百花湖水体氮的空间分布研究
初步探讨了百花湖水体中氮的空间分布特征,并分析了氮及溶解氧（DO）的相关性。对8个站位的表层、4m、8m及12m水体中总氮、氨氮、硝酸盐氮、亚硝酸盐氮及溶解氧进行了测定。结果表明,百花湖水体中总氮的平均含量为1.18mg/L,氨氮的平均含量为0.144mg/L,硝酸盐氮的平均含量为0.20mg/L,亚硝酸盐氮的平均含量为0.018mg/L。百花湖入湖口附近的1号采样点总氮、氨氮和硝酸盐氮的平均浓度都较其它采样点高。分析表明百花湖中DO浓度与硝酸盐氮和亚硝酸盐氮呈负相关,相关系数分别为-0.629、-0.724。...

| Notes | 45-1157/P Vertical distribution of inorganic nitrogen in the water from the Baihua Lake and the correlations between nitrogen forms and dissolved oxygen（DO） are analyzed in this study.The concentrations of total nitrogen（TN）,ammonia nitrogen（NH4＋-N）,nitrate nitrogen（NO3——N）,nitrite nitrogen（NO2——N） and dissolved oxygen in eight water samples（surface,4 m,8 m and 12 m under the water） are determined.The results show that the total nitrogen average concentration of the water is 1.18 mg/L,with ammonia nitrogen being 0.144 mg/L,nitrate nitrogen 0.20 mg/L and nitrite nitrogen 0.018 mg/L Furthermore,the average concentrations of total nitrogen,ammonia and nitrate nitrogen are higher at the inlot point in comparison to other sampling points.In addition,the correlation analysis demonstrated that there are significant negative correlations between DO concentration and two nitrogen forms（nitrate nitrogen and nitrite nitrogen） with correlation coefficient-0.629 and-0.724.
