WANG Guoping;LIU Jingshuang;TANG Jie. ADVANCE IN MARSH SEDIMENTATION AND ENVIRONMENTAL CHANGE STUDY[J]. Advances in Earth Science, 2005, 20(3): 304-311.

Marsh usually occurred at the interface of terrestrial and aquatic ecosystems, and formed by the interaction of them. The research of marsh initiated in the 1960s in our country. However, the study of marsh sedimentation and environmental changes was relatively weak, even though we have done some preliminary works on an approach to the characteristics of spore-pollen assemblage of peat in the Holocene and paleo-environmwent, and formation mechanism and deposition kinetics of peatland since 1990s. But we are lacking in systematic research on gleying marsh, especially on recent short time-scale and high-resolution sedimentation records of environmental changes. There is a certain disparity in this field compared with lake sedimentation and environmental changes. On the basis of summarizing the status quotation of related researches at home and abroad, problems in related researches and studies are analyzed and the important research fields and contents in marsh sedimentology are chosen:Establishing different model of marsh sedimentation, to support marsh definition and classification from sedimentology; Advancing theory and quantification, to analyze formation process of marsh from quality to quantity methods; Applying modern sampling system and setting up standard sedimentation profiles; Strengthening the research of gleying marsh inland and its recent process and evidence derived from sedimentation profile; Enlarging geography fields and comparing between spatial and temporal research, and enforcing regional short time-scale and high-resolution environmental change; Paying much more attention on correlations between watershed environment and information derived from marsh sedimentary records and especially on their controlling mechanism.
