A three-year successive field investigation and laboratory analysis were conducted for factors affecting bioavailability of heavy metal (Cu, Zn, Pb and Cd ) in rhizosphere of Scirpus mariqueter.

The variation of organic carbon content in Chongming east tidal flat sediments during Scirpus mariqueter growing stage;

Carbon Storage and Fixation Function of Scirpus mariqueter in Changjiang River Estuary:A Case Study of Chongming Dongtan Wetland;

Variation Characteristics of the Macrobenthic Fauna Community in the Scirpus mariqueter Zone of the Yangtze Estuary During the Growing Seasons;

Study on Putrefaction and Decomposition Process of Scirpus triqueter on the Changjiang Estuary Tidal Flat;

Samples from 18 sediment profiles (0 to 60 cm) under 3 dominated plants (Phragmites australis, Cyperus malacceusis and Scirpus triqueter) in 2 different districts far and near a tide ditch in the middle of the Shanyutan wetland were collected.

The Effect of Miroorganism on Imperata cylindrica and Scrirpus triqueter Taking in Heavy Metal;

[Method] With analytically pure ammonia bicarbonate as restraining reagent,Imperata cylindrical and Scrirpus triqueter as tested materials,the regulated pot culture experiment was performed and their contents of heavy metals were determined after 3 months.

Study on the Bract Abaxial Epidermis of the Genus Scirpus from Shandong Province;

Field experiments were conducted, using "Fixed Interval technique for sampling seedlings", to determine the rules of asexual reproduction of Scirpus planiculmis population.

With theoretical and method ecological approach of numerical taxonomy,by selecting 8 rela- tively stable numerical characters in asexual propagation of Scirpus planiculmis in Songliao ecolog- ical area we have carried out the maximum synchronous branch classification for the investigation of the regularity in asexual propagation.
