根据1975年及2003~2004年夏季在珠江口水域的表层粒度资料,研究了珠江口区域表层沉积物的分布特征,发现其平均粒径、分选性与偏度整体分布趋势相同,在北部口门存在着区域差异。结合历史文献资料对过去30年珠江口的沉积环境变化进行了探讨,结果表明珠江口表层粒度特征分布主要受水动力环境控制,区域的分布差异与人类活动的影响关系密切。该研究可以为海岸带综合管理提供科学依据。
根據1975年及2003~2004年夏季在珠江口水域的錶層粒度資料,研究瞭珠江口區域錶層沉積物的分佈特徵,髮現其平均粒徑、分選性與偏度整體分佈趨勢相同,在北部口門存在著區域差異。結閤歷史文獻資料對過去30年珠江口的沉積環境變化進行瞭探討,結果錶明珠江口錶層粒度特徵分佈主要受水動力環境控製,區域的分佈差異與人類活動的影響關繫密切。該研究可以為海岸帶綜閤管理提供科學依據。

Based on the surface grain size data which collected in the summer of 1975 and 2003~2004 in the Zhu-jiang River Estuary, the characteristics of surface sediment grain size have been analyzed. The mean grain size, sorting and skewness show a general pattern in the last 30 years, while spatial variation exists near the northern river outlet. Sedimentary environment change in the last 3 decades has been discussed based on the hydrological survey which was done in the summer of 1975 compared with historical data, the surface grain size distribution pattern is mainly controlled by the hydrodynamic environment, partial variation may be due to influence of human activities. The outcome of the research provides a sound support for integrated coastal zone management.
