊植物的種類由試驗前的6箇門22種,綠藻門佔優勢;試驗後藍藻門佔優勢,種類減少至5箇門12種。藻類密度由2.16×107箇/L 下降至0.0223×107箇/L,下降瞭96.86倍。透明度從0.3m上升到對于1.8m。錶明水生態脩複技術對水體富營養化具有很好的改善作用,有很好的應用前景。

By barricading the implementation of the water ecological restoration in south lake, test barricading the phytoplankton species by test before six 22 kinds of door, chlorophyta dominant;After test, advantage of cyanophyta species reduced to five gate 12. Algae density dropped to 2.16×107个/L from0.0223×107个/L, dropped by 96.86 times. Transparency, up from 0.3 m to 1.8 m Show that water ecological restoration technology of eutrophication of water body has the very good effect, has a good application prospect.
