威海市崮山水库水质分析及富营养化评价
Water Quality Analysis and Eutrophication Assessment for Gushan Reservoir
摘要
Abstract
Water quality situation between 2013 and 2014 was analyzed based on Gushan reservoir,seven indexes which are T、pH、DO、COD、TN、TP and Chla were researched to find theirs changing regular ities on different times and seasons.The results show that T、pH、COD、TP and Chla levels were higher during summer and autumn,the content of DO in 2014 was increased compared with the year in 2013,meanwhile,the content of DO in summer and autumn was lower than the season in spring and winter,this also show that the more frequent biological activity during the summer and autumn.The changes in annual variation range of total nitrogen content was larger,Nitrate nitrogen and total nitrogen content were positively correlated.The ratio of TN and TP is 77 which means the reservoir belongs to phosphorus restricted type.Most of indexes were conformed to the standard of the water source for drinking and living in China except the level of TN in exceed the class V of Environmental Quality Standards for Surface Water.Meanwhile the indexes which are Chla、TP、TN、COD and SD were selected as studying targets to evaluate eutrophication in Gushan reservoir by method of Comprehensive evaluation method.The Eutrophication index of Gushan mountain in 2013 and 2014 were 52 and 49,The result shows that the quality of water in Gushan reservoir was in state of eutrophic in 2013 and then turns to mesotrophication in 2014 thanks to the ecological method that by fishing farm to control and prevent eutrophication in Gushan reservoir,Purification of water quality by using the cooperative effects and downstream effects of fish population density and different species groups,and this ecological method produced positive effect and effective progress and which provided scientific basis and practical experience to take further steps to control and prevent eutrophication of water bodies.关键词
