内蒙古乌梁素海生态恢复工程试验研究

在典型草型富营养化湖泊内蒙古乌梁素海设立试验研究基地,进行较大规模的生态恢复工程试验,研究表明实施沉水植物收割工程是草型富营养化湖泊生态恢复的重要技术措施.以机械化方式收割沉水植物能够削减湖泊内源性营养物负荷的积累和释放,减少二次污染,抑制生物填平作用,改善水体环境.有计划、合理地运用生态恢复工程,不仅可以减轻草型湖泊所面临的巨大生态压力,延缓沼泽化演化进程,而且可以在实施生态工程的同时开发利用水生植物资源,使湖泊环境与湿地综合利用得到持续发展.

Study on the Ecological Restoration Program of Wuliangsuhai Lake in NeiMongol

An experimental base was established in Wuliangsuhai Lake of NeiMongol.It is a typical plant eutrophic lake,where a series of ecological environment restoration experiments were carried out on a large scale.The results of the experiments indicate that the implementation of submerged plant harvesting is an important technical measure to restore the ecological environment for the plant eutrophic lake.To harvest submerged plants by mechanical means will be possible to cut back the accumulation and release inner nutrient loads,reduce repollution,restrict the deposition effect of living things and meliorate the environment of water body in the lake.The application of the ecological restoration engineering technology in a planned way not only lessens the burden of the lake from ecological devolution and postpones the process of marshland formation,but also exploits the aquatic plant resources and makes the wetland of the lake sustainable developed.
