中文摘要：The investigation of whether sediment samples contain representative grain size distribution information is important for the accurate extraction of sediment characteristics and conduct of related sedimentary record studies.This study comparatively analyzed the numerical and qualitative differences and the degree of correlation of 36 sets of the characteristic parameters of surface sediment parallel sample grain size distribution from three sampling profiles at Jinsha Bay Beach in Zhanjiang,western Guangdong.At each sampling point,five parallel subsamples were established at intervals of 0,10,20,50,and 100 cm along the coastline.The research findings indicate the following:1)relatively large differences in the mean values of the different parallel samples(0.19–0.34?),with smaller differences observed in other characteristic grain sizes(D_(10),D_(50),and D_(90));2)small differences in characteristic values among various parallel sample grain size parameters,with at least 33%of the combinations of qualitative results showing inconsistency;3)50%of the regression equations between the skewness of different parallel samples displaying no significant correlation;4)relative deviations of?47.91%to 27.63%and?49.20%to 2.08%existing between the particle size parameters of a single sample and parallel samples(with the average obtained)at intervals of 10 and 50 cm,respectively.As such,small spatial differences,even within 100 cm,can considerably affect grain size parameters.Given the uncertain reasons underlying the representativeness of the samples,which may only cover the area immediately surrounding the sampling station,researchers are advised to design parallel sample collection strategies based on the spatiotemporal distribution characteristics of the parameters of interest during sediment sample collection.This study provides a typical case of the comparative analysis of parallel sample grain size parameters,with a focus on small spatial beach sediment,which contributes to the enhanced understanding of the accuracy and reliability of sediment sample collection strategies and extraction of grain size information.

外文摘要：The investigation of whether sediment samples contain representative grain size distribution information is important for the accurate extraction of sediment characteristics and conduct of related sedimentary record studies. This study comparatively analyzed the numerical and qualitative differences and the degree of correlation of 36 sets of the characteristic parameters of surface sediment parallel sample grain size distribution from three sampling profiles at Jinsha Bay Beach in Zhanjiang, western Guangdong. At each sampling point, five parallel subsamples were established at intervals of 0, 10, 20, 50, and 100 cm along the coastline. The research findings indicate the following: 1) relatively large differences in the mean values of the different parallel samples (0.19-0.34 phi), with smaller differences observed in other characteristic grain sizes (D10, D50, and D90); 2) small differences in characteristic values among various parallel sample grain size parameters, with at least 33% of the combinations of qualitative results showing inconsistency; 3) 50% of the regression equations between the skewness of different parallel samples displaying no significant correlation; 4) relative deviations of -47.91% to 27.63% and -49.20% to 2.08% existing between the particle size parameters of a single sample and parallel samples (with the average obtained) at intervals of 10 and 50 cm, respectively. As such, small spatial differences, even within 100 cm, can considerably affect grain size parameters. Given the uncertain reasons underlying the representativeness of the samples, which may only cover the area immediately surrounding the sampling station, researchers are advised to design parallel sample collection strategies based on the spatiotemporal distribution characteristics of the parameters of interest during sediment sample collection. This study provides a typical case of the comparative analysis of parallel sample grain size parameters, with a focus on small spatial beach sediment, which contributes to the enhanced understanding of the accuracy and reliability of sediment sample collection strategies and extraction of grain size information.
