摘要
为研究红树林对滩涂养殖水体的净化效应,选择四种红树植物构建三套滩涂红树林种植—养殖耦合系统,引入四类或劣于四类的涨潮海水作为各系统养殖用水。自耦合系统运行3个月起对水质进行月度监测,结果表明,三套系统中DO浓度达到国家海水水质一～二类标准,COD显著降低。其中木榄—红海榄原位水系统对引入的受污染严重的养殖水体净化效果较显著,具有推广价值。
In order to study the effect of mangrove planting on water quality＇s improvement in the estuary intertidal fishponds,4 mangrove plants were chosen to construct 3 sets of planting-aquiculture coupling systems.Seawater,at the high flood tide,was imported as the breeding water of the three systems after the coupling system had been constructed.The monthly monitoring results of water quality showed that DO concentration had achieved primary to secondary classification of national seawater quality standard,while the value of COD had obviously decreased.It was suggested that B,gymnorrhiza-R.stylosa in situ water treatment system,which could promote purification effect of serious polluted breeding water,was worthy of spreading in areas.
