The characteristics,genesis,distribution patterns and classification of soils,which change with micro-topography and vegetation under the warm temperate climate in the Fukiage coastal dune of South Kyushu,Japan,were investigated here.A series of soils, which change with micro-topography and vegetation in the Fukiage coastal dune,is regularly developed. And a new type soil which has a bleached horizon and an accumulation layer with iron mottlings and which is not reported in Japan until now is developed under pine (Pinus thunbergn) - moss (Hypnum plumaeforme) forest in the terrace-like sand hills.Topo- and bio-sequence of the soils in the Fukiage coastal dune is as fallow.Protic Alenosols (Calcaric) are developed under non-vegetation on the front slope of the front sand hill,Haplic Alenosols (Calcaric) under maritime scrub on the top of the front sand hill,Haplic Alenosols (Hypereutric) under pine-Japanese pampas grass forest on the back slope of the front sand hill,Endogleyic Alenosols (Hypereutric) under moist-soil plants grassland in the marsh,Brunic Albic Alenosols (Endoeutric) and Brunic Albic Alenosols (Hyperdystric) under pine - moss forest on the three steps of the terrace-like sand hills,and Haplic Alenosols (Endoeutric) under evergreen broad-leaved tree forest in the back sand hill.The series of soils, which change with micro-topography and vegetation in the Fukiage coastal dune,is classified very appropriately according to the world reference base for soil resources (WRB). These soils,however,cannot be well classified according to any soil classification system of Japan. The improvement of soil groups and subgroups is required for it.

对日本南九州福上海岸沙丘暖温带气候条件下随微地形和植被变化的土壤特征、成因、分布格局和分类进行了研究。并在松树下形成了一种新的土壤类型，这种土壤具有漂白层和铁斑驳的堆积层，迄今为止在日本还没有报道（Pinus thunbergn）-苔藓（Hypnum plumaeforme）森林在阶地状沙山中。福建上海岸沙丘的土壤的地形和生物序列是休闲的。（石灰质）发育于前沙山前坡无植被下的浅成粉土在前沙山顶部的海洋灌木丛下，单一旱成土（超电）前沙山后坡松-日本潘帕斯草原草地下，潜育性白腐土（过中性）沼泽地植物草地下的土壤，褐白质粉土（内育）和褐白质粉土（Hyperdystric）下松苔林的三阶状沙山，根据世界土壤资源参考库（WRB）的分类方法，对福建省海岸沙丘的土壤进行了分类，并将其划分为随微地形和植被变化而变化的土壤系列。然而，这些土壤不能很好地根据日本的任何土壤分类系统进行分类。这就要求对土壤类群和亚类进行改良。
