  • 摘要: 对盐龙湖水源生态净化系统预处理区、挺水植物区、沉水植物区及深度净化区沉积物中营养盐内源负荷及氮、磷的形态空间分布特征展开研究，并评价不同单元沉积物营养盐污染状况.结果表明：盐龙湖表层沉积物总氮（TN）、总磷（TP）、有机质（OM）含量范围分别为156.43—1130.00 mg·kg-1、615.23—1580.66 mg·kg-1、5.00%—49.04%.盐龙湖TP含量在预处理单元的沉积物中最高（1508.09 mg·kg-1），在挺水植物区B的沉积物中最低（932.30 mg·kg-1），而TN和OM含量都在挺水植物区A的沉积物中达到顶峰（1126.91 mg·kg-1， 48.89%），在深度净化区的沉积物中最低（272.47 mg·kg-1， 5.23%）.闭蓄态磷（Abs-P）的含量占总磷（TP）比例最多（75.3%—82.3%），易解析磷（Exch-P）占TP比例均不超过1%；顺水流方向，铁结合态磷（Fe-P）和铝结合态磷（Al-P）含量呈下降的趋势，而Exch-P和钙磷（Ca-P）呈U字型先减后增.弱酸可提取态氮（WAEF-N）占可转化态氮（TTN）比例最高（45.3%—68.94%），强氧化剂可提取态氮（SOEF-N）占TTN比例最低（10.45%—19.08%），沉积物TTN中各形态氮含量分布次序为弱酸可提取态氮（WAEF-N）>强碱可提取态氮（SAEF-N）>离子交换态氮（IEF-N）>强氧化剂可提取态氮（SOEF-N）.通过单一因子标准指数法、综合污染指数、有机氮和有机指数法进行评价，发现在预处理区和挺水植物区A营养盐污染最严重，其他处理单元也有不同程度的污染，深度净化区污染程度最低.
    Abstract: This study aimed to identify the spatial distribution of endogenous load of nutrients and distribution characteristics of nitrogen and phosphorus in the pretreatment area, emerged plant area, submerged plant area and deep purification area of Yanlong Lake ecological purification system and evaluate the pollution of nutrients in the sediments of different units. The results showed that the contents of total nitrogen (TN), total phosphorus (TP) and organic matter (OM) in the surface sediments of Yanlong Lake were 156.43-1130.00 mg·kg-1, 615.23-1580.66 mg·kg-1, 5.00%-49.04%, respectively. The upper (1508.09 mg·kg-1) and lower (932.30 mg·kg-1) range of TP content was in the sediments of the pretreatment unit and emergence plant area B, respectively. The sediments of the emergence plant area A had the upper range of TN (1126.91 mg·kg-1) and OM (48.89%), and the lower range of TN (272.47 mg·kg-1) and OM (5.23%) was in the deep purification zone sediments. Occluded phosphorus (Abs-P) accounted for 75.3%-82.3% of TP, the largest proportion. Exch-P had ≤ 1% of TP. In the direction along the flow, the contents of Iron phosphorus (Fe-P) and Aluminum phosphorus (Al-P) presented a tendency of decrease. The contents of Exch-P and Ca-P in the direction along flow at first decreased and then increased, showing a U-shaped trend. Weak acid extractable form (WAEF-N) accounted for the largest proportion of TTN (45.3%-68.94%), and Strong oxidant extractable form (SOEF-N) had 10.45%-19.08% of TTN, the lowest proportion. The morphological nitrogen contents in the sediment TTN were in the order of WAEF-N > strong alkali extractable form (SAEF-N) > ion exchange form (IEF-N) > SOEF-N. Our results from the single factor index method, comprehensive pollution index, organic nitrogen and organic index method demonstrated that the pollution in the pre-treatment zone S1 and emergent water plant zone S2 is the most serious and the deep purification zone S6 is the least polluted, along with other treatment units polluted to one degree or another.
