内蒙古乌梁素海 N、P 的变化趋势研究
Study on variation trend of nitrogen and phosphorus in Wuliangsuhai lake of Inner Mongolia
摘要
Abstract
In order to study the purification of reed for water nutrient in Wuliangsuhai Lake, the paper collected some samples such as water, sediment and reed in south of the lake to analyze the variation trends of TN, TP and N/P.The results showed that in the flow process of water from the central lake to the shore, TN content first increases and then decreases, TP content in water and reed keep stable, while TP content in sediment samples continued to increase.TN and TP concentrations ranged from 1.44 to 19.31 mg/L and 0.024 to 0.057 mg/L respectively while the rate of N to P is far greater than 16, which indicates that the Wuliangsuhai Lake is in the state of eutrophication of excessive nitrogen.The biomass of reed increases with the increase of nutrient content, and has certain role of absorbing for nutrient salt. Reasonable harvest of reed can promote the removal of N and P in Wuliangsuhai lake and the development of local economy.关键词
