长乐沿海风成沙沙色与红化作用研究

A Study of the Color and Red Coloration of Aeolian Sand in Changle Coastal Zone

根据对长乐东部沿海潮间带和陆上风成沙分布区实地取样调查,以及时颗粒表面特征的观测和实样化学分析等,查明了区内风成沙颗粒成分和形成环境对沙色的影响。分析研究了沙源与沙色变化的关系,沙色分布规律,无色颗粒红化作用的起因及红化过程。

On the basic of the field investigation on and specimen collecting in the shore and aeolian sand in Changle coastal zone, the measurements to the facial features of grains, the chemical analysis of specimens and others indoors, we can understand the effect of grain ingredients and natural environment on sand color, the relationship between sand source and color, the distributive regulation of sand color, the cause of red coloration of colorless grains and the red coloration course in this region.
