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

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.

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.

The enclosed chamber technique was used to measure the methane flux from Scirpus triqueter wetland during 2 stages of tidal process(before flood and after ebb)in the Shanyutan wetland in 2007(lunar January to December,except February and April).
