太湖康山湾示范区水生植物对水体氮、磷控制的适用性分析
Applicability analysis of aquatic macrophytes on controlling nitrogen and phosphorus from water in the Kangshan Bay demonstration area of Lake Taihu
摘要
Abstract
In order to restore the aquatic vegetation and improve local water quality, reconstruction of two ecological types of aquatic plants were carried out in two large enclosures in the Kangshan Bay demonstration area of Lake Taihu. By annual investigation, results showed that floating-leaved aquatic plants such as Limnanthemun nymphoides and Trapa bicomi, and submerged plant such as Potamogeton macckianus grew better than other plants under controlled conditions. Their coverage was quite high during the growing season. Results also showed that, controlling wind-driven wave disturbance and improving water transparency were the prerequisite for aquatic vegetation restoration; there was no difference about N and P contents between submerged macrophyte and floating-leaved aquatic plants, but floating-leaved aquatic plants performed better than submerged macrophyte in removing water N and P content. Concerning the economic and environmental benefit, aquatic plants including L. nymphoides , T. bicomi and P. macckianus with powerful anti-wave ability could be selected as the pioneering species to rebuild the aquatic vegetation in the open area of Lake Taihu. This research provided theoretical basis for ecological restoration in the open littoral area of Lake Taihu.关键词
