The results show that: (a) sediment is coarser in the submerged area than on the tidal flats, in the river mouth than out of the mouth,upstream than downstream, in deep channel than on shallow shoal. (b) for an individual sample, Mz(φ) is usually bigger than φ50, especially for silty sediment, and the difference can reach to 1. 44.

The mean depth of the soft sediment was 0.96 m, the hardness was less than 5 kgf/cm2, and the total amount of the soft sediment was about 149 million ton(in dry weight).In the silty sediment, the content of total nitrogen(TN) varied from 0.009% to 0.801%, and the con...             为揭示浅水湖泊沉积物中氮的积累及其与水生植物间的关系，１９９３年１１月在东太湖４２个样点上采集了沉积物柱状样品并进行了分析。东太湖硬度小于５ｋｇｆ／ｃｍ２的松软淤积层平均厚度０．９６ｍ，全湖淤积量１４９×１０６ｔ。粉沙质淤积物中总氮（ＴＮ）含量０．００９％～０．８０１％，总有机碳（ＴＯＣ）含量０．０１％～１７．３６％，变幅极为悬殊。总氮含量与总有机碳含量间呈密切的线性正相关ＴＮ（％）＝０．０２５１ＴＯＣ（％）＋０．００６３，表层沉积物中总氮和总有机碳含量都与水生植物的现存量有较为显著的正相关。这说明，氮和有机碳主要经过水生植物的生物沉积途径进入沉积物，水生植物有将湖水中的氮传输到底泥中，使其进入地球化学循环的功能，这对于降低湖水中的氮含量、防止富营养化有积极的意义 文摘来源   << 更多相关文摘         相关查询: silty sediment carbon sediment sediment property seafloor sediment surface sediment sediment exchange modern sediment sediment quality sediment depositing sediment change sediment tester  对查询结果不满意
