摘　　要：为探究西北干旱半干旱湖泊水生植物氮磷积累特征,研究2017年8月至9月青格达湖不同生活型及同种生活型不同种类水生植物氮、磷含量及其积累特征,以及青格达湖水生植物氮、磷积累特征与水质因子相关性。结果表明:青格达湖水生植物氮元素富集能力远远大于磷营养盐富集能力;不同生活型水生植物氮、磷积累存在一定规律,沉水植物总氮含量极显著高于挺水植物总氮含量;沉水植物总磷含量显著高于挺水植物总磷含量;不同种类挺水植物氮磷含量不同,青格达湖4种挺水植物氮磷含量均存在极显著差异,其中总氮含量积累规律为藨草>芦苇>水蓼>达香蒲,总磷含量积累规律为藨草>达香蒲>芦苇>水蓼;青格达湖水质因子与水生植物之间存在密切关系,但不同生活型及同种生活型不同种类水生植物所受水质因子的影响存在一定的差异性。In order to explore the nitrogen and phosphorus accumulation characteristics of aquatic plants in arid and semi⁃arid lakes in northwest China,the nitrogen and phosphorus content and accumulation characteristics of aquatic plants of different life types and the same life typein Qinggeda Lake were explored and correlated with water quality factors.The results showed that the nitrogen enrichment ability of aquatic plants was much greater than that of phosphorus.There were certain rules in the nitrogen and phosphorus accumulation with different life types of aquatic plants,the total nitrogen content of submerged plants was significantly higher than that of emergent plants.The nitrogen and phosphorus contents of the four kinds of uplift plants was significantly different,with nitrogen content ranking as Scirpus vulgaris>Phragmites vulgaris>Polygonum vulgare>Typha,while phosphorus content ranking as Scirpus vulgaris>Typha>Phragmites vulgaris>Polygonum vulgare.There was an obvious correlation between water quality factors and aquatic plants,the impact was different with the aquatic plants of different life types and the same life types.
