摘要
长春南湖大型水生植物的干质量热值随着生长季的推进而升高。附生藻类的净生产力为0 30kJ (m2·d)。大型水生植物的净生产力为1 95kJ (m2·d)。浮游植物、大型水生植物和附生藻类在净初级生产力中的比例分别为93%、6%和1%。可收获的大型水生植物每年可将一定数量的磷带出湖体。
The thermal values of macrophyte in the Nanhu Lake increased with the progress of growth season.The net primary productions of periphyton and macrophyte were 0.30 kJ/(m^2·d) and (1.95 kJ/(m^2·d))respectively.The percentages of phytoplankton,macrophyte and periphyton in the total net primary production were 93%,6% and 1% respectively.As an efficient measure to control lake eutrophication,harvest of macrophyte could remove a certain amount of phosphorus out of the lake body.Ecological engineering has showed a considerable application prospect in eutrophication control.
