摘要
本文认为,闽东南沿海的气候为南亚热带半湿润气候;土壤属半干润老成土;原生植被不可能是湿润季雨林,而可能是具有旱生特征的常绿硬叶阔叶和针叶混交林或森林灌丛;在土地利用上以旱作为特征,应把该区与台湾海峡一起作为一个自然区划单元划出,建议称为闽东南沿海与台湾海峡半岛岛屿州。
According to the distribution, seasonal and perennial change of aridity, the south-eastern coastal region of Fujian and Taiwan strait are considered as a semi-moist region. The representative soils in the region are Ustults, whose moisture control horizen has a more than 90 days and less than 185 days of dry period each year. In comparison with that of soils in the Southern subtropical humid region, the content of free iron oxide of the soils in the region, which were derived from the same parent material, is apparently smaller. On the basis of the spore-pollen analysis for some deposits and the fact that both precipitation and aridity of this region are obviously different from those of typical places in the southern subtropical zone where monsoon rainforest has remained, we hold that the primary vegetation in the region maybe sclerophyllous-coniferous mixed forest with the apparent aerophytic characters or scrub with forest rather than the southern tropical monsoon rainforest. In addition, the agricultural production and land utilization as well as territorial development of the region are evidently lifferent from those of the humid region next to the west of the region. Therefore, it is essential to classify the south-eastern coastal region of Fujian as a regional unit from the specific grade of physical geographic regionalization.
