| 摘 要： | 文章利用海南岛SOTER数据库及自动土地评价模型ALES评价结果,对海南岛4种主要母岩上发育的土壤类型、土壤性质及香蕉种植适宜性与母质的关系进行了分析。海南岛不同母岩上土壤类型的发育呈现多样性,土壤类型的分布明显受到母岩类型、成土年龄、成土环境等因素的影响。酸性火成岩上主要发育有雏形土和富铁土,基性岩上则主要是发育良好的铁铝土,碎屑岩上主要是雏形土,而海相沉积物由于土壤形成时间的差异出现了多样的土壤类型。在海南岛湿热的气候条件下,原生母岩上发育的土壤,尽管成土母岩成分各不相同,但一些土壤性质已经没有明显差别,如交换性钙、镁、钠等,部分土壤化学性质如交换性钾的含量继承了母岩特性。各种母岩上发育的土壤,在自然条件下,适宜香蕉种植的比例都很低,但基性火成岩和海积物上发育的土壤,更容易受到人为管理措施的影响,如果满足一定的技术和经济投入,海南岛热带作物的种植潜力可以得到进一步的挖掘。

| Abstract: | Soil types, soil attributes, and land suitability for cultivating banana of four types of parent rocks were analyzed in this paper based on the HaiSOTER (Soil and Terrain Digital Database) database and ALES model (Automated Land Evaluation System). Cambosols and Ferrosols were the dominating soil typess on the parent material of acid igneous, Cambosols on clastic sediments, Ferralosols on basic igneous, Primosols and Cambosols on marine sediments. Soil types developed from different parent rocks were clearly influenced by parent rocks, soil age, soil genesis environment et al. Soil sequences were closely related to the type of parent rocks. But the strong wreathing condition of tropical climate changed the simple successive relationship from parent rocks to soils in Hainan. Soil age, topography, and local environment show their influence on soil distribution developed from the same parent rock. Soils developed from clastic sediments keep more features which inherited from parent rocks than soils developed from others parent rocks. Under the tropical climate condition which means strong weathering process and heavy biological activities in Hainan, some soil attributes show invisible difference among parent rocks such as the contents of exchangeable Ca 2 , Mg 2 and Na , at the same time; some show clear successive features from mother materials such as exchangeable K content in soils developed from acid igneous because of the high content of potash feldspar in parent rocks. The suitability for planting banana is very low for soils developed from four parent rocks without factitious technological and financial input. But for soils developed from basic igneous and marine materials, the suitability can be notably enhanced with the condition of moderate technological and financial input. This is because soils developed from basic igneous and marine materials were limited rather by water and fertilizer supplies than by landform or climate. Water and fertilizer supplies are readily-changed with technological and financial input. So, the potential for planting banana in Hainan is considerable if the desire for technological and financial input can be met. |
