摘要
本文针对济南市典型生态湿地华山洼开展生态修复研究。首先对华山洼的蓄水、调水、降雨以及面源地表径流等水体入湖污染负荷进行调查与评估,结果显示,华山洼最主要的污染源为面源污染,持续的污染负荷输入势必导致水质恶化。随后进行生态修复的可行性分析,因地制宜提出截污(微生态网膜)、基底改良、高等水生植物群落构建、大型底栖动物群落构建、鱼类群落构建以及优化调整工程等水生态修复方案,建设海绵城市。
This paper studied ecological restoration on a typical ecological wetland in Huashanwa of Jinan.First of all,this paper investigated and evaluated the input load of pollutants though impoundment,pumping water,precipitation and urban surface runoff,respectively.The results show that Huashanwa is endangering sever non-point source pollution,and will be faced of water quality deterioration.Subsequently,the feasibility analysis of ecological restoration was carried out,and the water ecological restoration schemes such as interception(micro-ecological membrane),substrate improvement,construction of higher aquatic plant communities,construction of macrobenthos community,fish community construction and optimization and adjustment engineering were proposed according to local conditions,in order to build a sponge city.
