东平湖流域人工湿地水生植物优化配置技术探讨

Discussion on Optimal Allocation of Aquatic Plants in Constructed Wetland in Dongping Lake Basin

本文以东平湖流域人工湿地为依托,在查询相关资料、借鉴北方湿地成功经验的基础上,选择种植8种水生植物。通过研究8种水生植物的生长周期、生长态势及不同生长阶段对水质化学需氧量(COD)、氨氮、总磷、总氮的去除效率,筛选既适合东平湖流域气候环境特点和水质特性,又具有较强水质净化能力的优势植物,为东平湖流域人工湿地建设水生植物的选择提供翔实可靠的数据资料,填补东平湖和南四湖流域在该领域的空白,并对东平湖流域水生植物优化配置方案的制定进行探讨。

Based on the artificial wetland in the Dongping Lake Basin,after inquiring about the information and learning from the successful experience of the northern wetland,this paper chose to plant 8 kinds of aquatic plants.By studying the growth cycle,growth trend and removal efficiency of water quality COD,ammonia nitrogen,total phosphorus and total nitrogen at different growth stages of 8 aquatic plants,we screened out the dominant plants that are not only suitable for the climatic and environmental characteristics and water quality characteristics of the Dongping Lake Basin,but also have a strong water purification ability.This paper provided detailed and reliable data for the selection of aquatic plants for the construction of artificial wetlands in the Dongping Lake Basin,filled the gap of Dongping Lake and Nansi Lake Basin in this field,then the formulation of the optimal allocation scheme of aquatic plants in the Dongping Lake Basin was discussed.
