Therefore, some published-data from long-term field experiments were used to construct assessment model of the change in soil organic carbon density induced by conservational farming systems in paddy fields in Yangtze Delta Plain.

利用已发表的田间定位试验数据，构建不同耕作制度下长江三角洲水田耕层土壤有机碳密度的估算模型。

It is shown from the assessment results that (1) both the TN and TP fluxes discharged from the Changjiang River to the Changjiang River estuary sea area increased continuedly, the DIN concentration in the sea areas increased continuedly, and the Si concentration decreased continuedly, which resulted in the significant changes in N/P/Si ratios;(2) the chlorophyll a concentration in the sea areas increased continuedly, and the significant changes in community structure of phytoplankton occurred;(3) the species and biomass of benthos declined greatly, and the bottom oxygen-poor water area increased significantly;(4) the range and occurrence frequency of red tide events in the sea areas increased greatly, and the algal toxic infection events of mussel were frequently found in the sea areas.

结果表明，长江向长江口海域输送总氮和总磷通量持续增大，长江口及其邻近海域无机氮浓度持续增高而硅浓度持续下降，并由此导致N/P/Si与比值的显著变化；该海域叶绿素a浓度持续增大，浮游植物群落结构也发生了显著变化；该海域底栖生物种类和生物量都大大减少，底层水低氧区面积也显著扩大；该海域赤潮事件无论是规模还是频率都大大增加，藻类毒素DSP/PSP贻贝传染事件也时有发生。
