摘  要：
为探究淤积物与水生植物间的关系,制定适当的水生植物管理政策,通过在石佛寺水库人工湿地采集对比4种不同水生植物(荷花、蒲草、芦苇、混合植物)以及主河道区域的淤积物,分析各区域内淤积物密度及TOC(有机碳)含量,研究这4种水生植物对淤积物总重量及淤积深度的影响.结果表明:目前湿地内淤积较为严重,平均淤积深度为0.824m各区域淤积物平均密度为1.106t?m-3,水生植物的种植会使附近区域内淤积物密度明显降低.湿地淤积总量约为14699978t,其中生物有机质含量占1.31%,即淤积总量中有98.69%为非生物淤积,湿地内淤积物的主要是由外源的无机物质所形成的非生物淤积构成.但水生植物的促淤效应会使淤积物变得疏松,从而增加淤积物的深度.因水生植物的种植,湿地内淤积物深度增加0.261m,占湿地内平均淤积深度的31.7%.其中荷花区域内淤积物中TOC含量最高,促淤效应最为明显,使淤积深度增加约0.101m;芦苇与蒲草对淤积深度的影响较为接近,分别会使淤积深度增加0.067和0.063m;混合植物区域(包括沉水植物、根生浮叶植物和自由漂浮植物)内淤积物中TOC含量最少,促淤效应最差,但仍可以使湿地平均淤积深度增加0.030m.水生植物对于淤积深度影响的主要原因是死亡腐解后对淤积产生的疏松效应,应及时对植株残体收获利用.

摘  要：
In order to explore the relationship between silt and aquatic plants, an appropriate aquatic plant management policy was designated to collect and compare four different aquatic plants(water lily, bulrush, reed, mixed plant) and sediments in the main river channel in the constructed wetland of Shifosi Reservoir. The sediment density and TOC(organic carbon) content in each area were analyzed to study the effects of these four aquatic plants on the total weight and sedimentation depth of the sediment. The results show that the current siltation in the wetland is more serious, and the average sedimentation depth is0.824 m. The average density of silt in each area is 1.106 t·m-3. The planting of aquatic plants will significantly reduce the density of silt in the nearby area. The total amount of wetland siltation is about 14699978 t, of which the bio-organic matter content is 1.31%, that is, 98.69% of the total sedimentation amount is abiotic sedimentation. The sediment in the wetland is mainly composed of non-biofouling formed by exogenous inorganic substances. However, the siltation effect of aquatic plants can cause the sludge to become loose, thereby increasing the depth of the sludge. Due to the planting of aquatic plants, the depth of sediment in the wetland increased by 0.261 m, accounting for 31.7% of the average sedimentation depth in the wetland. Among them, the TOC content in the sediment in the lotus region is the highest, the sedimentation effect is the most obvious, and the sedimentation depth is increased by about 0.101 m. The influence of reed and pupa on the sedimentation depth is similar, which will increase the sedimentation depth by 0.067 and 0.063 m respectively, including submerged plants, root-floating plants and free-floating plants. The TOC content in the sediments is the least, and the sedimentation effect is the worst, but the average sedimentation depth of the wetlands can be increased by 0.030 m. The main reason for the influence of aquatic plants on the sedimentation depth is the loosening effect on sedimentation after death and decomposing, and the plant residues should be harvested and utilized in time.
