| 摘 要： | 本文连续12个月监测了滇池草海柱状沉积物间隙水和上覆水不同形态氮磷浓度的垂向变化,揭示了不同季节间隙水与上覆水氮磷浓度差异及其形态组成贡献率,探讨了间隙水氮磷组成及氮/磷比值在湖泊富营养化及内负荷控制中的重要意义.结果表明:(1)草海间隙水NH_4~+-N浓度显著高于上覆水,而上覆水中NO_3~--N浓度显著高于间隙水,春、夏和秋季(2~11月)间隙水SRP浓度显著高于上覆水,而冬季(12月和1月)则与之恰好相反;(2)草海间隙水以NH_4~+-N和SRP贡献为主,分别占DTN和DTP的61%和78%,而上覆水则以DON和DOP贡献为主,分别占DTN和DTP的44%和81%,与春季和冬季相比,夏、秋季间隙水NH_4~+-N和SRP贡献率显著增加,而NO_3~--N、DON和DOP贡献率明显下降;(3)草海间隙水DTN/DTP、(NH_4~+-N+NO_3~--N)/SRP和DON/DOP比值均表现为春季冬季夏季秋季,而上覆水氮/磷比值则以春季较高,夏、秋和冬季相对较低.
