| 摘 要： | 分布在孙东半岛南端滨海地区的黄民庙岛群岛、胶辽半岛黄土一起构成了我国大陆黄土分布的最东界。通过对滨海马兰黄土粒度分布的因子对应分析、拟合度计算，结合滨海黄土的孢粉分析资料，初步认为：滨海黄土是风成的，是来自西北内陆的粉砂与冰期低海面海底砂混合堆积的产物，对应的样品因子载荷值及拟合度值计算表明，粒度分布中＞4φ粒级的细粒部分主要来自西北内陆，＜4φ粒级源于渤海湾西部。

| Abstract: | The seashore loess transported and deposited by wind along south Liaoning area was derived from Bohai seabed by northwest wind in a short distance and northwest China. Factor analysis and goodness of fit to grain size indicate the fine content (>4Φ )in grain size distribution was derived from northwest China, the fine content (<4Φ ) in Bohai Sea seabed was deposited when sea level was low during last glacial period. |
