中文摘要：
根据中国华南（包括扬子台地）,塔里木和华北板块疑源类资料作出奥陶纪属级疑源类多样性曲线,这一多样性曲线与地区及全球海平面变化有一定联系。中国奥陶纪疑源类多样性曲线峰值的时间与早-中奥陶世之交（阿伦尼格阶中部）,桑比阶-凯迪阶之交和凯迪阶上部（阿什极阶）等三次全球性海平面上升时间基本一致。
英文摘要：
The Chinese Ordovician acritarch diversity curve is here presented using all literature data from South China （including the Yangtze Platform）, Tarim and North China at the generic level. The diversity changes can partly be related to sea level changes, both at a regional （South Chinese sea level curve） and at a global level （global curve）. The curve for all Chinese localities indicates that peaks in diversity apparently correspond to three sea level highstands at a global level at the early-middle Ordoviciau boundary （middle ＂Arenigian＂）, at the Sandbian-Katian boundary （middle ＂Caradocian＇） and during the Upper Katian （pre-Hirnantian ＂Ashgillian＂）.
