5) Sediment dredging
底泥疏浚
1.
Research on variety of plankton community prior and post sediment dredging in Nanhu Lake,Changchun;
底泥疏浚前后长春南湖浮游生物群落变化研究
2.
Sediment dredging can effectively lower the contents of nutrient,heavy metals and persistent organic pollutants in sediment,but resuspensiou of sedi- ment during dredging will induce the release of pollutants from sediment to the water column.
底泥疏浚的效果至今仍存在很大争议,其中之一是疏浚后所产生的环境效果有可能偏离人们的期望,疏浚能够有效的削减沉积物中营养物、重金属和持久性有机物等污染物含量,但疏浚过程中会引起污染物向水体释放,疏浚后的界面过程有可能对疏浚效果产生较大影响,底泥疏浚对水体富营养化的控制有成功的经验也有失败的教训,不同的湖泊疏浚后对营养盐释放的控制效果不同。
3.
