Effects of long-term fertilization on particulate organic carbon and mineral organic carbon of the paddy soil;

The sources, seasonal variation and transported fluxes of the riverine particulate organic carbon of the Zengjiang River, Southern China;

The water samples of the surface layer sampled in the lower Yangtze River from June 2003 to July 2005 were used for determination of dissolved organic carbon (DOC) and particulate organic carbon (POC).

DIURNAL DYNAMICS OF DOC AND POC IN SHRIMP POND ECOSYSTEMS;

A Primary Research on the Distribution and Vertical Flux of POC and PN in East China Sea;

This paper,the discussion and analyses of the characteristics on spatio-temporal variations of particulate organic carbon and the relation between seawater physico-chemical factors and POC were made.

A typical rolling farmland in the Black Soil region of Northeast China was selected in a case study to analyze impact of soil erosion and deposition on the loss,transportation and accumulation of soil organic carbon(SOC) in topsoil by measuring particulate organic carbon(POC),composition of water stable aggregates of different sizes and contents of associated carbon in different slope positions.

Based on the upper ocean beam attenuation(660 nm) profiles obtained in the Philippine Sea in the summer of 2004,an optical statistical model for the suspended particulate organic carbon(POC) in the sea area is proposed.

Relationship between grain size of total suspended solids(TSS)and particulate organic carbon(POC)content is the base of studying POC transportation and flux in river.
