Benthic foraminifer fauna, ams14c dating and acoustic sub - bottom profile was analyzed in the core ey02 - 2 and ey02 - 1 drilled from the muddy deposit in the middle southern yellow sea and the mid - shelf of north east china sea. considering the results of core qc2 ? dz4 and the standard oxygen isotope curves, we discussed the late - quaterenary paleo - environment evolution, benthic foraminifer fauna, paleo - climate, the climate events and water mass in postglacial period, average sedimentation rates, paleo - water depth, origin of sediments, average sea level rise rate in the shelf of south yellow sea and east china sea. at last we discussed the condition of sea level rise in the east china, green house effect and the protection of coastal zone

The ecological study of macrofauna was conducted on four typical sampling stations selected in the northern muddy bottom area of jiaozhou bay, estuary of dagu river, culturing and nearby area in hangdao in mar., jun., aug. and dec., 2002. abundance and biomass of macrofauna were investigated by quantitative study. the macrobenthic community structure and biodiversity were analyzed through multivariate statistic analysis
本研究分別在膠州灣北部軟底區、大沽河口、黃島養殖區及養殖區鄰域選取四個典型站位，於2002年3月、 6月、 8月和12月野外采樣，對大型底棲動物進行了定量研究，採用多元統計方法分析了群落結構和生物多樣性，探討了底棲生物群落與環境因子的關系；用豐度和生物量比較曲線法分析大型底棲生物群落對自然和人為擾動產生的響應。 -
The comparison curves of the abundance and biomass indicate that the macrobenthic community in the northern muddy bottom area has been disturbed moderately. there was no disturbance detected in culturing area, but the abundance of some species with small size was dominant there
豐度和生物量比較曲線（ abc曲線）表明，灣北部軟底區站位的底棲群落處于中等干擾狀態，其他海域站位的底棲群落尚未表現出受干擾的狀況。
