中文摘要	为探明寒旱区草原型湖泊乌梁素海水体富营养化季节性特征,评价水体营养状态并分析富营养化季节性变化特征,同时讨论富营养化的主要影响因子,并结合多元线性回归分析法拟合各季节水体营养状态的线性模型。结果表明:春季的富营养化状态明显高于夏、秋和冬季,但湖泊营养状态级别较稳定,没有明显的水质恶化趋势。不同季节富营养化主要驱动因子各异,春季营养状态主要与SD、pH、ORP和CODcr有关,夏季营养状态主要与SD和CODcr有关,秋季营养状态主要与SD、DO、CODcr、TP和TN有关,冬季营养状态主要与水深和TN有关。建立的富营养状态多元线性回归模型模拟精度高达87%以上,模型可以很好地对不同季节湖泊营养状态进行模拟。
英文摘要	In order to probe the seasonal characteristics of eutrophication in Wuliangsu lake,a grassland - type lake in cold and arid regions,the water body in spring,summer,autumn and winter of 2014 - 2016 was sampled and analyzed. The comprehensive trophic state index method was used to evaluate the eutrophication status and analyze the seasonal variation characteristics of eutrophication. Meanwhile,the main influencing factors of eutrophication were discussed combined with multiple linear regression analysis. The analytical method was used to fit the linear model of water nutrient status in each season. The results showed that the eutrophication status in spring was significantly higher than that in summer,autumn and winter,but the eutrophication level of lakes was relatively stable,and there was no obvious deterioration trend of water quality. The main driving factors of eutrophication were different in different seasons. The nutritional status in spring was mainly related to SD,pH, ORP and COD_(Cr). The nutritional status in summer was mainly related to SD and COD_(Cr). The nutritional status in autumn was mainly related to SD,DO,CODcr,TP and TN. The nutritional status in winter was mainly related to water depth and TN. The simulation accuracy of the multivariate linear regression model of eutrophication states was over 87%. The model can simulate the eutrophication state of lakes in different seasons very well.
