Part I: General information of the schistosomiasis in Qingpu From 1950 to 1983, many methods had been applied to the schistosomiasis field examination, such as proctoscopy, microscopy examination of stool sedimentation, hatching examination of stool sedimentation, hatching examination of stool floatation, and comprehensive diagnosis, etc.

第一部分：青浦区血吸虫病的查治概况 1950-1983年间，该区采用直肠镜检、粪便沉淀镜检、粪便沉孵三送三检、粪便孵化三送三检法和综合诊断等检查、诊断方法，共查病3，652，200多人次，累计查出15.72万病人，其中晚期血吸虫病人6014人，占病人总数的3.82%。

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 sporepollen assemblage of peat in the Holocene and paleoenvironmwent, and formation mechanism and deposition kinetics of peatland since 1990s. But we are lacking in systematic research on gleying marsh, especially on recent short timescale and highresolution sedimentation records of environmental changes. There is a certain disparity in this field compared with lake sedimentation and environmental changes.

我国沼泽研究起步于20 世纪60 年代，期间有关沼泽沉积与环境的研究相对薄弱，90 年代以来虽已在泥炭沼泽孢粉解译全新世环境变化与泥炭沉积动力学方面有初步积累，但对潜育沼泽缺乏系统研究，尤其缺乏近代短时间尺度高分辨率环境变化历史记录研究，这方面与湖泊沉积及其环境演变研究相比已形成一定的差距。
