| 摘 要： | 2006年9~10月在长江采集悬浮颗粒物样品,应用改进后的SEDEX法对磷的赋存形态进行了分析.结果表明,自生磷灰石磷是长江悬浮颗粒物中磷的主要赋存形态.涪陵至万州江段,碎屑磷灰石磷的含量较高,弱吸附态磷和有机磷含量较低,磷的赋存形态主要受悬浮颗粒物含量的影响;香溪至葛洲坝下江段,弱吸附态磷和有机磷含量较高,碎屑磷灰石磷含量较低,磷的赋存形态主要受浮游植物生长及泥沙粒径的影响;城陵矶至大通江段,有机磷、碎屑磷灰石磷和铁结合态磷含量较高,弱吸附态磷含量较低,磷的赋存形态主要受泥沙粒径和洞庭湖输入的影响.长江悬浮颗粒物中生物可利用磷占颗粒态磷的45.6%,长江上游水体中生物可利用磷含量较低,下游含量较高.

| Abstract: | Samples of suspended particulate matter were collected from Yangtze River for the period September through October 2006.The phosphorus forms in the suspended particulate matter samples were extracted and examined using the improved technology from the sequential extration method(SEDEX) Ltd.The results show that the authigenic apatite is the dominant form of particulate phosphorus in the Yangtze River.However,the distribution of phosphorus speciation and the primary influential factor appear to be different ... |
